🔗 Connect to AI Agents

Add your server to your MCP configuration so AI agents can use it:

For Claude Desktop

Create or update ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "my-app": {
      "command": "python",
      "args": ["/path/to/your/server.py"]
    }
  }
}

For VS Code

Create or update .vscode/mcp.json in your workspace:

{
  "mcpServers": {
    "my-app": {
      "command": "python",
      "args": ["/path/to/your/server.py"]
    }
  }
}

For Other MCP Clients

Most MCP clients look for a mcp.json file in:

• ~/.mcp.json (global)
• ./mcp.json (project-specific)
• Or their own configuration location

Example configuration:

{
  "mcpServers": {
    "fastestmcp-server": {
      "command": "python",
      "args": ["server.py"],
      "cwd": "/path/to/your/project"
    }
  }
}

Restart your MCP client after updating the configuration!
