Installation

This project uses uv for package management and just for task running. Make sure you have both installed:

# Install uv if you don't have it
curl -LsSf https://astral.sh/uv/install.sh | sh

# Install just if you don't have it
# On macOS with Homebrew:
brew install just
# Or with cargo:
cargo install just

Then build the project:

Usage

Running the MCP Server

To start the MCP agents server:

just run

Using with MCP Clients

You can use this server with any MCP-compatible client. The configuration depends on how you want to run the server:

Option 1: Local Development (using source code)

For development or when running from a local clone:

{
  "mcpServers": {
    "mcp-agents": {
      "command": "uv",
      "args": ["run", "mcp-agents"],
      "cwd": "/Users/means/repository/mcp-agents",
      "env": {}
    }
  }
}

Option 2: PyPI Installation (recommended for end users)

Once published to PyPI, users can use this simpler configuration:

{
  "mcpServers": {
    "mcp-agents": {
      "command": "uvx",
      "args": ["amajakai14_mcp-agents"]
    }
  }
}

Alternative with pipx:

{
  "mcpServers": {
    "mcp-agents": {
      "command": "pipx",
      "args": ["run", "amajakai14_mcp-agents"]
    }
  }
}

Option 3: Version Pinning

To pin to a specific version:

{
  "mcpServers": {
    "mcp-agents": {
      "command": "uvx",
      "args": ["amajakai14_mcp-agents==0.1.0"]
    }
  }
}

For Claude Desktop

Add any of the above configurations to your Claude Desktop config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%/Claude/claude_desktop_config.json

Testing the Tools

Run the test script to verify the tools work correctly:

Adding New Tools

To add new tools using FastMCP:

1. Add a new function with the @mcp.tool() decorator:

   @mcp.tool("tool_name", description="Description of what the tool does")
   def tool_name(param1: type, param2: type) -> return_type:
       # Tool implementation
       return result
   

2. Update the README with documentation for the new tool
