Overview
What is Remote MCP Server on Cloudflare?
This project provides a template to run a remote Model Context Protocol (MCP) server on Cloudflare Workers, complete with OAuth login. It is intended for developers who want to host MCP servers that can be accessed by AI clients like Claude Desktop over HTTP/SSE.
How to use Remote MCP Server on Cloudflare?
Clone the repository, install dependencies, and run locally with npx nx dev remote-mcp-server. For deployment, use npm run deploy after configuring a KV namespace. Connect clients like the MCP Inspector or Claude Desktop by pointing them to the server’s /sse endpoint. A local proxy (npx mcp-remote) is required for Claude Desktop.
Key features of Remote MCP Server on Cloudflare
- Runs on Cloudflare Workers with edge deployment
- Includes OAuth login for secure access
- Uses SSE (Server-Sent Events) transport
- Works with MCP Inspector for testing
- Works with Claude Desktop via a local proxy
Use cases of Remote MCP Server on Cloudflare
- Hosting a remote math tool MCP server for AI assistants
- Prototyping and testing MCP tools with the MCP Inspector
- Deploying a persistent, cloud-hosted MCP server accessible from any MCP client
FAQ from Remote MCP Server on Cloudflare
How do I connect the MCP Inspector to the server?
Set the Transport Type to SSE and enter the server URL (e.g., http://localhost:8787/sse) in the inspector, then click Connect. You will be prompted with a login screen.
How do I connect Claude Desktop to a locally running server?
Add a configuration entry in Claude’s settings using npx mcp-remote with the local URL (e.g., http://localhost:8787/sse). Claude will open a browser for OAuth login.
How do I deploy the server to Cloudflare?
Use npx wrangler kv namespace create OAUTH_KV, add the namespace ID to wrangler.jsonc, then run npm run deploy.
Can I connect Claude Desktop to the deployed remote server?
Yes. Update the Claude configuration to point to the deployed Workers URL (e.g., https://worker-name.account-name.workers.dev/sse) and restart Claude.
What do I do if something goes wrong?
Restart Claude, or test the connection directly via npx mcp-remote <URL>. If needed, clear the local auth cache by running rm -rf ~/.mcp-auth.
