Connect Codex to Certifier
Set up in minutes
Choose where it runs
On your computer through your own Codex, or hosted in the cloud. The rest of setup adapts to your choice:
Pick what it can do in Certifier
A preset of real Certifier operations. Each one becomes a tool the agent can call, and it can't touch anything outside the list.
Connect Certifier
One sign-in. The agent acts through your account, scoped to the operations you picked.
Add your personal MCP link
The last step mints a private MCP URL for this agent and walks you through exactly this, with your real link filled in. The page flips to Connected the moment your Codex first calls in. Codex connects when a session starts — run codex, or restart a running one (in the Codex app, Restart).
Run this in your terminal. The Codex app shares its config, so it gets the server too
<your-link> is your personal server URL — setup mints it for you.
