Cloudflare Remote MCP Server

Example Use Cases

• 1

  Expose custom tools (calculators, data lookups, etc.) via an MCP server without requiring authentication so tools can be accessed from remote clients.

• 2

  Integrate with the Cloudflare AI Playground to test or demo tool-enabled agent workflows via a hosted SSE endpoint.

• 3

  Connect local MCP clients (e.g., Claude Desktop) to a remote MCP server using the mcp-remote proxy for development or testing.

Description

This repository is an example template to deploy a remote MCP server on Cloudflare Workers that does not require authentication. It lets you define and register custom tools inside the init() method (using this.server.tool(...)) and exposes an SSE endpoint (e.g., /sse) for MCP clients. You can connect it to the Cloudflare AI Playground or local clients (like Claude Desktop) via the mcp-remote proxy. The example includes both a direct Workers deploy button and local project scaffolding instructions.
