## Before you call it

1. Set CREWAI_DISABLE_TELEMETRY=true before the first run
2. Put MCP keys in headers, not in the URL as the docs' Exa example does
3. Pin a stable version. Development builds share the crewai name on PyPI
4. Add a PRE_TOOL_CALL hook for any tool that writes or sends
5. Check the logs for MCP connection warnings. A failed server doesn't stop the agent

## Connect

```bash
pip install crewai
```
