Install Google Sign In Langchain Agent in Codex
What you need first
- Codex, installed.
- Nothing else: the server runs on its publisher's machines and Codex connects to it.
Steps
- Run this in a terminal. It writes the server into
~/.codex/config.toml, which the Codex CLI, its IDE extension and the ChatGPT desktop app share.
codex mcp add google-sign-in-langchain-agent --url https://google-auth-oauthlib-langchain-la-d46b90.getvda.ai/mcp- Start Codex again and type
/mcp: the server is listed.
Check it worked
Ask Codex: List the tools of google-sign-in-langchain-agent.
If it does not start
- 401 Unauthorized
- The endpoint wants a sign-in or a key. Sign in when Codex asks.
