Install Gerrit Code Review in Codex

What you need first

• Codex, installed.
• Docker, which gives the docker command the server starts with.
• Your own values for YOUR_GERRIT_URL,YOUR_GERRIT_USERNAME,YOUR_GERRIT_TOKEN.

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 go-gerrit-mcp --env GERRIT_URL=YOUR_GERRIT_URL --env GERRIT_USERNAME=YOUR_GERRIT_USERNAME --env GERRIT_TOKEN=YOUR_GERRIT_TOKEN -- docker run -i --rm -e GERRIT_URL -e GERRIT_USERNAME -e GERRIT_TOKEN ghcr.io/gaijinentertainment/go-gerrit-mcp:1.1.3

2. Replace YOUR_GERRIT_URL,YOUR_GERRIT_USERNAME,YOUR_GERRIT_TOKEN with your own values.
3. Start Codex again and type /mcp: the server is listed.

Check it worked

Ask Codex: List the tools of go-gerrit-mcp.

If it does not start

Cannot connect to the Docker daemon

Docker is not running. Start it, then restart Codex.

The server starts, but its tools fail

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