Install graphy in Codex

What you need first

• Codex, installed.
• uv, which gives the uvx command the server starts with.
• Your own value for YOUR__ABS_PATH_TO_REPO.

Steps

1. 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 graphyos -- uvx graphyos==0.2.3 mcp --repo YOUR__ABS_PATH_TO_REPO

2. Replace YOUR__ABS_PATH_TO_REPO with your own value.
3. Start Codex again and type /mcp: the server is listed.

Check it worked

Ask Codex: List the tools of graphyos.

If it does not start

spawn uvx ENOENT

uv is not on the PATH that Codex sees. Install it, or write the full path of uvx in the config.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.
