Frequently asked questions

1

How do I develop the server locally?

Clone the repository, run `npm install`, then execute `npx nx dev remote-mcp-server` and open `http://localhost:8787/` in your browser.

2

How can I test the server with MCP Inspector?

Start the inspector with `npx @modelcontextprotocol/inspector`, set Transport Type to `SSE` and URL to `http://localhost:8787/sse`, then click Connect. A mock login screen appears; enter any email and password.

3

How do I connect Claude Desktop to my local server?

Edit Claude Desktop’s config file (`Settings > Developer > Edit Config`) and add an MCP server with command `npx` and args `["mcp-remote", "http://localhost:8787/sse"]`. Restart Claude to see available tools.

4

How do I deploy the server to Cloudflare?

Create a KV namespace with `npx wrangler kv namespace create OAUTH_KV`, add the namespace ID to `wrangler.jsonc`, then run `npm run deploy`. Your server will be available at a `workers.dev` URL.

5

What should I do if something goes wrong?

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