FAQ from Remote MCP Server on Cloudflare

What does Remote MCP Server on Cloudflare do?

It provides a template and instructions to run an MCP server on Cloudflare Workers with OAuth login, allowing remote clients to list and call tools.

What are the runtime dependencies?

You need Node.js and npm to install dependencies, and Nx is used to run the server locally. Cloudflare Workers is the deployment platform, and an OAuth KV namespace is required for OAuth state storage.

Where does OAuth data live?

OAuth data is stored in a Cloudflare KV namespace named OAUTH_KV, which you create during deployment.

What transport protocol does the server use?

The server uses Server-Sent Events (SSE) as its transport protocol. Clients connect using an SSE URL, e.g., http://localhost:8787/sse or a workers.dev URL.

How do I debug connection issues?

Restart Claude, or test the connection directly on the command line with npx mcp-remote <URL>. Clearing ~/.mcp-auth files can help in rare cases.
