Codex

OpenAI’s coding agent — the CLI, the IDE extension and the ChatGPT desktop app all share one config. Sign in with your ChatGPT account; Codex is included across ChatGPT plans.

Setup

Add to ~/.codex/config.toml:

[mcp_servers.artisan]
url = "http://127.0.0.1:9280/mcp"

Check it’s connected

Run codex mcp list (or type /mcp inside a session) — artisan appears with its tools.

Try it

With Rhino open, ask Codex:

“Create a round 1 ct diamond.”

The stone appears in your Rhino viewport. Not working? See Troubleshooting.
