Overview

What is Remote MCP Server on Cloudflare?

Remote MCP Server on Cloudflare is a ready-to-deploy model context protocol server that runs on Cloudflare Workers and includes OAuth login integration. It is intended for developers who want to host an MCP server remotely and connect it to clients like Claude Desktop or the MCP Inspector.

How to use Remote MCP Server on Cloudflare?

Clone the repository, install dependencies with npm install, and run locally with npx nx dev remote-mcp-server. Connect via SSE URL (e.g., http://localhost:8787/sse). To deploy, create a KV namespace with npx wrangler kv namespace create OAUTH_KV, add its ID to wrangler.jsonc, and run npm run deploy. Then use the deployed workers.dev/sse endpoint with any MCP client.

Key features of Remote MCP Server on Cloudflare

  • Runs on Cloudflare Workers for serverless deployment
  • Includes OAuth login for authentication
  • Supports SSE (Server-Sent Events) transport
  • Works with MCP Inspector and Claude Desktop
  • Local development with hot reload via Nx
  • Uses Cloudflare KV for OAuth state storage

Use cases of Remote MCP Server on Cloudflare

  • Host a remote MCP server for Claude Desktop to call tools over HTTP
  • Develop and test MCP tools locally with the MCP Inspector
  • Deploy a production MCP server with built-in OAuth authentication
  • Share MCP tools with remote clients without exposing local infrastructure

FAQ from Remote MCP Server on Cloudflare

How do I connect Claude Desktop to the remote server?

Add an entry to your Claude Desktop configuration file (claude_desktop_config.json) using npx mcp-remote pointing to your server’s SSE URL (e.g., https://worker-name.account-name.workers.dev/sse).

What do I need to deploy to Cloudflare?

You need a Cloudflare account, the Wrangler CLI (npx wrangler), and a KV namespace created via npx wrangler kv namespace create OAUTH_KV. The KV namespace ID must be added to your wrangler.jsonc file.

Where does OAuth session data live?

Session data is stored in Cloudflare KV under the namespace OAUTH_KV. Clearing local auth files (rm -rf ~/.mcp-auth) can help with debugging login issues.

Can I test the server without deploying?

Yes, run npx nx dev remote-mcp-server locally and connect via the MCP Inspector using http://localhost:8787/sse as the SSE URL.

How do I debug connection issues?

Restart Claude or test the connection directly with npx mcp-remote http://localhost:8787/sse. In rare cases, clear files in ~/.mcp-auth.
