Install Unraid MCP in Codex

What you need first

• Codex, installed.
• uv, which gives the uvx command the server starts with.
• Your own values for YOUR_UNRAID_API_URL,YOUR_UNRAID_API_KEY.

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 unraid-mcp --env UNRAID_API_URL=YOUR_UNRAID_API_URL --env UNRAID_API_KEY=YOUR_UNRAID_API_KEY -- uvx unraid-mcp==2.10.3

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

Check it worked

Ask Codex: List the tools of unraid-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.
