FAQ from Remote MCP Server on Cloudflare

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.
