Connect Simplicate
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.
