# 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. ## Get started: [](https://deploy.workers.cloudflare.com/?url=https://github.com/cloudflare/ai/tree/main/demos/remote-mcp-authless) 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: ```bash npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless ``` ## Customizing your MCP Server To add your own [tools](https://developers.cloudflare.com/agents/model-context-protocol/tools/) to the MCP server, define each tool inside the `init()` method of `src/index.ts` using `this.server.tool(...)`. ## Connect to Cloudflare AI Playground You can connect to your MCP server from the Cloudflare AI Playground, which is a remote MCP client: 1. Go to https://playground.ai.cloudflare.com/ 2. Enter your deployed MCP server URL (`remote-mcp-server-authless.<your-account>.workers.dev/sse`) 3. You can now use your MCP tools directly from the playground! ## Connect Claude Desktop to your MCP server You can also connect to your remote MCP server from local MCP clients, by using the [mcp-remote proxy](https://www.npmjs.com/package/mcp-remote). To connect to your MCP server from Claude Desktop, follow [Anthropic's Quickstart](https://modelcontextprotocol.io/quickstart/user) and within Claude Desktop go to Settings > Developer > Edit Config. Update with this configuration: ```json { "mcpServers": { "calculator": { "command": "npx", "args": [ "mcp-remote", "http://localhost:8787/sse" // or remote-mcp-server-authless.your-account.workers.dev/sse ] } } } ``` Restart Claude and you should see the tools become available.
