Install D365fo Connector in Codex

What you need first

• Codex, installed.
• Node.js, which gives the npx command the server starts with.
• Your own values for YOUR_D365_TENANT_ID,YOUR_D365_CLIENT_ID,YOUR_D365_CLIENT_SECRET,YOUR_D365_ENVIRONMENT_URL.

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 d365fo-connector --env D365_TENANT_ID=YOUR_D365_TENANT_ID --env D365_CLIENT_ID=YOUR_D365_CLIENT_ID --env D365_CLIENT_SECRET=YOUR_D365_CLIENT_SECRET --env D365_ENVIRONMENT_URL=YOUR_D365_ENVIRONMENT_URL -- npx -y @zhound/[email protected]

2. Replace YOUR_D365_TENANT_ID,YOUR_D365_CLIENT_ID,YOUR_D365_CLIENT_SECRET,YOUR_D365_ENVIRONMENT_URL with your own values.
3. Start Codex again and type /mcp: the server is listed.

Check it worked

Ask Codex: List the tools of d365fo-connector.

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.
