3## Notes for agents
4
5**Not a pnpm workspace package, on purpose.** The MCP SDK is this script's only dependency; adding it to the workspace would put it in the site's pnpm closure and its nix hash. `npm install` here, pinned in `package.json`.
6
7**Never point either script at the user's dev server (4322/4323), the preview (4324) or the public site.** It creates accounts and publishes a song where it runs, and plays sound in its own headless tab only.
8
9**The loopback callback must be a real server.** Playwright's `page.route` does not intercept the redirect the consent form answers with, so the client listens on `127.0.0.1:<port>` as Claude Code does (2026-09-26).
