Catalog onlyCatalog onlySTDIO

Overview

FastMCP is a user-friendly framework designed to simplify the creation of Model Context Protocol (MCP) servers, allowing for the easy integration of data and functionality with language models.

To utilize FastMCP, you define your tools and resources in a Python script and run your server with the provided CLI commands. Installation can be done via pip, and you can quickly deploy your server using specific commands for development and production environments.

  • Fast: Streamlined code for rapid development. - Simple: Minimal boilerplate required to set up MCP servers. - Pythonic: Intuitive design that fits seamlessly into Python programming paradigms. - Comprehensive: Aims to cover all aspects of the MCP specification, enabling robust server development.
  1. Building custom tools and data access methods for language models.
  2. Integrating databases and functionalities into LLM applications seamlessly.
  3. Developing interactive applications that leverage language model capabilities through predefined prompts.

Use these steps to connect FastMCP in Cursor, Claude, VS Code, and other MCP-compatible apps. The same JSON appears in the Use with menu above for one-click copy.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "fastmcp-punkpeye": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-fastmcp-punkpeye"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "fastmcp-punkpeye": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-fastmcp-punkpeye"
      ]
    }
  }
}

Claude Code

Add this to your project's .mcp.json file. Claude Code will detect it automatically.

.mcp.json (project root)

{
  "mcpServers": {
    "fastmcp-punkpeye": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-fastmcp-punkpeye"
      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
  "servers": {
    "fastmcp-punkpeye": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-fastmcp-punkpeye"
      ]
    }
  }
}

Windsurf

Add this to your Windsurf MCP config file, then restart Windsurf.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "fastmcp-punkpeye": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-fastmcp-punkpeye"
      ]
    }
  }
}

Cline

Open Cline settings, navigate to MCP Servers, and add this server configuration.

Cline MCP Settings (via UI)

{
  "mcpServers": {
    "fastmcp-punkpeye": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-fastmcp-punkpeye"
      ]
    }
  }
}
