* fix: add base_dir path containment to FileWriterTool

os.path.join does not prevent traversal — joining "./" with "../../../etc/cron.d/pwned"
resolves cleanly outside any intended scope. The tool also called os.makedirs on
the unvalidated path, meaning it would create arbitrary directory structures.

Adds a base_dir parameter that uses os.path.realpath() to resolve the final path
(including symlinks) before checking containment. Any filename or directory argument
that resolves outside base_dir is rejected before any filesystem operation occurs.

When base_dir is not set the tool behaves as before — only use that in fully
sandboxed environments.

* fix: make directory relative to base_dir for better UX

When base_dir is set, the directory arg is now treated as a subdirectory
of base_dir rather than an absolute path. This means the LLM only needs
to specify a filename (and optionally a relative subdirectory) — it does
not need to repeat the base_dir path.

  FileWriterTool(base_dir="./output")
  → filename="report.txt"            writes to ./output/report.txt
  → filename="f.txt", directory="sub" writes to ./output/sub/f.txt

* fix: remove directory field from LLM schema when base_dir is set

When a developer sets base_dir, they control where files are written.
The LLM should only supply filename and content — not a directory path.

Adds ScopedFileWriterToolInput (no directory field) which is used when
base_dir is provided at construction, following the same pattern as
FileReadTool/ScrapeWebsiteTool.

* fix: prevent path traversal in FileWriterTool without interface changes

Adds containment check inside _run() using os.path.realpath() to ensure
the resolved file path stays within the resolved directory. Blocks ../
sequences, absolute filenames, and symlink escapes transparently —
no schema or interface changes required.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix: use Path.is_relative_to() for path containment check

Replaces startswith(real_directory + os.sep) with Path.is_relative_to(),
which does a proper path-component comparison. This avoids the edge case
where real_directory == "/" produces a "//" prefix, and is safe on
case-insensitive filesystems. Also explicitly rejects the case where
the filepath resolves to the directory itself (not a valid file target).

* test: fix portability issues in path traversal tests

- test_blocks_traversal_in_filename: use a sibling temp dir instead of
  asserting against a potentially pre-existing ../outside.txt
- test_blocks_absolute_path_in_filename: use a temp-dir-derived absolute
  path instead of hardcoding /etc/passwd
- test_blocks_symlink_escape: symlink to a temp "outside" dir instead of
  /etc, assert target file was not created

-CrewAI AMP provides a powerful way to capture telemetry logs from your deployments. This allows you to monitor the performance of your agents and workflows, and to debug issues that may arise.
+CrewAI AMP can export OpenTelemetry **traces** and **logs** from your deployments directly to your own collector. This lets you monitor agent performance, track LLM calls, and debug issues using your existing observability stack.
+
+Telemetry data follows the [OpenTelemetry GenAI semantic conventions](https://opentelemetry.io/docs/specs/semconv/gen-ai/) plus additional CrewAI-specific attributes.

+
+CrewAI AMP supports connecting to any MCP server that implements the [Model Context Protocol](https://modelcontextprotocol.io/). You can bring public servers that require no authentication, servers protected by an API key or bearer token, and servers that use OAuth 2.0 for secure delegated access.
+
+## Prerequisites

+
+## Adding a Custom MCP Server
+
+<Steps>
+    <Step title="Open Tools & Integrations">
+        Navigate to **Tools & Integrations** in the left sidebar of CrewAI AMP, then select the **Connections** tab.
+    </Step>
+
+    <Step title="Start adding a Custom MCP Server">
+        Click the **Add Custom MCP Server** button. A dialog will appear with the configuration form.
+    </Step>
+
+    <Step title="Fill in the basic information">
+        - **Name** (required): A descriptive name for your MCP server (e.g., "My Internal Tools Server").
+        - **Description**: An optional summary of what this MCP server provides.
+        - **Server URL** (required): The full URL to your MCP server endpoint (e.g., `https://my-server.example.com/mcp`).
+    </Step>
+
+    <Step title="Choose an authentication method">
+        Select one of the three available authentication methods based on how your MCP server is secured. See the sections below for details on each method.
+    </Step>
+
+    <Step title="Add custom headers (optional)">
+        If your MCP server requires additional headers on every request (e.g., tenant identifiers or routing headers), click **+ Add Header** and provide the header name and value. You can add multiple custom headers.
+    </Step>
+
+    <Step title="Create the connection">
+        Click **Create MCP Server** to save the connection. Your custom MCP server will now appear in the Connections list and its tools will be available for use in your crews.
+    </Step>
+</Steps>
+
+## Authentication Methods
+
+### No Authentication
+
+Choose this option when your MCP server is publicly accessible and does not require any credentials. This is common for open-source or internal servers running behind a VPN.
+
+### Authentication Token
+
+Use this method when your MCP server is protected by an API key or bearer token.
+
+<Frame>
+    <img src="/images/enterprise/custom-mcp-auth-token.png" alt="Custom MCP Server with Authentication Token" />
+</Frame>
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| **Header Name** | Yes | The name of the HTTP header that carries the token (e.g., `X-API-Key`, `Authorization`). |
+| **Value** | Yes | Your API key or bearer token. |
+| **Add to** | No | Where to attach the credential — **Header** (default) or **Query parameter**. |
+
+<Tip>
+If your server expects a `Bearer` token in the `Authorization` header, set the Header Name to `Authorization` and the Value to `Bearer <your-token>`.
+</Tip>
+
+### OAuth 2.0
+
+Use this method for MCP servers that require OAuth 2.0 authorization. CrewAI will handle the full OAuth flow, including token refresh.
+
+<Frame>
+    <img src="/images/enterprise/custom-mcp-oauth.png" alt="Custom MCP Server with OAuth 2.0" />
+</Frame>
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| **Redirect URI** | — | Pre-filled and read-only. Copy this URI and register it as an authorized redirect URI in your OAuth provider. |
+| **Authorization Endpoint** | Yes | The URL where users are sent to authorize access (e.g., `https://auth.example.com/oauth/authorize`). |
+| **Token Endpoint** | Yes | The URL used to exchange the authorization code for an access token (e.g., `https://auth.example.com/oauth/token`). |
+| **Client ID** | Yes | The OAuth client ID issued by your provider. |
+| **Client Secret** | No | The OAuth client secret. Not required for public clients using PKCE. |
+| **Scopes** | No | Space-separated list of scopes to request (e.g., `read write`). |
+| **Token Auth Method** | No | How the client credentials are sent when exchanging tokens — **Standard (POST body)** or **Basic Auth (header)**. Defaults to Standard. |
+| **PKCE Supported** | No | Enable if your OAuth provider supports Proof Key for Code Exchange. Recommended for improved security. |
+
+<Info>
+**Discover OAuth Config**: If your OAuth provider supports OpenID Connect Discovery, click the **Discover OAuth Config** link to auto-populate the authorization and token endpoints from the provider's `/.well-known/openid-configuration` URL.
+</Info>
+
+#### Setting Up OAuth 2.0 Step by Step
+
+<Steps>
+    <Step title="Register the redirect URI">
+        Copy the **Redirect URI** shown in the form and add it as an authorized redirect URI in your OAuth provider's application settings.
+    </Step>
+
+    <Step title="Enter endpoints and credentials">
+        Fill in the **Authorization Endpoint**, **Token Endpoint**, **Client ID**, and optionally the **Client Secret** and **Scopes**.
+    </Step>
+
+    <Step title="Configure token exchange method">
+        Select the appropriate **Token Auth Method**. Most providers use the default **Standard (POST body)**. Some older providers require **Basic Auth (header)**.
+    </Step>
+
+    <Step title="Enable PKCE (recommended)">
+        Check **PKCE Supported** if your provider supports it. PKCE adds an extra layer of security to the authorization code flow and is recommended for all new integrations.
+    </Step>
+
+    <Step title="Create and authorize">
+        Click **Create MCP Server**. You will be redirected to your OAuth provider to authorize access. Once authorized, CrewAI will store the tokens and automatically refresh them as needed.
+    </Step>
+</Steps>
+
+## Using Your Custom MCP Server
+
+Once connected, your custom MCP server's tools appear alongside built-in connections on the **Tools & Integrations** page. You can:
+
+- **Assign tools to agents** in your crews just like any other CrewAI tool.
+- **Manage visibility** to control which team members can use the server.
+- **Edit or remove** the connection at any time from the Connections list.
+
+<Warning>
+If your MCP server becomes unreachable or the credentials expire, tool calls using that server will fail. Make sure the server URL is stable and credentials are kept up to date.
+</Warning>

+title: Publish Custom Tools
+description: How to build, package, and publish your own CrewAI-compatible tools to PyPI so any CrewAI user can install and use them.
+icon: box-open
+mode: "wide"
+---
+
+## Overview
+
+CrewAI's tool system is designed to be extended. If you've built a tool that could benefit others, you can package it as a standalone Python library, publish it to PyPI, and make it available to any CrewAI user — no PR to the CrewAI repo required.
+
+This guide walks through the full process: implementing the tools contract, structuring your package, and publishing to PyPI.
+
+<Note type="info" title="Not looking to publish?">
+If you just need a custom tool for your own project, see the [Create Custom Tools](/en/learn/create-custom-tools) guide instead.
+</Note>
+
+## The Tools Contract
+
+Every CrewAI tool must satisfy one of two interfaces:
+
+### Option 1: Subclass `BaseTool`
+
+Subclass `crewai.tools.BaseTool` and implement the `_run` method. Define `name`, `description`, and optionally an `args_schema` for input validation.
+
+```python
+from crewai.tools import BaseTool
+from pydantic import BaseModel, Field
+
+
+class GeolocateInput(BaseModel):
+    """Input schema for GeolocateTool."""
+    address: str = Field(..., description="The street address to geolocate.")
+
+
+class GeolocateTool(BaseTool):
+    name: str = "Geolocate"
+    description: str = "Converts a street address into latitude/longitude coordinates."
+    args_schema: type[BaseModel] = GeolocateInput
+
+    def _run(self, address: str) -> str:
+        # Your implementation here
+        return f"40.7128, -74.0060"
+```
+
+### Option 2: Use the `@tool` Decorator
+
+For simpler tools, the `@tool` decorator turns a function into a CrewAI tool. The function **must** have a docstring (used as the tool description) and type annotations.
+
+```python
+from crewai.tools import tool
+
+
+@tool("Geolocate")
+def geolocate(address: str) -> str:
+    """Converts a street address into latitude/longitude coordinates."""
+    return "40.7128, -74.0060"
+```
+
+### Key Requirements
+
+Regardless of which approach you use, your tool must:
+
+- Have a **`name`** — a short, descriptive identifier.
+- Have a **`description`** — tells the agent when and how to use the tool. This directly affects how well agents use your tool, so be clear and specific.
+- Implement **`_run`** (BaseTool) or provide a **function body** (@tool) — the synchronous execution logic.
+- Use **type annotations** on all parameters and return values.
+- Return a **string** result (or something that can be meaningfully converted to one).
+
+### Optional: Async Support
+
+If your tool performs I/O-bound work, implement `_arun` for async execution:
+
+```python
+class GeolocateTool(BaseTool):
+    name: str = "Geolocate"
+    description: str = "Converts a street address into latitude/longitude coordinates."
+
+    def _run(self, address: str) -> str:
+        # Sync implementation
+        ...
+
+    async def _arun(self, address: str) -> str:
+        # Async implementation
+        ...
+```
+
+### Optional: Input Validation with `args_schema`
+
+Define a Pydantic model as your `args_schema` to get automatic input validation and clear error messages. If you don't provide one, CrewAI will infer it from your `_run` method's signature.
+
+```python
+from pydantic import BaseModel, Field
+
+
+class TranslateInput(BaseModel):
+    """Input schema for TranslateTool."""
+    text: str = Field(..., description="The text to translate.")
+    target_language: str = Field(
+        default="en",
+        description="ISO 639-1 language code for the target language.",
+    )
+```
+
+Explicit schemas are recommended for published tools — they produce better agent behavior and clearer documentation for your users.
+
+### Optional: Environment Variables
+
+If your tool requires API keys or other configuration, declare them with `env_vars` so users know what to set:
+
+```python
+from crewai.tools import BaseTool, EnvVar
+
+
+class GeolocateTool(BaseTool):
+    name: str = "Geolocate"
+    description: str = "Converts a street address into latitude/longitude coordinates."
+    env_vars: list[EnvVar] = [
+        EnvVar(
+            name="GEOCODING_API_KEY",
+            description="API key for the geocoding service.",
+            required=True,
+        ),
+    ]
+
+    def _run(self, address: str) -> str:
+        ...
+```
+
+## Package Structure
+
+Structure your project as a standard Python package. Here's a recommended layout:
+
+```
+crewai-geolocate/
+├── pyproject.toml
+├── LICENSE
+├── README.md
+└── src/
+    └── crewai_geolocate/
+        ├── __init__.py
+        └── tools.py
+```
+
+### `pyproject.toml`
+
+```toml
+[project]
+name = "crewai-geolocate"
+version = "0.1.0"
+description = "A CrewAI tool for geolocating street addresses."
+requires-python = ">=3.10"
+dependencies = [
+    "crewai",
+]
+
+[build-system]
+requires = ["hatchling"]
+build-backend = "hatchling.build"
+```
+
+Declare `crewai` as a dependency so users get a compatible version automatically.
+
+### `__init__.py`
+
+Re-export your tool classes so users can import them directly:
+
+```python
+from crewai_geolocate.tools import GeolocateTool
+
+__all__ = ["GeolocateTool"]
+```
+
+### Naming Conventions
+
+- **Package name**: Use the prefix `crewai-` (e.g., `crewai-geolocate`). This makes your tool discoverable when users search PyPI.
+- **Module name**: Use underscores (e.g., `crewai_geolocate`).
+- **Tool class name**: Use PascalCase ending in `Tool` (e.g., `GeolocateTool`).
+
+## Testing Your Tool
+
+Before publishing, verify your tool works within a crew:
+
+```python
+from crewai import Agent, Crew, Task
+from crewai_geolocate import GeolocateTool
+
+agent = Agent(
+    role="Location Analyst",
+    goal="Find coordinates for given addresses.",
+    backstory="An expert in geospatial data.",
+    tools=[GeolocateTool()],
+)
+
+task = Task(
+    description="Find the coordinates of 1600 Pennsylvania Avenue, Washington, DC.",
+    expected_output="The latitude and longitude of the address.",
+    agent=agent,
+)
+
+crew = Crew(agents=[agent], tasks=[task])
+result = crew.kickoff()
+print(result)
+```
+
+## Publishing to PyPI
+
+Once your tool is tested and ready:
+
+```bash
+# Build the package
+uv build
+
+# Publish to PyPI
+uv publish
+```
+
+If this is your first time publishing, you'll need a [PyPI account](https://pypi.org/account/register/) and an [API token](https://pypi.org/help/#apitoken).
+
+### After Publishing
+
+Users can install your tool with:
+
+```bash
+pip install crewai-geolocate
+```
+
+Or with uv:
+
+```bash
+uv add crewai-geolocate
+```
+
+Then use it in their crews:
+
+```python
+from crewai_geolocate import GeolocateTool
+
+agent = Agent(
+    role="Location Analyst",
+    tools=[GeolocateTool()],
+    # ...
+)
+```

-# `EXASearchTool`
-
-## Description
-
-The EXASearchTool is designed to perform a semantic search for a specified query from a text's content across the internet. 
-It utilizes the [exa.ai](https://exa.ai/) API to fetch and display the most relevant search results based on the query provided by the user.
+The `EXASearchTool` lets CrewAI agents search the web using the [Exa](https://exa.ai/) search API. It returns the most relevant results for any query, with options for full page content and AI-generated summaries.
 
 ## Installation
 
-To incorporate this tool into your project, follow the installation instructions below:
+Install the CrewAI tools package:
 
 ```shell
 pip install 'crewai[tools]'
 ```
 
-## Example
+## Environment Variables
 
-The following example demonstrates how to initialize the tool and execute a search with a given query:
+Set your Exa API key as an environment variable:
 
-```python Code
-from crewai_tools import EXASearchTool
-
-# Initialize the tool for internet searching capabilities
-tool = EXASearchTool()
+```bash
+export EXA_API_KEY='your_exa_api_key'
 ```
 
-## Steps to Get Started
+Get an API key from the [Exa dashboard](https://dashboard.exa.ai/api-keys).
 
-To effectively use the EXASearchTool, follow these steps:
+## Example Usage
 
-<Steps>
-    <Step title="Package Installation">
-        Confirm that the `crewai[tools]` package is installed in your Python environment.
-    </Step>
-    <Step title="API Key Acquisition">
-        Acquire a [exa.ai](https://exa.ai/) API key by registering for a free account at [exa.ai](https://exa.ai/).
-    </Step>
-    <Step title="Environment Configuration">
-        Store your obtained API key in an environment variable named `EXA_API_KEY` to facilitate its use by the tool.
-    </Step>
-</Steps>
+Here's how to use the `EXASearchTool` within a CrewAI agent:
 
-## Conclusion
+```python
+import os
+from crewai import Agent, Task, Crew
+from crewai_tools import EXASearchTool
 
-By integrating the `EXASearchTool` into Python projects, users gain the ability to conduct real-time, relevant searches across the internet directly from their applications. 
-By adhering to the setup and usage guidelines provided, incorporating this tool into projects is streamlined and straightforward.
+# Initialize the tool
+exa_tool = EXASearchTool()
+
+# Create an agent that uses the tool
+researcher = Agent(
+    role='Research Analyst',
+    goal='Find the latest information on any topic',
+    backstory='An expert researcher who finds the most relevant and up-to-date information.',
+    tools=[exa_tool],
+    verbose=True
+)
+
+# Create a task for the agent
+research_task = Task(
+    description='Find the top 3 recent breakthroughs in quantum computing.',
+    expected_output='A summary of the top 3 breakthroughs with source URLs.',
+    agent=researcher
+)
+
+# Form the crew and kick it off
+crew = Crew(
+    agents=[researcher],
+    tasks=[research_task],
+    verbose=True
+)
+
+result = crew.kickoff()
+print(result)
+```
+
+## Configuration Options
+
+The `EXASearchTool` accepts the following parameters during initialization:
+
+- `type` (str, optional): The search type to use. Defaults to `"auto"`. Options: `"auto"`, `"instant"`, `"fast"`, `"deep"`.
+- `content` (bool, optional): Whether to include full page content in results. Defaults to `False`.
+- `summary` (bool, optional): Whether to include AI-generated summaries of each result. Requires `content=True`. Defaults to `False`.
+- `api_key` (str, optional): Your Exa API key. Falls back to the `EXA_API_KEY` environment variable if not provided.
+- `base_url` (str, optional): Custom API server URL. Falls back to the `EXA_BASE_URL` environment variable if not provided.
+
+When calling the tool (or when an agent invokes it), the following search parameters are available:
+
+- `search_query` (str): **Required**. The search query string.
+- `start_published_date` (str, optional): Filter results published after this date (ISO 8601 format, e.g. `"2024-01-01"`).
+- `end_published_date` (str, optional): Filter results published before this date (ISO 8601 format).
+- `include_domains` (list[str], optional): A list of domains to restrict the search to.
+
+## Advanced Usage
+
+You can configure the tool with custom parameters for richer results:
+
+```python
+# Get full page content with AI summaries
+exa_tool = EXASearchTool(
+    content=True,
+    summary=True,
+    type="deep"
+)
+
+# Use it in an agent
+agent = Agent(
+    role="Deep Researcher",
+    goal="Conduct thorough research with full content and summaries",
+    tools=[exa_tool]
+)
+```
+
+## Features
+
+- **Semantic Search**: Find results based on meaning, not just keywords
+- **Full Content Retrieval**: Get the full text of web pages alongside search results
+- **AI Summaries**: Get concise, AI-generated summaries of each result
+- **Date Filtering**: Limit results to specific time periods with published date filters
+- **Domain Filtering**: Restrict searches to specific domains

+description: AGENTS.md를 사용하여 CrewAI 프로젝트 전반에서 코딩 에이전트와 IDE를 안내합니다.
+icon: terminal
+mode: "wide"
+---
+
+## AGENTS.md를 사용하는 이유
+
+`AGENTS.md`는 가벼운 저장소 로컬 지침 파일로, 코딩 에이전트에게 일관되고 프로젝트별 안내를 제공합니다. 프로젝트 루트에 배치하고 어시스턴트가 작업하는 방식(컨벤션, 명령어, 아키텍처 노트, 가드레일)에 대한 신뢰할 수 있는 소스로 활용하세요.
+
+## CLI로 프로젝트 생성
+
+CrewAI CLI를 사용하여 프로젝트를 스캐폴딩하면, `AGENTS.md`가 루트에 자동으로 추가됩니다.
+
+```bash
+# Crew
+crewai create crew my_crew
+
+# Flow
+crewai create flow my_flow
+
+# Tool repository
+crewai tool create my_tool
+```
+
+## 도구 설정: 어시스턴트에 AGENTS.md 연결
+
+### Codex
+
+Codex는 저장소에 배치된 `AGENTS.md` 파일로 안내할 수 있습니다. 컨벤션, 명령어, 워크플로우 기대치 등 지속적인 프로젝트 컨텍스트를 제공하는 데 사용하세요.
+
+### Claude Code
+
+Claude Code는 프로젝트 메모리를 `CLAUDE.md`에 저장합니다. `/init`으로 부트스트랩하고 `/memory`로 편집할 수 있습니다. Claude Code는 `CLAUDE.md` 내에서 임포트도 지원하므로, `@AGENTS.md`와 같은 한 줄을 추가하여 공유 지침을 중복 없이 가져올 수 있습니다.
+
+간단하게 다음과 같이 사용할 수 있습니다:
+
+```bash
+mv AGENTS.md CLAUDE.md
+```
+
+### Gemini CLI와 Google Antigravity
+
+Gemini CLI와 Antigravity는 저장소 루트 및 상위 디렉토리에서 프로젝트 컨텍스트 파일(기본값: `GEMINI.md`)을 로드합니다. Gemini CLI 설정에서 `context.fileName`을 설정하여 `AGENTS.md`를 대신(또는 추가로) 읽도록 구성할 수 있습니다. 예를 들어, `AGENTS.md`만 설정하거나 각 도구의 형식을 유지하고 싶다면 `AGENTS.md`와 `GEMINI.md`를 모두 포함할 수 있습니다.
+
+간단하게 다음과 같이 사용할 수 있습니다:
+
+```bash
+mv AGENTS.md GEMINI.md
+```
+
+### Cursor
+
+Cursor는 `AGENTS.md`를 프로젝트 지침 파일로 지원합니다. 프로젝트 루트에 배치하여 Cursor의 코딩 어시스턴트에 안내를 제공하세요.
+
+### Windsurf
+
+Claude Code는 Windsurf와의 공식 통합을 제공합니다. Windsurf 내에서 Claude Code를 사용하는 경우, 위의 Claude Code 안내를 따르고 `CLAUDE.md`에서 `AGENTS.md`를 임포트하세요.
+
+Windsurf의 네이티브 어시스턴트를 사용하는 경우, 프로젝트 규칙 또는 지침 기능(사용 가능한 경우)을 구성하여 `AGENTS.md`에서 읽거나 내용을 직접 붙여넣으세요.

+
+## 개요
+
+CrewAI의 도구 시스템은 확장 가능하도록 설계되었습니다. 다른 사용자에게도 유용한 도구를 만들었다면, 독립적인 Python 라이브러리로 패키징하여 PyPI에 게시하고 모든 CrewAI 사용자가 사용할 수 있도록 할 수 있습니다. CrewAI 저장소에 PR을 보낼 필요가 없습니다.
+
+이 가이드에서는 도구 계약 구현, 패키지 구조화, PyPI 게시까지의 전체 과정을 안내합니다.
+
+<Note type="info" title="배포할 계획이 없으신가요?">
+프로젝트 내에서만 사용할 커스텀 도구가 필요하다면 [커스텀 도구 생성](/ko/learn/create-custom-tools) 가이드를 참고하세요.
+</Note>
+
+## 도구 계약
+
+모든 CrewAI 도구는 다음 두 가지 인터페이스 중 하나를 충족해야 합니다:
+
+### 옵션 1: `BaseTool` 서브클래싱
+
+`crewai.tools.BaseTool`을 서브클래싱하고 `_run` 메서드를 구현합니다. `name`, `description`, 그리고 선택적으로 입력 검증을 위한 `args_schema`를 정의합니다.
+
+```python
+from crewai.tools import BaseTool
+from pydantic import BaseModel, Field
+
+
+class GeolocateInput(BaseModel):
+    """GeolocateTool의 입력 스키마."""
+    address: str = Field(..., description="지오코딩할 도로명 주소.")
+
+
+class GeolocateTool(BaseTool):
+    name: str = "Geolocate"
+    description: str = "도로명 주소를 위도/경도 좌표로 변환합니다."
+    args_schema: type[BaseModel] = GeolocateInput
+
+    def _run(self, address: str) -> str:
+        # 구현 로직
+        return f"40.7128, -74.0060"
+```
+
+### 옵션 2: `@tool` 데코레이터 사용
+
+간단한 도구의 경우, `@tool` 데코레이터로 함수를 CrewAI 도구로 변환할 수 있습니다. 함수에는 반드시 독스트링(도구 설명으로 사용됨)과 타입 어노테이션이 있어야 합니다.
+
+```python
+from crewai.tools import tool
+
+
+@tool("Geolocate")
+def geolocate(address: str) -> str:
+    """도로명 주소를 위도/경도 좌표로 변환합니다."""
+    return "40.7128, -74.0060"
+```
+
+### 핵심 요구사항
+
+어떤 방식을 사용하든, 도구는 다음을 충족해야 합니다:
+
+- **`name`** — 짧고 설명적인 식별자.
+- **`description`** — 에이전트에게 도구를 언제, 어떻게 사용할지 알려줍니다. 에이전트가 도구를 얼마나 잘 활용하는지에 직접적으로 영향을 미치므로 명확하고 구체적으로 작성하세요.
+- **`_run`** (BaseTool) 또는 **함수 본문** (@tool) 구현 — 동기 실행 로직.
+- 모든 매개변수와 반환 값에 **타입 어노테이션** 사용.
+- **문자열** 결과를 반환 (또는 의미 있게 문자열로 변환 가능한 값).
+
+### 선택사항: 비동기 지원
+
+I/O 바운드 작업을 수행하는 도구의 경우 비동기 실행을 위해 `_arun`을 구현합니다:
+
+```python
+class GeolocateTool(BaseTool):
+    name: str = "Geolocate"
+    description: str = "도로명 주소를 위도/경도 좌표로 변환합니다."
+
+    def _run(self, address: str) -> str:
+        # 동기 구현
+        ...
+
+    async def _arun(self, address: str) -> str:
+        # 비동기 구현
+        ...
+```
+
+### 선택사항: `args_schema`를 통한 입력 검증
+
+Pydantic 모델을 `args_schema`로 정의하면 자동 입력 검증과 명확한 에러 메시지를 받을 수 있습니다. 제공하지 않으면 CrewAI가 `_run` 메서드의 시그니처에서 추론합니다.
+
+```python
+from pydantic import BaseModel, Field
+
+
+class TranslateInput(BaseModel):
+    """TranslateTool의 입력 스키마."""
+    text: str = Field(..., description="번역할 텍스트.")
+    target_language: str = Field(
+        default="en",
+        description="대상 언어의 ISO 639-1 언어 코드.",
+    )
+```
+
+배포용 도구에는 명시적 스키마를 권장합니다 — 에이전트 동작이 개선되고 사용자에게 더 명확한 문서를 제공합니다.
+
+### 선택사항: 환경 변수
+
+도구에 API 키나 기타 설정이 필요한 경우, `env_vars`로 선언하여 사용자가 무엇을 설정해야 하는지 알 수 있도록 합니다:
+
+```python
+from crewai.tools import BaseTool, EnvVar
+
+
+class GeolocateTool(BaseTool):
+    name: str = "Geolocate"
+    description: str = "도로명 주소를 위도/경도 좌표로 변환합니다."
+    env_vars: list[EnvVar] = [
+        EnvVar(
+            name="GEOCODING_API_KEY",
+            description="지오코딩 서비스 API 키.",
+            required=True,
+        ),
+    ]
+
+    def _run(self, address: str) -> str:
+        ...

+---
+
+O CrewAI AMP pode exportar **traces** e **logs** do OpenTelemetry das suas implantações diretamente para seu próprio coletor. Isso permite que você monitore o desempenho dos agentes, rastreie chamadas de LLM e depure problemas usando sua stack de observabilidade existente.
+
+Os dados de telemetria seguem as [convenções semânticas GenAI do OpenTelemetry](https://opentelemetry.io/docs/specs/semconv/gen-ai/) além de atributos adicionais específicos do CrewAI.
+
+## Pré-requisitos
+
+<CardGroup cols={2}>
+  <Card title="Conta CrewAI AMP" icon="users">
+    Sua organização deve ter uma conta CrewAI AMP ativa.
+  </Card>
+  <Card title="Coletor OpenTelemetry" icon="server">
+    Você precisa de um endpoint de coletor compatível com OpenTelemetry (por exemplo, seu próprio OTel Collector, Datadog, Grafana ou qualquer backend compatível com OTLP).
+  </Card>
+</CardGroup>
+
+## Configurando um coletor
+
+1. No CrewAI AMP, vá para **Settings** > **OpenTelemetry Collectors**.
+2. Clique em **Add Collector**.
+3. Selecione um tipo de integração — **OpenTelemetry Traces** ou **OpenTelemetry Logs**.
+4. Configure a conexão:
+   - **Endpoint** — O endpoint OTLP do seu coletor (por exemplo, `https://otel-collector.example.com:4317`).
+   - **Service Name** — Um nome para identificar este serviço na sua plataforma de observabilidade.
+   - **Custom Headers** *(opcional)* — Adicione headers de autenticação ou roteamento como pares chave-valor.
+   - **Certificate** *(opcional)* — Forneça um certificado TLS se o seu coletor exigir um.
+5. Clique em **Save**.

+description: "Conecte seus próprios servidores MCP ao CrewAI AMP com acesso público, autenticação por token ou OAuth 2.0"
+icon: "plug"
+mode: "wide"
+---
+
+O CrewAI AMP suporta a conexão com qualquer servidor MCP que implemente o [Model Context Protocol](https://modelcontextprotocol.io/). Você pode conectar servidores públicos que não exigem autenticação, servidores protegidos por chave de API ou token bearer, e servidores que utilizam OAuth 2.0 para acesso delegado seguro.
+
+## Pré-requisitos
+
+<CardGroup cols={2}>
+  <Card title="Conta CrewAI AMP" icon="user">
+    Você precisa de uma conta ativa no [CrewAI AMP](https://app.crewai.com).
+  </Card>
+  <Card title="URL do Servidor MCP" icon="link">
+    A URL do servidor MCP que você deseja conectar. O servidor deve ser acessível pela internet e suportar transporte Streamable HTTP.
+  </Card>
+</CardGroup>
+
+## Adicionando um Servidor MCP Personalizado
+
+<Steps>
+    <Step title="Acesse Tools & Integrations">
+        Navegue até **Tools & Integrations** no menu lateral esquerdo do CrewAI AMP e selecione a aba **Connections**.
+    </Step>
+
+    <Step title="Inicie a adição de um Servidor MCP Personalizado">
+        Clique no botão **Add Custom MCP Server**. Um diálogo aparecerá com o formulário de configuração.
+    </Step>
+
+    <Step title="Preencha as informações básicas">
+        - **Name** (obrigatório): Um nome descritivo para seu servidor MCP (ex.: "Meu Servidor de Ferramentas Internas").
+        - **Description**: Um resumo opcional do que este servidor MCP fornece.
+        - **Server URL** (obrigatório): A URL completa do endpoint do seu servidor MCP (ex.: `https://my-server.example.com/mcp`).
+    </Step>
+
+    <Step title="Escolha um método de autenticação">
+        Selecione um dos três métodos de autenticação disponíveis com base em como seu servidor MCP está protegido. Veja as seções abaixo para detalhes sobre cada método.
+    </Step>
+
+    <Step title="Adicione headers personalizados (opcional)">
+        Se seu servidor MCP requer headers adicionais em cada requisição (ex.: identificadores de tenant ou headers de roteamento), clique em **+ Add Header** e forneça o nome e valor do header. Você pode adicionar múltiplos headers personalizados.
+    </Step>
+
+    <Step title="Crie a conexão">
+        Clique em **Create MCP Server** para salvar a conexão. Seu servidor MCP personalizado aparecerá na lista de Connections e suas ferramentas estarão disponíveis para uso nas suas crews.
+    </Step>
+</Steps>
+
+## Métodos de Autenticação
+
+### Sem Autenticação
+
+Escolha esta opção quando seu servidor MCP é publicamente acessível e não requer nenhuma credencial. Isso é comum para servidores open-source ou servidores internos rodando atrás de uma VPN.
+
+### Token de Autenticação
+
+Use este método quando seu servidor MCP é protegido por uma chave de API ou token bearer.
+
+<Frame>
+    <img src="/images/enterprise/custom-mcp-auth-token.png" alt="Servidor MCP Personalizado com Token de Autenticação" />
+</Frame>
+
+| Campo | Obrigatório | Descrição |
+|-------|-------------|-----------|
+| **Header Name** | Sim | O nome do header HTTP que carrega o token (ex.: `X-API-Key`, `Authorization`). |
+| **Value** | Sim | Sua chave de API ou token bearer. |
+| **Add to** | Não | Onde anexar a credencial — **Header** (padrão) ou **Query parameter**. |
+
+<Tip>
+Se seu servidor espera um token `Bearer` no header `Authorization`, defina o Header Name como `Authorization` e o Value como `Bearer <seu-token>`.
+</Tip>
+
+### OAuth 2.0
+
+Use este método para servidores MCP que requerem autorização OAuth 2.0. O CrewAI gerenciará todo o fluxo OAuth, incluindo a renovação de tokens.
+
+<Frame>
+    <img src="/images/enterprise/custom-mcp-oauth.png" alt="Servidor MCP Personalizado com OAuth 2.0" />
+</Frame>
+
+| Campo | Obrigatório | Descrição |
+|-------|-------------|-----------|
+| **Redirect URI** | — | Preenchido automaticamente e somente leitura. Copie esta URI e registre-a como URI de redirecionamento autorizada no seu provedor OAuth. |
+| **Authorization Endpoint** | Sim | A URL para onde os usuários são enviados para autorizar o acesso (ex.: `https://auth.example.com/oauth/authorize`). |
+| **Token Endpoint** | Sim | A URL usada para trocar o código de autorização por um token de acesso (ex.: `https://auth.example.com/oauth/token`). |
+| **Client ID** | Sim | O Client ID OAuth emitido pelo seu provedor. |
+| **Client Secret** | Não | O Client Secret OAuth. Não é necessário para clientes públicos usando PKCE. |
+| **Scopes** | Não | Lista de escopos separados por espaço a solicitar (ex.: `read write`). |
+| **Token Auth Method** | Não | Como as credenciais do cliente são enviadas ao trocar tokens — **Standard (POST body)** ou **Basic Auth (header)**. Padrão é Standard. |
+| **PKCE Supported** | Não | Ative se seu provedor OAuth suporta Proof Key for Code Exchange. Recomendado para maior segurança. |
+
+<Info>
+**Discover OAuth Config**: Se seu provedor OAuth suporta OpenID Connect Discovery, clique no link **Discover OAuth Config** para preencher automaticamente os endpoints de autorização e token a partir da URL `/.well-known/openid-configuration` do provedor.
+</Info>
+
+#### Configurando OAuth 2.0 Passo a Passo
+
+<Steps>
+    <Step title="Registre a URI de redirecionamento">
+        Copie a **Redirect URI** exibida no formulário e adicione-a como URI de redirecionamento autorizada nas configurações do seu provedor OAuth.
+    </Step>
+
+    <Step title="Insira os endpoints e credenciais">
+        Preencha o **Authorization Endpoint**, **Token Endpoint**, **Client ID** e, opcionalmente, o **Client Secret** e **Scopes**.
+    </Step>
+
+    <Step title="Configure o método de troca de tokens">
+        Selecione o **Token Auth Method** apropriado. A maioria dos provedores usa o padrão **Standard (POST body)**. Alguns provedores mais antigos requerem **Basic Auth (header)**.
+    </Step>
+
+    <Step title="Ative o PKCE (recomendado)">
+        Marque **PKCE Supported** se seu provedor suporta. O PKCE adiciona uma camada extra de segurança ao fluxo de código de autorização e é recomendado para todas as novas integrações.
+    </Step>
+
+    <Step title="Crie e autorize">
+        Clique em **Create MCP Server**. Você será redirecionado ao seu provedor OAuth para autorizar o acesso. Uma vez autorizado, o CrewAI armazenará os tokens e os renovará automaticamente conforme necessário.
+    </Step>
+</Steps>
+
+## Usando Seu Servidor MCP Personalizado
+
+Uma vez conectado, as ferramentas do seu servidor MCP personalizado aparecem junto com as conexões integradas na página **Tools & Integrations**. Você pode:
+
+- **Atribuir ferramentas a agentes** nas suas crews, assim como qualquer outra ferramenta CrewAI.
+- **Gerenciar visibilidade** para controlar quais membros da equipe podem usar o servidor.
+- **Editar ou remover** a conexão a qualquer momento na lista de Connections.
+
+<Warning>
+Se seu servidor MCP ficar inacessível ou as credenciais expirarem, as chamadas de ferramentas usando esse servidor falharão. Certifique-se de que a URL do servidor seja estável e as credenciais estejam atualizadas.
+</Warning>

+title: Ferramentas de Codificação
+description: Use o AGENTS.md para guiar agentes de codificação e IDEs em seus projetos CrewAI.
+icon: terminal
+mode: "wide"
+---
+
+## Por que AGENTS.md
+
+`AGENTS.md` é um arquivo de instruções leve e local do repositório que fornece aos agentes de codificação orientações consistentes e específicas do projeto. Mantenha-o na raiz do projeto e trate-o como a fonte da verdade para como você deseja que os assistentes trabalhem: convenções, comandos, notas de arquitetura e proteções.
+
+## Criar um Projeto com o CLI
+
+Use o CLI do CrewAI para criar a estrutura de um projeto, e o `AGENTS.md` será automaticamente adicionado na raiz.
+
+```bash
+# Crew
+crewai create crew my_crew
+
+# Flow
+crewai create flow my_flow
+
+# Tool repository
+crewai tool create my_tool
+```
+
+## Configuração de Ferramentas: Direcione Assistentes para o AGENTS.md
+
+### Codex
+
+O Codex pode ser guiado por arquivos `AGENTS.md` colocados no seu repositório. Use-os para fornecer contexto persistente do projeto, como convenções, comandos e expectativas de fluxo de trabalho.
+
+### Claude Code
+
+O Claude Code armazena a memória do projeto em `CLAUDE.md`. Você pode inicializá-lo com `/init` e editá-lo usando `/memory`. O Claude Code também suporta importações dentro do `CLAUDE.md`, então você pode adicionar uma única linha como `@AGENTS.md` para incluir as instruções compartilhadas sem duplicá-las.
+
+Você pode simplesmente usar:
+
+```bash
+mv AGENTS.md CLAUDE.md
+```
+
+### Gemini CLI e Google Antigravity
+
+O Gemini CLI e o Antigravity carregam um arquivo de contexto do projeto (padrão: `GEMINI.md`) da raiz do repositório e diretórios pais. Você pode configurá-lo para ler o `AGENTS.md` em vez disso (ou além) definindo `context.fileName` nas configurações do Gemini CLI. Por exemplo, defina apenas para `AGENTS.md`, ou inclua tanto `AGENTS.md` quanto `GEMINI.md` se quiser manter o formato de cada ferramenta.
+
+Você pode simplesmente usar:
+
+```bash
+mv AGENTS.md GEMINI.md
+```
+
+### Cursor
+
+O Cursor suporta `AGENTS.md` como arquivo de instruções do projeto. Coloque-o na raiz do projeto para fornecer orientação ao assistente de codificação do Cursor.
+
+### Windsurf
+
+O Claude Code fornece uma integração oficial com o Windsurf. Se você usa o Claude Code dentro do Windsurf, siga a orientação do Claude Code acima e importe o `AGENTS.md` a partir do `CLAUDE.md`.
+
+Se você está usando o assistente nativo do Windsurf, configure o recurso de regras ou instruções do projeto (se disponível) para ler o `AGENTS.md` ou cole o conteúdo diretamente.

+title: Publicar Ferramentas Personalizadas
+description: Como construir, empacotar e publicar suas próprias ferramentas compatíveis com CrewAI no PyPI para que qualquer usuário do CrewAI possa instalá-las e usá-las.
+icon: box-open
+mode: "wide"
+---
+
+## Visão Geral
+
+O sistema de ferramentas do CrewAI foi projetado para ser extensível. Se você construiu uma ferramenta que pode beneficiar outros, pode empacotá-la como uma biblioteca Python independente, publicá-la no PyPI e disponibilizá-la para qualquer usuário do CrewAI — sem necessidade de PR para o repositório do CrewAI.
+
+Este guia percorre todo o processo: implementação do contrato de ferramentas, estruturação do pacote e publicação no PyPI.
+
+<Note type="info" title="Não pretende publicar?">
+Se você precisa apenas de uma ferramenta personalizada para seu próprio projeto, consulte o guia [Criar Ferramentas Personalizadas](/pt-BR/learn/create-custom-tools).
+</Note>
+
+## O Contrato de Ferramentas
+
+Toda ferramenta CrewAI deve satisfazer uma das duas interfaces:
+
+### Opção 1: Subclassificar `BaseTool`
+
+Subclassifique `crewai.tools.BaseTool` e implemente o método `_run`. Defina `name`, `description` e, opcionalmente, um `args_schema` para validação de entrada.
+
+```python
+from crewai.tools import BaseTool
+from pydantic import BaseModel, Field
+
+
+class GeolocateInput(BaseModel):
+    """Esquema de entrada para GeolocateTool."""
+    address: str = Field(..., description="O endereço para geolocalizar.")
+
+
+class GeolocateTool(BaseTool):
+    name: str = "Geolocate"
+    description: str = "Converte um endereço em coordenadas de latitude/longitude."
+    args_schema: type[BaseModel] = GeolocateInput
+
+    def _run(self, address: str) -> str:
+        # Sua implementação aqui
+        return f"40.7128, -74.0060"
+```
+
+### Opção 2: Usar o Decorador `@tool`
+
+Para ferramentas mais simples, o decorador `@tool` transforma uma função em uma ferramenta CrewAI. A função **deve** ter uma docstring (usada como descrição da ferramenta) e anotações de tipo.
+
+```python
+from crewai.tools import tool
+
+
+@tool("Geolocate")
+def geolocate(address: str) -> str:
+    """Converte um endereço em coordenadas de latitude/longitude."""
+    return "40.7128, -74.0060"
+```
+
+### Requisitos Essenciais
+
+Independentemente da abordagem escolhida, sua ferramenta deve:
+
+- Ter um **`name`** — um identificador curto e descritivo.
+- Ter uma **`description`** — informa ao agente quando e como usar a ferramenta. Isso afeta diretamente a qualidade do uso da ferramenta pelo agente, então seja claro e específico.
+- Implementar **`_run`** (BaseTool) ou fornecer um **corpo de função** (@tool) — a lógica de execução síncrona.
+- Usar **anotações de tipo** em todos os parâmetros e valores de retorno.
+- Retornar um resultado em **string** (ou algo que possa ser convertido de forma significativa).
+
+### Opcional: Suporte Assíncrono
+
+Se sua ferramenta realiza operações de I/O, implemente `_arun` para execução assíncrona:
+
+```python
+class GeolocateTool(BaseTool):
+    name: str = "Geolocate"
+    description: str = "Converte um endereço em coordenadas de latitude/longitude."
+
+    def _run(self, address: str) -> str:
+        # Implementação síncrona
+        ...
+
+    async def _arun(self, address: str) -> str:
+        # Implementação assíncrona
+        ...
+```
+
+### Opcional: Validação de Entrada com `args_schema`
+
+Defina um modelo Pydantic como seu `args_schema` para obter validação automática de entrada e mensagens de erro claras. Se não fornecer um, o CrewAI irá inferi-lo da assinatura do seu método `_run`.
+
+```python
+from pydantic import BaseModel, Field
+
+
+class TranslateInput(BaseModel):
+    """Esquema de entrada para TranslateTool."""
+    text: str = Field(..., description="O texto a ser traduzido.")
+    target_language: str = Field(
+        default="en",
+        description="Código de idioma ISO 639-1 para o idioma de destino.",
+    )
+```
+
+Esquemas explícitos são recomendados para ferramentas publicadas — produzem melhor comportamento do agente e documentação mais clara para seus usuários.
+
+### Opcional: Variáveis de Ambiente
+
+Se sua ferramenta requer chaves de API ou outra configuração, declare-as com `env_vars` para que os usuários saibam o que configurar:
+
+```python
+from crewai.tools import BaseTool, EnvVar
+
+
+class GeolocateTool(BaseTool):
+    name: str = "Geolocate"
+    description: str = "Converte um endereço em coordenadas de latitude/longitude."
+    env_vars: list[EnvVar] = [
+        EnvVar(
+            name="GEOCODING_API_KEY",
+            description="Chave de API para o serviço de geocodificação.",
+            required=True,
+        ),
+    ]
+
+    def _run(self, address: str) -> str:
+        ...
+```
+
+## Estrutura do Pacote
+
+Estruture seu projeto como um pacote Python padrão. Layout recomendado:
+
+```
+crewai-geolocate/
+├── pyproject.toml
+├── LICENSE
+├── README.md
+└── src/
+    └── crewai_geolocate/
+        ├── __init__.py
+        └── tools.py
+```
+
+### `pyproject.toml`
+
+```toml
+[project]
+name = "crewai-geolocate"
+version = "0.1.0"
+description = "Uma ferramenta CrewAI para geolocalizar endereços."
+requires-python = ">=3.10"
+dependencies = [
+    "crewai",
+]
+
+[build-system]
+requires = ["hatchling"]
+build-backend = "hatchling.build"
+```
+
+Declare `crewai` como dependência para que os usuários obtenham automaticamente uma versão compatível.
+
+### `__init__.py`
+
+Re-exporte suas classes de ferramenta para que os usuários possam importá-las diretamente:
+
+```python
+from crewai_geolocate.tools import GeolocateTool
+
+__all__ = ["GeolocateTool"]
+```
+
+### Convenções de Nomenclatura
+
+- **Nome do pacote**: Use o prefixo `crewai-` (ex.: `crewai-geolocate`). Isso torna sua ferramenta fácil de encontrar no PyPI.
+- **Nome do módulo**: Use underscores (ex.: `crewai_geolocate`).
+- **Nome da classe da ferramenta**: Use PascalCase terminando em `Tool` (ex.: `GeolocateTool`).
+
+## Testando sua Ferramenta
+
+Antes de publicar, verifique se sua ferramenta funciona dentro de uma crew:
+
+```python
+from crewai import Agent, Crew, Task
+from crewai_geolocate import GeolocateTool
+
+agent = Agent(
+    role="Analista de Localização",
+    goal="Encontrar coordenadas para os endereços fornecidos.",
+    backstory="Um especialista em dados geoespaciais.",
+    tools=[GeolocateTool()],
+)
+
+task = Task(
+    description="Encontre as coordenadas de 1600 Pennsylvania Avenue, Washington, DC.",
+    expected_output="A latitude e longitude do endereço.",
+    agent=agent,
+)
+
+crew = Crew(agents=[agent], tasks=[task])
+result = crew.kickoff()
+print(result)
+```
+
+## Publicando no PyPI
+
+Quando sua ferramenta estiver testada e pronta:
+
+```bash
+# Construir o pacote
+uv build
+
+# Publicar no PyPI
+uv publish
+```
+
+Se é sua primeira vez publicando, você precisará de uma [conta no PyPI](https://pypi.org/account/register/) e um [token de API](https://pypi.org/help/#apitoken).
+
+### Após a Publicação
+
+Os usuários podem instalar sua ferramenta com:
+
+```bash
+pip install crewai-geolocate
+```
+
+Ou com uv:
+
+```bash
+uv add crewai-geolocate
+```
+
+E então usá-la em suas crews:
+
+```python
+from crewai_geolocate import GeolocateTool
+
+agent = Agent(
+    role="Analista de Localização",
+    tools=[GeolocateTool()],
+    # ...
+)
+```

 # CodeInterpreterTool
 
 ## Description
-This tool is used to give the Agent the ability to run code (Python3) from the code generated by the Agent itself. The code is executed in a sandboxed environment, so it is safe to run any code.
+This tool is used to give the Agent the ability to run code (Python3) from the code generated by the Agent itself. The code is executed in a Docker container for secure isolation.
 
-It is incredible useful since it allows the Agent to generate code, run it in the same environment, get the result and use it to make decisions.
+It is incredibly useful since it allows the Agent to generate code, run it in an isolated environment, get the result and use it to make decisions.
+
+## ⚠️ Security Requirements
+
+**Docker is REQUIRED** for safe code execution. The tool will refuse to execute code without Docker to prevent security vulnerabilities.
+
+### Why Docker is Required
+
+Previous versions included a "restricted sandbox" fallback when Docker was unavailable. This has been **removed** due to critical security vulnerabilities:
+
+- The Python-based sandbox could be escaped via object introspection
+- Attackers could recover the original `__import__` function and access any module
+- This allowed arbitrary command execution on the host system
+
+**Docker provides real process isolation** and is the only secure way to execute untrusted code.
 
 ## Requirements
 
-- Docker
+- **Docker (REQUIRED)** - Install from [docker.com](https://docs.docker.com/get-docker/)
 
 ## Installation
 Install the crewai_tools package

+### Manual Docker Host Configuration
+
+If it is difficult to connect to the Docker daemon automatically (especially for macOS users), you can set up the Docker host manually:
 
 ```python 
 from crewai_tools import CodeInterpreterTool
 
 Agent(

-    tools=[CodeInterpreterTool(user_docker_base_url="<Docker Host Base Url>",
-        user_dockerfile_path="<Dockerfile_path>")],

+        user_dockerfile_path="<Dockerfile_path>"
+    )],
 )
-
 ```
+
+### Unsafe Mode (NOT RECOMMENDED)
+
+If you absolutely cannot use Docker and **fully trust the code source**, you can use unsafe mode:
+
+```python
+from crewai_tools import CodeInterpreterTool
+
+# WARNING: Only use with fully trusted code!
+Agent(
+    ...
+    tools=[CodeInterpreterTool(unsafe_mode=True)],
+)
+```
+
+**⚠️ SECURITY WARNING:** `unsafe_mode=True` executes code directly on the host without any isolation. Only use this if:
+- You completely trust the code being executed
+- You understand the security risks
+- You cannot install Docker in your environment
+
+For production use, **always use Docker** (the default mode).

+
+    This allows users to customize the planning behavior including prompts,

+    level that controls post-step observation and replanning behavior.
+
+    Note: To disable planning, don't pass a planning_config or set planning=False

+
+    Attributes:
+        reasoning_effort: Controls observation and replanning after each step.
+            - "low": Observe each step (validates success), but skip the
+              decide/replan/refine pipeline. Steps are marked complete and
+              execution continues linearly. Fastest option.
+            - "medium": Observe each step. On failure, trigger replanning.
+              On success, skip refinement and continue. Balanced option.
+            - "high": Full observation pipeline — observe every step, then
+              route through decide_next_action which can trigger early goal
+              achievement, full replanning, or lightweight refinement.
+              Most adaptive but adds latency per step.
+        max_attempts: Maximum number of planning refinement attempts.
+            If None, will continue until the agent indicates readiness.
+        max_steps: Maximum number of steps in the generated plan.
+        system_prompt: Custom system prompt for planning. Uses default if None.
+        plan_prompt: Custom prompt for creating the initial plan.
+        refine_prompt: Custom prompt for refining the plan.
+        llm: LLM to use for planning. Uses agent's LLM if None.
