Install DataFinder MCP in Codex

What you need first

• Codex, installed.
• Node.js, which gives the npx command the server starts with.
• Your own values for YOUR_DATAFINDER_AK,YOUR_DATAFINDER_SK,YOUR_DATAFINDER_PROJECT_ID,YOUR_DATAFINDER_APP_ID,YOUR_DATAFINDER_SUBJECT_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 datafinder-mcp --env DATAFINDER_AK=YOUR_DATAFINDER_AK --env DATAFINDER_SK=YOUR_DATAFINDER_SK --env DATAFINDER_PROJECT_ID=YOUR_DATAFINDER_PROJECT_ID --env DATAFINDER_APP_ID=YOUR_DATAFINDER_APP_ID --env DATAFINDER_SUBJECT_ID=YOUR_DATAFINDER_SUBJECT_ID -- npx -y @cyuanxv/[email protected]

2. Replace YOUR_DATAFINDER_AK,YOUR_DATAFINDER_SK,YOUR_DATAFINDER_PROJECT_ID,YOUR_DATAFINDER_APP_ID,YOUR_DATAFINDER_SUBJECT_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 datafinder-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.
