Install Korean Fire Safety Law & Statistics in Codex

What you need first

• Codex, installed.
• Node.js, which gives the npx command the server starts with.
• Your own values for YOUR_DATA_GO_KR_KEY,YOUR_LAW_OC.

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 korean-firefighter-law-mcp --env DATA_GO_KR_KEY=YOUR_DATA_GO_KR_KEY --env LAW_OC=YOUR_LAW_OC -- npx -y [email protected]

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

Check it worked

Ask Codex: List the tools of korean-firefighter-law-mcp.

If it does not start

spawn npx ENOENT

Node.js is not on the PATH that Codex sees. Install it, or write the full path of npx in the config.

The server starts, but its tools fail

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