概要

What is Remote MCP Server on Cloudflare?

A starter project to deploy a remote MCP (Model Context Protocol) server on Cloudflare Workers with OAuth login, enabling tools to be called from remote MCP clients like Claude Desktop.

How to use Remote MCP Server on Cloudflare?

Clone the repository, install dependencies with npm install, then run locally with npx nx dev remote-mcp-server. Connect using the MCP Inspector with SSE transport (e.g., http://localhost:8787/sse). For Claude Desktop, configure mcpServers with npx mcp-remote pointing to the SSE URL. Deploy to production with npm run deploy after creating an OAuth KV namespace.

よくある質問

What dependencies or runtime are required?

Node.js and npm are required for local development, running the MCP Inspector, and the `mcp-remote` proxy. The deployed server runs on Cloudflare Workers with a KV namespace for OAuth state.

How do I connect to the server remotely?

Use an MCP client (e.g., MCP Inspector or Claude Desktop) with the SSE transport and the Worker’s `workers.dev` URL (e.g., `https://worker-name.account-name.workers.dev/sse`). The client must support OAuth redirect for login.

Where does OAuth data live?

OAuth session data is stored in a Cloudflare KV namespace (`OAUTH_KV`) created during deployment setup and referenced in `wrangler.jsonc`.

How can I debug connection issues?

Restart the MCP client or try connecting directly via command line: `npx mcp-remote http://localhost:8787/sse`. In rare cases, clear the local auth cache with `rm -rf ~/.mcp-auth`.

What transport method does the server use?

The server uses Server-Sent Events (SSE) as the MCP transport, accessible at the `/sse` endpoint of both the local and deployed Worker URLs.
