Overview
What is Building a Remote MCP Server on Cloudflare (Without Auth)?
This example allows you to deploy a remote MCP server that does not require authentication on Cloudflare Workers. It is intended for developers who want to quickly set up a remote model context protocol server using Cloudflare’s edge network and SSE transport.
How to use Building a Remote MCP Server on Cloudflare (Without Auth)?
Deploy the server by clicking the “Deploy to Workers” button or by running npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. After deployment, customize tools in src/index.ts inside the init() method. Connect clients via the server’s SSE endpoint (e.g., remote-mcp-server-authless.<your-account>.workers.dev/sse).
