Overview
What is Remote MCP Server on Cloudflare?
A template for deploying a remote MCP (Model Context Protocol) server on Cloudflare Workers with OAuth login. It provides a working example that can be run locally, connected to the MCP Inspector, and integrated with Claude Desktop over SSE transport.
How to use Remote MCP Server on Cloudflare?
Clone the repository, install dependencies with pnpm install, then run locally with npx nx dev remote-mcp-server. Connect using the MCP Inspector (set transport to SSE and URL to http://localhost:8787/sse) or configure Claude Desktop with mcp-remote pointing to the same URL. Deploy to Cloudflare by creating a KV namespace for OAuth and running npm run deploy.
Key features of Remote MCP Server on Cloudflare
- Runs as a Cloudflare Worker with SSE transport
- Includes OAuth login flow for authentication
- Works with MCP Inspector for local testing
- Integrates directly with Claude Desktop via mcp-remote proxy
- Supports both local development and production deployment
- Example math tool included for demonstration
Use cases of Remote MCP Server on Cloudflare
- Prototype and test a remote MCP server locally before deploying
- Connect Claude Desktop to a custom MCP server with OAuth security
- Deploy a scalable serverless MCP backend on Cloudflare’s edge network
- Demonstrate MCP tool calling with a simple arithmetic tool
FAQ from Remote MCP Server on Cloudflare
What is the difference between local development and production deployment?
Local development uses http://localhost:8787/sse and a mock login. Production deploys to a workers.dev URL with real OAuth authentication (requires an OAUTH_KV namespace).
What dependencies or runtime are required?
Node.js and pnpm (not npm) are required. For local development, use pnpm install and npx commands. The server itself runs on Cloudflare Workers.
How does authentication work?
The server includes an OAuth login page. Locally, a mock user/password screen appears. In production, Cloudflare Workers handle the OAuth flow with a KV store (OAUTH_KV) for session data.
Which transport is used?
The server uses Server‑Sent Events (SSE) as the transport protocol. Clients connect to the /sse endpoint.
Can I clear cached authentication data?
Yes, if OAuth issues arise, you can delete local auth files by running rm -rf ~/.mcp-auth and restarting Claude Desktop.
