Install Archery MCP in Codex

What you need first

• Codex, installed.
• uv, which gives the uvx command the server starts with.
• Your own values for YOUR_ARCHERY_BASE_URL,YOUR_ARCHERY_USERNAME,YOUR_ARCHERY_PASSWORD,YOUR_ARCHERY_INSTANCE_NAME,YOUR_ARCHERY_DB_NAME.

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 archery-mcp --env ARCHERY_BASE_URL=YOUR_ARCHERY_BASE_URL --env ARCHERY_USERNAME=YOUR_ARCHERY_USERNAME --env ARCHERY_PASSWORD=YOUR_ARCHERY_PASSWORD --env ARCHERY_INSTANCE_NAME=YOUR_ARCHERY_INSTANCE_NAME --env ARCHERY_DB_NAME=YOUR_ARCHERY_DB_NAME -- uvx archery-mcp==0.1.1

2. Replace YOUR_ARCHERY_BASE_URL,YOUR_ARCHERY_USERNAME,YOUR_ARCHERY_PASSWORD,YOUR_ARCHERY_INSTANCE_NAME,YOUR_ARCHERY_DB_NAME with your own values.
3. Start Codex again and type /mcp: the server is listed.

Check it worked

Ask Codex: List the tools of archery-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.
