You can run a remote MCP server on Cloudflare Workers that serves tools to MCP clients without requiring authentication. This setup lets you deploy an MCP server, connect from an MCP client or playground, and use your tools remotely via SSE endpoints.

How to use

Connect your MCP client to the remote server to start using your tools. You can access the server through a public SSE endpoint or run a local proxy to reach it.

Connect from the Cloudflare AI Playground to experiment with your MCP server tools directly in a hosted environment:

1. Open the Cloudflare AI Playground at https://playground.ai.cloudflare.com/ and enter your deployed MCP server URL (remote-mcp-server-authless.<your-account>.workers.dev/sse). 2. Once connected, you can invoke your MCP tools from the playground interface.

If you prefer to run and use tools from a local client, you can connect Claude Desktop to your remote server via the mcp-remote proxy. Use the following configuration in Claude Desktop under Settings > Developer > Edit Config to point to your server. This enables you to access remote tools as if they were local.
