Frequently asked questions

1

How do I test the server locally?

Run `npx nx dev remote-mcp-server` and open `http://localhost:8787/`. Use the MCP Inspector with SSE and URL `http://localhost:8787/sse`.

2

How do I connect Claude Desktop to the server?

Edit Claude Desktop’s config file and add an entry using `npx mcp-remote` with the server’s SSE URL (local `http://localhost:8787/sse` or remote `https://worker-name.account-name.workers.dev/sse`).

3

What dependencies are required?

Node.js and npm are needed for local development. Deployment requires a Cloudflare account and `wrangler` CLI.

4

Where is authentication data stored?

OAuth data is stored in a Cloudflare KV namespace (`OAUTH_KV`) created via `npx wrangler kv namespace create`.

5

How can I debug connection issues?

Restart Claude, or test the server directly with `npx mcp-remote http://localhost:8787/sse`. In rare cases, clear `~/.mcp-auth` with `rm -rf ~/.mcp-auth`.
