# 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.

## Tools

- `get_stories` Fetching (top, new, ask_hn, show_hn) stories
- `get_story_info` Fetching comments associated with a story
- `search_stories` Searching for stories by query
- `get_user_info` Fetching user info

## Example Usage

Use prompts like the following:

```
User: Get the top stories of today
  Output: Uses `get_stories` tool and returns a story about AI
User: What does the details of the story today that talks about the future of AI
  Output: Uses `get_story_info` tool based on the results of the previous tool
User: What has the user `pg` been up to?
  Output: Uses `get_user_info` tool and returns a summary of the user's activity
User: What does hackernews say about careers in AI?
  Output: Uses `search_stories` tool and returns a summary of the comments
```

A more detailed example with the puppeteer MCP server:

```
User: What are the top stories of today?
  Output: Uses `get_stories` tool and returns a story about AI
User: Can you use the puppeteer tool to read the article about <AI> and also use the hackernews tool to view the comments and give me a summary of what the main comments are about the article?
  Output: Uses puppeteer tool to read the article about AI and then uses the `get_story_info` hn tool to get the comments and returns a summary of the comments
```
