Building a Remote MCP Server on Cloudflare (Without Auth)

What is Building a Remote MCP Server on Cloudflare (Without Auth)?

This example allows you to deploy a remote MCP server that doesn't require authentication on Cloudflare Workers. It is intended for developers who want a quick, no-auth MCP server integrated with Cloudflare's serverless platform.

How to use Building a Remote MCP Server on Cloudflare (Without Auth)?

Deploy using the "Deploy to Workers" button, which creates a URL like remote-mcp-server-authless.<your-account>.workers.dev/sse. Alternatively, run npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. Customize tools inside the init() method of src/index.ts using this.server.tool(...). Connect remote clients via SSE—Cloudflare AI Playground accepts the deployed URL directly; for local clients like Claude Desktop, use the mcp-remote proxy.
