Overview
CrewAI is an MIT-licensed Python framework for wiring several AI agents into one crew — a researcher, a drafter and an editor that hand work down a chain instead of one model trying to do everything in a single prompt. It is genuinely code-first: you install it with uv, configure model keys and drive it from a CLI, so it suits a marketer paired with a developer rather than a solo non-technical user. Worth being precise about its MCP support, which is widely misread: CrewAI agents *consume* external MCP servers as tools, but CrewAI does not expose itself as an MCP server for another agent to drive.
