We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.

Overview

What is Building a Remote MCP Server on Cloudflare (Without Auth)?

This server is a template for deploying an MCP (Model Context Protocol) server on Cloudflare Workers without requiring authentication. It allows developers to define custom tools and connect to remote MCP clients like the Cloudflare AI Playground or Claude Desktop via a proxy.

How to use Building a Remote MCP Server on Cloudflare (Without Auth)?

Deploy using the "Deploy to Workers" button or run npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. Customize tools in src/index.ts inside the init() method using this.server.tool(...). Connect clients by providing the deployed SSE URL (e.g., remote-mcp-server-authless.<account>.workers.dev/sse). For Claude Desktop, use the mcp-remote proxy with npx mcp-remote <SSE-URL>.

Key features of Building a Remote MCP Server on Cloudflare (Without Auth)?

  • Deploy to Cloudflare Workers without authentication
  • Add custom tools using this.server.tool(...) inside init()
  • Connect directly to Cloudflare AI Playground as a remote client
  • Access from local MCP clients via the mcp-remote proxy
  • Server URL pattern: <name>.<account>.workers.dev/sse
  • Quick start using a pre‑built Cloudflare template

Use cases of Building a Remote MCP Server on Cloudflare (Without Auth)?

  • Deploying a remote MCP server for testing without auth barriers
  • Using custom MCP tools from the Cloudflare AI Playground
  • Integrating MCP tools with Claude Desktop through a remote proxy
  • Prototyping and iterating on MCP tool definitions on Cloudflare Workers

Frequently asked questions
