Overview

Workers MCP Server is a proof-of-concept server that allows interaction with Cloudflare Workers using the Model Context Protocol (MCP). It enables users to extend Claude Desktop and other MCP clients by invoking functions through Cloudflare's new RPC syntax.

To use the Workers MCP Server, download Claude Desktop, clone the repository, install dependencies, configure the wrangler.json, deploy the worker, and set up the server alias with the worker URL. Restart Claude Desktop after installation to access the new functionalities.

  • Integration with Cloudflare Workers for enhanced functionality. - Ability to invoke functions using a simple RPC syntax. - Documentation generation for easy reference of available methods.
  1. Generating random numbers through Cloudflare Workers.
  2. Sending emails via the Email Routing API.
  3. Building interactive applications that leverage Cloudflare's capabilities.

Cursor

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

.cursor/mcp.json

{
  "mcpServers": {
    "geelen-workers-mcp-server-mcp-mirror": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-geelen-workers-mcp-server-mcp-mirror"
      ]
    }
  }
}

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": {
    "geelen-workers-mcp-server-mcp-mirror": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-geelen-workers-mcp-server-mcp-mirror"
      ]
    }
  }
}

Claude Code

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

.mcp.json (project root)

{
  "mcpServers": {
    "geelen-workers-mcp-server-mcp-mirror": {
      "command": "npx",
      "args": [
        "-y",

      ]
    }
  }
}

VS Code (Copilot)

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

.vscode/mcp.json

{
  "servers": {
    "geelen-workers-mcp-server-mcp-mirror": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-geelen-workers-mcp-server-mcp-mirror"
      ]
    }
  }
}

Windsurf

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

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "geelen-workers-mcp-server-mcp-mirror": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-geelen-workers-mcp-server-mcp-mirror"
