Install pitwall-mcp in Codex

What you need first

• Codex, installed.
• uv, which gives the uvx command the server starts with.
• Your own values for YOUR_PITWALL_CLIENT_ID,YOUR_PITWALL_VIN,YOUR_PITWALL_CONTAINER_ID.

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 pitwall-mcp --env PITWALL_CLIENT_ID=YOUR_PITWALL_CLIENT_ID --env PITWALL_VIN=YOUR_PITWALL_VIN --env PITWALL_CONTAINER_ID=YOUR_PITWALL_CONTAINER_ID -- uvx pitwall-mcp==0.1.1

2. Replace YOUR_PITWALL_CLIENT_ID,YOUR_PITWALL_VIN,YOUR_PITWALL_CONTAINER_ID with your own values.
3. Start Codex again and type /mcp: the server is listed.

Check it worked

Ask Codex: List the tools of pitwall-mcp.

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.
