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.

This will deploy your MCP server to a URL like:remote-mcp-server-authless.<your-account>.workers.dev/sse

Alternatively, you can use the command line below to get the remote MCP Server created on your local machine:

npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless

To add your owntoolsto the MCP server, define each tool inside theinit()method ofsrc/index.tsusingthis.server.tool(...).

You can connect to your MCP server from the Cloudflare AI Playground, which is a remote MCP client:
- Go tohttps://playground.ai.cloudflare.com/
- Enter your deployed MCP server URL (remote-mcp-server-authless.<your-account>.workers.dev/sse)
- You can now use your MCP tools directly from the playground!

You can also connect to your remote MCP server from local MCP clients, by using themcp-remote proxy.
