Overview
CrewAI is an MIT-licensed Python framework for wiring several agents into one crew: a researcher, a drafter and an editor passing work down a chain instead of one prompt doing everything. It's code-first and driven from a CLI, so it suits a marketer paired with a developer. Its agents consume external MCP servers, but CrewAI isn't one.
Key Features
- ✓MIT-licensed Python SDK for multi-agent crews
- ✓Documented CLI for local development and deployment
- ✓Consumes external MCP servers as agent tools (client-side)
- ✓Model-agnostic — bring your own LLM keys
- ✓Free tier with 50 workflow executions per month
