Connect Uno to ChatGPT
No API documentation required. Paste one MCP endpoint, sign in in the browser, and give your agent a real task.

Enable Developer mode
In ChatGPT on the web, open Settings → Apps → Advanced settings and enable Developer mode. A workspace admin may need to allow it.
Create the Uno app
Go to Settings (or Workspace settings) → Apps → Create. Name it Uno, paste the MCP endpoint below, choose OAuth, then select Scan tools.
Sign in and authorize
Uno opens in the browser for sign-in. Return to ChatGPT, review the scanned tools, and create the app. Uno will request a separate app authorization only when a task needs it.
Verify in a real chat
Start a new chat, enable the Uno app, and paste the safe test task below. Begin with a small reversible write; Uno never auto-retries a non-idempotent operation.
First real task
Use Uno to find a read-only weather tool, check the current weather in Beijing, and tell me which tool you used.
