# A2A / MCP Protocols

Connect the agent to external tools, data, and other agents over MCP and A2A.

Two protocols extend the agent beyond your own app:

- **MCP** (Model Context Protocol) gives the agent tools and data from an MCP server.
- **A2A** (Agent-to-Agent) lets the agent delegate to, and receive tasks from, other AI agents.

## Where to start
