Install TOP GUN GEO-Lens 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 top-gun-geo-lens --url https://top-gun-mcp-server.vercel.app/api/mcp- Start Codex again and type
/mcp: the server is listed.
Check it worked
Ask Codex: List the tools of top-gun-geo-lens.
If it does not start
- 401 Unauthorized
- The endpoint wants a sign-in or a key. Sign in when Codex asks.
