Frequently asked questions

1

How do I connect Claude Desktop?

Edit the Claude Desktop config file to add an `mcpServers` entry with command `npx` and args `["mcp-remote", "http://localhost:8787/sse"]` for local, or the Workers URL for remote access.

2

What transport protocol does it use?

It uses Server-Sent Events (SSE) over HTTP as the transport protocol.

3

How do I deploy to Cloudflare?

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

4

How do I debug connection issues?

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

5

Where is the OAuth state stored?

OAuth state is stored in a Cloudflare KV namespace configured via `wrangler.jsonc`.
