Lucas Gomide a237ebabba feat: adopt directory-based docs versioning with Edge channel (#6202)
* feat: adopt directory-based docs versioning with Edge channel

Switch docs.crewai.com from navigation-only versioning (every version
selector entry rendered the same docs/<lang>/* source files) to
Mintlify's directory-based versioning so each version selector entry
renders its own snapshot. Add an "Edge" channel under docs/edge/<lang>/*
that always reflects main HEAD for unreleased work, eliminating
pre-release leakage onto frozen release labels. External links to
canonical /<lang>/* URLs are preserved via wildcard redirects that
always land on the current default version.

Layout:
- docs/edge/<lang>/*         rolling source (you edit here)
- docs/edge/enterprise-api.*.yaml
- docs/v<X.Y.Z>/<lang>/*     frozen, immutable snapshots
- docs/v<X.Y.Z>/enterprise-api.*.yaml
- docs/images/               shared, append-only
- docs/docs.json             nav + redirects

URLs follow the Mintlify-idiomatic shape: /edge/<lang>/<page> for
Edge, /v<X.Y.Z>/<lang>/<page> for every frozen snapshot. The wildcard
redirects /<lang>/:slug* -> /<default>/<lang>/:slug* keep stale links
working, and every freeze rewrites them (plus all per-section/per-page
redirects) so destinations always resolve to the current default
without depending on a second redirect hop.

Release flow integration (devtools release):
- New module crewai_devtools.docs_versioning.freeze() materialises
  docs/v<X.Y.Z>/ from docs/edge/, rewrites openapi: refs inside the
  snapshot, inserts the version into every language block in
  docs.json, and refreshes all redirect destinations.
- _update_docs_and_create_pr() in cli.py now calls that freeze during
  Phase 2 of devtools release. Edge changelogs are updated first (so
  the snapshot freeze picks them up), then the snapshot is staged
  alongside docs.json, branched as docs/freeze-v<X.Y.Z>, and the PR
  is titled [docs-freeze] docs: snapshot and changelog for v<X.Y.Z>
  — the title prefix the new CI guard reads.
- The PR still gates tag, GitHub release, PyPI publish, and the
  enterprise release as before; no new PRs are added.
- Pre-releases (1.X.YaN, 1.X.YbN, ...) skip the snapshot — they ride
  Edge — and the docs PR title omits the [docs-freeze] prefix.
- docs_check (AI-generated docs scaffolding) writes to
  docs/edge/<lang>/* so newly-generated unreleased docs land in Edge
  and never accidentally touch a frozen snapshot.

Migration scripts (one-shot):
- scripts/docs/freeze_historical_versions.py reconstructs all 16
  historical snapshots (v1.10.0 .. v1.14.7) from git tags via
  git archive | tar, rewriting openapi: MDX refs so each snapshot
  reads its own enterprise-api YAML rather than the live one.
- scripts/docs/prefix_version_paths.py one-shot-migrates docs.json:
  rewrites every page path in 16 versioned blocks to point under
  docs/v<X.Y.Z>/, inserts a new Edge entry per language, tags
  v1.14.7 as Latest (default), prunes pages whose target file
  doesn't exist in the snapshot (e.g. docs/ar/ didn't exist before
  v1.12.0), and writes the wildcard + per-section redirects.
- scripts/docs/freeze_current_edge.py is now a thin CLI wrapper
  around docs_versioning.freeze for manual one-off freezes (e.g.
  retroactively snapshotting a forgotten release).

CI guards (.github/workflows/docs-snapshots.yml):
- Frozen snapshots under docs/v[0-9]*/ are immutable; only PRs whose
  title contains [docs-freeze] (i.e. release-cut PRs generated by
  devtools release or the manual wrapper) may modify them.
- Images under docs/images/ are append-only since snapshots share a
  single image directory. Deleting or renaming an image breaks every
  historical snapshot that still references it.

Restored docs/images/crewai-otel-export.png from PR #3673; it was
deleted in PR #4908 but v1.10.0 / v1.10.1 snapshots still reference
it. Restoring instead of editing the snapshots preserves historical
rendering fidelity and validates the new append-only rule
retroactively.

Tests:
- lib/devtools/tests/test_docs_versioning.py covers the freeze: file
  copy, openapi rewrite, version insertion, default demotion, redirect
  upserts, per-section redirect rewriting, idempotency, and invalid
  inputs.

Verified locally with mintlify broken-links: 0 broken links across
the full site (Edge + 16 frozen versions, 4 locales).

AGENTS.md (repo root) is the contributor guide for the new model;
RELEASING.md is the release-cut runbook; README's Contribution
section links to both.

title: Transporte HTTP Streamable
description: Saiba como conectar o CrewAI a servidores MCP remotos usando o transporte HTTP Streamable flexível.
icon: globe
mode: "wide"
---
## Visão Geral
O transporte HTTP Streamable oferece uma maneira flexível de se conectar a servidores MCP remotos. Ele é frequentemente baseado em HTTP e pode suportar vários padrões de comunicação, incluindo requisição-resposta e streaming, às vezes utilizando Server-Sent Events (SSE) para fluxos do servidor para o cliente dentro de uma interação HTTP mais ampla.
## Conceitos-Chave
- **Servidores Remotos**: Projetado para servidores MCP hospedados remotamente.
- **Flexibilidade**: Pode suportar padrões de interação mais complexos do que SSE puro, potencialmente incluindo comunicação bidirecional se o servidor implementá-la.
- **Configuração do `MCPServerAdapter`**: Você precisará fornecer a URL base do servidor para comunicação MCP e especificar `"streamable-http"` como o tipo de transporte.
## Conectando via HTTP Streamable
Você tem dois métodos principais para gerenciar o ciclo de vida da conexão com um servidor MCP HTTP Streamable:
### 1. Conexão Totalmente Gerenciada (Recomendado)
A abordagem recomendada é usar um gerenciador de contexto Python (`with` statement), que lida automaticamente com a configuração e encerramento da conexão.
```python
from crewai import Agent, Task, Crew, Process
from crewai_tools import MCPServerAdapter
server_params = {
"url": "http://localhost:8001/mcp", # Replace with your actual Streamable HTTP server URL
"transport": "streamable-http"
}
try:
with MCPServerAdapter(server_params) as tools:
print(f"Available tools from Streamable HTTP MCP server: {[tool.name for tool in tools]}")
agente_http = Agent(
role="Integrador de Serviços HTTP",
goal="Utilizar ferramentas de um servidor MCP remoto via Streamable HTTP.",
backstory="Um agente de IA especializado em interagir com serviços web complexos.",
tools=tools,
verbose=True,
)
http_task = Task(
description="Realizar uma consulta de dados complexa usando uma ferramenta do servidor Streamable HTTP.",
expected_output="O resultado da consulta de dados complexa.",
agent=agente_http,
)
http_crew = Crew(
agents=[agente_http],
tasks=[http_task],
verbose=True,
process=Process.sequential
)
result = http_crew.kickoff()
print("\nCrew Task Result (Streamable HTTP - Managed):\n", result)
except Exception as e:
print(f"Error connecting to or using Streamable HTTP MCP server (Managed): {e}")
print("Ensure the Streamable HTTP MCP server is running and accessible at the specified URL.")
```
**Nota:** Substitua `"http://localhost:8001/mcp"` pela URL real do seu servidor MCP HTTP Streamable.
### 2. Ciclo de Vida da Conexão Manual
Para cenários que exigem controle mais explícito, você pode gerenciar a conexão do `MCPServerAdapter` manualmente.
<Info>
É **crítico** chamar `mcp_server_adapter.stop()` quando terminar para fechar a conexão e liberar recursos. Usar um bloco `try...finally` é a forma mais segura de garantir isso.
</Info>
```python
from crewai import Agent, Task, Crew, Process
from crewai_tools import MCPServerAdapter
server_params = {
"url": "http://localhost:8001/mcp", # Replace with your actual Streamable HTTP server URL
"transport": "streamable-http"
}
mcp_server_adapter = None
try:
mcp_server_adapter = MCPServerAdapter(server_params)
mcp_server_adapter.start()
tools = mcp_server_adapter.tools
print(f"Available tools (manual Streamable HTTP): {[tool.name for tool in tools]}")
manual_http_agent = Agent(
role="Usuário Avançado de Serviços Web",
goal="Interagir com um servidor MCP usando conexões HTTP Streamable gerenciadas manualmente.",
backstory="Um especialista em IA em ajustar integrações baseadas em HTTP.",
tools=tools,
verbose=True
)
data_processing_task = Task(
description="Enviar dados para processamento e recuperar resultados via Streamable HTTP.",
expected_output="Dados processados ou confirmação.",
agent=manual_http_agent
)
data_crew = Crew(
agents=[manual_http_agent],
tasks=[data_processing_task],
verbose=True,
process=Process.sequential
)
result = data_crew.kickoff()
print("\nCrew Task Result (Streamable HTTP - Manual):\n", result)
except Exception as e:
print(f"An error occurred during manual Streamable HTTP MCP integration: {e}")
print("Ensure the Streamable HTTP MCP server is running and accessible.")
finally:
if mcp_server_adapter and mcp_server_adapter.is_connected:
print("Stopping Streamable HTTP MCP server connection (manual)...")
mcp_server_adapter.stop() # **Crucial: Ensure stop is called**
elif mcp_server_adapter:
print("Streamable HTTP MCP server adapter was not connected. No stop needed or start failed.")
```
## Considerações de Segurança
Ao utilizar o transporte HTTP Streamable, as melhores práticas gerais de segurança web são fundamentais:
- **Use HTTPS**: Sempre prefira HTTPS (HTTP Seguro) para as URLs do seu servidor MCP para criptografar os dados em trânsito.
- **Autenticação**: Implemente mecanismos robustos de autenticação se seu servidor MCP expuser ferramentas ou dados sensíveis.
- **Validação de Entrada**: Garanta que seu servidor MCP valide todas as requisições e parâmetros recebidos.
