Connect Codex CLI to CockroachDB

One line gives Codex CLI your CockroachDB account as tools: 7 endpoints, clusters, called with your own connection. No key in the prompt, a receipt for every call, revoke Codex CLI's access alone any time.

Get the line for Codex CLIConnect CockroachDB first

Three steps

  1. Create a free 0n3 account and connect CockroachDB. Paste a key or sign in; it lands in your vault, encrypted.
  2. Install 0n3 into Codex CLI. OpenAI's terminal agent reads 0n3 over Streamable HTTP with a token from your environment.
  3. Ask Codex CLI: whoami. Then: "List clusters in CockroachDB".
Put the token in your environment
export ON3_TOKEN="<your 0n token>"

Add it to your shell profile so Codex finds it next time.

The line above carries a placeholder; 0n3.app/install mints a real key named for Codex CLI and fills it in.
