Overview

What is Remote MCP Server on Cloudflare?

A starter project for running a remote MCP (Model Context Protocol) server on Cloudflare Workers, complete with OAuth login. It is intended for developers who want to deploy an MCP server that can be accessed by remote MCP clients like Claude Desktop.

How to use Remote MCP Server on Cloudflare?

Clone the repository, install dependencies (npm install), and run locally with npx nx dev remote-mcp-server. Optionally, deploy to Cloudflare using npm run deploy after creating a KV namespace (npx wrangler kv namespace create OAUTH_KV). Connect clients (MCP Inspector or Claude Desktop) using SSE at a /sse endpoint.

FAQ from Remote MCP Server on Cloudflare

How do I connect Claude Desktop to the remote server?

Update your Claude Desktop configuration (claude_desktop_config.json) to use npx mcp-remote with the Workers URL (e.g., https://worker-name.account-name.workers.dev/sse) as an argument.

What dependencies or runtime are required?

Node.js, npm, and a Cloudflare account for deployment. Local development uses npx nx and wrangler.

Where does authentication data live?

OAuth session data is stored in a Cloudflare KV namespace (OAUTH_KV). Locally, authentication state may be cached in ~/.mcp-auth.

Can I debug connection issues?

Yes. Try restarting Claude, connecting via npx mcp-remote http://localhost:8787/sse directly, or clearing ~/.mcp-auth files if needed.

How do I deploy to production?

Run npx wrangler kv namespace create OAUTH_KV, add the KV namespace ID to wrangler.jsonc, then run npm run deploy.
