Mirrors the LangChain / ADK / OpenAI Agents examples: a single-agent CrewAI crew wired to the e2a MCP surface via `crewai-tools`' MCPServerAdapter, in both stdio and hosted Streamable HTTP variants. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Verified via dry run that the bare deps don't pull the right extras: - `crewai-tools[mcp]` is required for the `mcpadapt` bridge (otherwise `MCPServerAdapter` reports `MCP_AVAILABLE = False`). - `crewai[anthropic]` is required for the native Anthropic provider used by `"anthropic/claude-sonnet-4-6"`. - `email-validator` is needed at runtime because the e2a tool schemas carry email-typed fields that crewai-tools wires through pydantic. With these, both `agent.py` and `agent_hosted.py` cleanly load all 18 e2a tools and reach the LLM call (verified end-to-end against a dummy Anthropic key, which 401s as expected).

Summary
mcp/examples/crewai/mirroring the shape of the LangChain / ADK / OpenAI Agents examples.crewai-tools'MCPServerAdapter.agent.py(stdio vianpx -y @e2a/mcp-server) andagent_hosted.py(Streamable HTTP tohttps://mcp.e2a.dev/mcp).mcp/examples/README.mdindex gets a CrewAI row.Why
We have working examples + upstream docs PRs for ADK (merged, google/adk-docs#1793) and LangChain (open, langchain-ai/docs#4150). CrewAI is the next-most-trafficked Python agent framework with a third-party tools integration index — adding the example here unblocks the corresponding upstream docs PR.
