grok-plugin lets Claude delegate to Grok via your SuperGrok login — on an undocumented API
eyishazyer · x · 2026-08-20
Discussion of a project called grok-plugin: an MCP server that logs in through xAI's OAuth device flow, letting Claude Code hand work straight to Grok without ever touching an xAI API key — it runs on the SuperGrok or X Premium subscription you already pay for. A login link appears in-chat the first time Claude tries to delegate something.
The poster finds the concept clever but flags the real risk: it relies on an undocumented API, so xAI could change or block it at any time, with no stability guarantees.
