# A2A Bridge

> Use this tool when you need to enable seamless communication between Claude Desktop and A2A protocol agents, or to extend Claude's capabilities by interacting with external agents. The A2A Bridge takes in A2A server registrations, agent listings, and prompts as inputs, and outputs agent capabilities and responses. It solves problems of agent compatibility and integration, and is ideal for use cases involving multi-agent interactions and development.

## Description

The A2A MCP Server bridges Claude Desktop with A2A (Agent-to-Agent) protocol agents, enabling seamless communication between them. Built as a personal project for agent development, it provides three key tools: registering A2A servers, listing available agents with their capabilities, and calling agents with prompts. The server has been tested with security audit agents built on fast-agent and a2a_min, extending Claude's capabilities by allowing it to interact with any A2A-compatible agent through the MCP tools interface.
