Codex CLI and IDE extension

1. Run:

   TerminalCopy

   codex mcp add trenz --url https://mcp.trenz.ai/mcp/oauth

2. Codex opens a trenz.ai page in your browser. Sign in if asked, then click Allow. If the browser does not open, run codex mcp login trenz.

The app, the CLI and the IDE extension share the same configuration, so adding Trenz in one makes it available in the others.

Next, install the Trenz skill for the Codex CLI.
