概要
What is Building a Remote MCP Server on Cloudflare (Without Auth)?
This example lets you deploy a remote MCP (Model Context Protocol) server on Cloudflare Workers without requiring authentication. It is intended for developers who want to expose MCP tools over the internet quickly using a serverless platform.
How to use Building a Remote MCP Server on Cloudflare (Without Auth)?
Deploy the server either by clicking the "Deploy to Workers" button (which creates a URL like remote-mcp-server-authless.<your-account>.workers.dev/sse) or by running npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. To add custom tools, edit src/index.ts inside the init() method using this.server.tool(...). Connect to the server from Cloudflare AI Playground by entering the deployed SSE URL, or from Claude Desktop by using the mcp-remote proxy configured in the Claude Desktop settings.
Key features of Building a Remote MCP Server on Cloudflare (Without Auth)
- Deployed on Cloudflare Workers with no authentication required.
- Customizable MCP tools defined in
src/index.ts. - SSE endpoint exposed at the deployed worker URL.
- Ready to connect with Cloudflare AI Playground as a remote MCP client.
- Works with local MCP clients via the
mcp-remoteproxy. - One‑click deployment from the Cloudflare Workers dashboard.
Use cases of Building a Remote MCP Server on Cloudflare (Without Auth)
- Expose MCP tools publicly on the internet without setting up auth.
- Integrate remote MCP tools into Cloudflare AI Playground for testing.
- Connect a remote MCP server to local desktop clients like Claude Desktop.
- Quickly prototype and deploy MCP tools using a serverless architecture.
