fix: enhance LLM response handling and serialization (#4909)

* fix: enhance LLM response handling and serialization

* Updated the Flow class to improve error handling when both structured and simple prompting fail, ensuring the first outcome is returned as a fallback.
* Introduced a new function, _serialize_llm_for_context, to properly serialize LLM objects with provider prefixes for better context management.
* Added tests to validate the new serialization logic and ensure correct behavior when LLM calls fail.

This update enhances the robustness of LLM interactions and improves the overall flow of handling outcomes.

* fix: patch VCR response handling to prevent httpx.ResponseNotRead errors (#4917)

* fix: enhance LLM response handling and serialization

* Updated the Flow class to improve error handling when both structured and simple prompting fail, ensuring the first outcome is returned as a fallback.
* Introduced a new function, _serialize_llm_for_context, to properly serialize LLM objects with provider prefixes for better context management.
* Added tests to validate the new serialization logic and ensure correct behavior when LLM calls fail.

This update enhances the robustness of LLM interactions and improves the overall flow of handling outcomes.

* fix: patch VCR response handling to prevent httpx.ResponseNotRead errors

VCR's _from_serialized_response mocks httpx.Response.read(), which
prevents the response's internal _content attribute from being properly
initialized. When OpenAI's client (using with_raw_response) accesses
response.content, httpx raises ResponseNotRead.

This patch explicitly sets response._content after the response is
created, ensuring that tests using VCR cassettes work correctly with
the OpenAI client's raw response handling.

Fixes tests:
- test_hierarchical_crew_creation_tasks_with_sync_last
- test_conditional_task_last_task_when_conditional_is_false
- test_crew_log_file_output

-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.

+icon: "plug"
+mode: "wide"
+---
+
+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
+
+<CardGroup cols={2}>
+  <Card title="CrewAI AMP Account" icon="user">
+    You need an active [CrewAI AMP](https://app.crewai.com) account.
+  </Card>

+    The URL of the MCP server you want to connect. The server must be accessible from the internet and support Streamable HTTP transport.
+  </Card>
+</CardGroup>
+
+## 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>

+    </Step>
+</Steps>
+
+## 인증 방법
+
+### 인증 없음
+
+MCP 서버가 공개적으로 접근 가능하고 자격 증명이 필요 없을 때 이 옵션을 선택합니다. 오픈 소스 서버나 VPN 뒤에서 실행되는 내부 서버에 일반적입니다.
+
+### 인증 토큰
+
+MCP 서버가 API 키 또는 Bearer 토큰으로 보호되는 경우 이 방법을 사용합니다.
+
+<Frame>
+    <img src="/images/enterprise/custom-mcp-auth-token.png" alt="인증 토큰을 사용하는 커스텀 MCP 서버" />
+</Frame>
+
+| 필드 | 필수 | 설명 |
+|------|------|------|
+| **Header Name** | 예 | 토큰을 전달하는 HTTP 헤더 이름 (예: `X-API-Key`, `Authorization`). |
+| **Value** | 예 | API 키 또는 Bearer 토큰. |
+| **Add to** | 아니오 | 자격 증명을 첨부할 위치 — **Header** (기본값) 또는 **Query parameter**. |
+
+<Tip>
+서버가 `Authorization` 헤더에 `Bearer` 토큰을 예상하는 경우, Header Name을 `Authorization`으로, Value를 `Bearer <토큰>`으로 설정하세요.
+</Tip>
+
+### OAuth 2.0
+
+OAuth 2.0 인증이 필요한 MCP 서버에 이 방법을 사용합니다. CrewAI가 토큰 갱신을 포함한 전체 OAuth 흐름을 처리합니다.
+
+<Frame>
+    <img src="/images/enterprise/custom-mcp-oauth.png" alt="OAuth 2.0을 사용하는 커스텀 MCP 서버" />

+## 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>

+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

+
+### Unsafe Mode (NOT RECOMMENDED)
+
+If you absolutely cannot use Docker and **fully trust the code source**, you can use unsafe mode:

+
+# WARNING: Only use with fully trusted code!
+Agent(

+**⚠️ 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,

+
+    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.
+
+    Example:
+        ```python
