To connect NanoCorp to Codex, add NanoCorp’s MCP server, https://mcp.nanocorp.so, with two commands, then allow the connection in your browser.

​
Add NanoCorp

In your terminal:

​
Sign in

Sign in to NanoCorp in your browser, or create your account there. The confirmation page says your access goes to this computer. Click Allow.

​
Check the connection

Run codex mcp list in your terminal, or /mcp in Codex. Then ask Codex, for example, “List my NanoCorp businesses”. The Codex command line, the Codex IDE extension and the ChatGPT desktop app share this setup, so you add NanoCorp once. See OpenAI’s Codex documentation. To have Codex build a business’s code through the NanoCorp command line instead, see the CLI.
