# A2A MCP Server
A simple MCP server that provides Claude Desktop access to A2A protocol agents.
> Developer friendly more than production ready, you can hack it to adapt to your needs and expand on whatever you need.
> But probably not the best idea to deploy into prod as-is.
## Overview
This project was created to connect Claude Desktop with A2A (Agent-to-Agent) protocol agents, particularly those built with pcingola/a2a_min and fast-agent. It was developed as a personal project to assist with agent development and for fun.
## Tools
The server provides three MCP tools:
1. **a2a_server_registry** - Register or remove A2A servers
```
{
"action": "add",
"name": "security_audit",
"url": "http://localhost:8000"
}
```
2. **list_agents** - List all registered agents with their capabilities
```
{}
```
3. **call_agent** - Send a prompt to an agent and get its response
```
{
"agent_name": "security_audit",
"prompt": "regismesquita/DevControlMCP"
}
```
## Workflow
The typical workflow is:
1. Register an A2A server with `a2a_server_registry`
2. List available agents with `list_agents`
3. Call an agent with `call_agent` whenever needed
## Local Testing
This server has been tested locally with a security audit agent built on fast-agent and a2a_min. It successfully enables Claude Desktop to communicate with A2A agents.
## Purpose
This bridge allows Claude Desktop to interact with any A2A-compatible agent, extending Claude's capabilities through the MCP tools interface.
