What does this server do that alternatives don't?
It provides a direct MCP bridge from Claude Desktop to A2A protocol agents, allowing dynamic registration and calling of agents.

基本情報
A2A MCP Server is a lightweight Python bridge that lets Claude Desktop or any MCP client talk to A2A agents. It provides three tools: register servers, list agents, and call an agent, enabling quick integration of A2A-compatible agents with zero boilerplate for rapid prototyping.

A simple MCP server that provides Claude Desktop access to A2A (Agent-to-Agent) protocol agents, particularly those built with a2a_min and fast-agent. It was developed as a personal project to assist with agent development and is intended to be developer friendly rather than production ready.
Use the three MCP tools: a2a_server_registry to register or remove A2A servers, list_agents to list registered agents with capabilities, and call_agent to send a prompt to a specific agent. The typical workflow is to register a server, list agents, then call an agent as needed.
It provides a direct MCP bridge from Claude Desktop to A2A protocol agents, allowing dynamic registration and calling of agents.
It requires an MCP host (like Claude Desktop) and an A2A agent server running on a reachable URL.
No, the README explicitly states it is developer friendly more than production ready, and not the best idea to deploy into prod as-is.
Register an A2A server (e.g., a security audit agent built with fast-agent and a2a_min), list agents, then call one with a prompt.
The README does not mention specific transport or authentication beyond registering servers via URL. It uses MCP's standard tool interface.
