FAQ from Remote MCP Server on Cloudflare

What dependencies are required to run this server?

You need Node.js, npm, and the Cloudflare Wrangler CLI (npx wrangler). The project uses nx for monorepo orchestration.

How do I deploy the server to Cloudflare?

Run npx wrangler kv namespace create OAUTH_KV, add the returned ID to wrangler.jsonc, then run npm run deploy.

How can I test the MCP server locally?

Start the development server with npx nx dev remote-mcp-server, then connect using the MCP Inspector (npx @modelcontextprotocol/inspector) with URL http://localhost:8787/sse and SSE transport.

How do I connect Claude Desktop to the remote server?

Update Claude’s config file to use mcp-remote with the Workers URL (e.g., https://worker-name.account-name.workers.dev/sse). Restart Claude; a browser will open for OAuth login.

How can I clear authentication issues?

If login problems persist, clear the cached auth files with rm -rf ~/.mcp-auth.
