Install Victoriatraces in Codex

What you need first

• Codex, installed.
• Docker, which gives the docker command the server starts with.
• Your own values for YOUR_VT_INSTANCE_ENTRYPOINT,YOUR_VT_INSTANCE_BEARER_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 mcp-victoriatraces --env VT_INSTANCE_ENTRYPOINT=YOUR_VT_INSTANCE_ENTRYPOINT --env VT_INSTANCE_BEARER_TOKEN=YOUR_VT_INSTANCE_BEARER_TOKEN -- docker run -i --rm -e VT_INSTANCE_ENTRYPOINT -e VT_INSTANCE_BEARER_TOKEN ghcr.io/victoriametrics-community/mcp-victoriatraces:1.5.0

2. Replace YOUR_VT_INSTANCE_ENTRYPOINT,YOUR_VT_INSTANCE_BEARER_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 mcp-victoriatraces.

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.
