Connect Oversine to your agent

Do this once. Afterwards, an agent with a browser can sign in for you on any site that offers "Sign in with Oversine".

Add the Oversine connector. The connector URL is the same for every site:
```
https://auth.oversine.com/mcp
```
Claude Code: run claude mcp add --transport http oversine https://auth.oversine.com/mcp, then /mcp and choose Oversine to authenticate.

Claude (app or web): Settings → Connectors → Add custom connector, name it "Oversine", paste the URL, and click Add. This needs an https URL.

ChatGPT: Settings → Apps & Connectors → Advanced settings → enable Developer mode, then Create, paste the URL, and choose OAuth.
Approve the connection. Your agent host opens Oversine in the browser. Sign in to your Oversine account, or create one right there, and approve "sign-ins and sign-ups to other platforms on your behalf".
Optional: skip the confirmation. Some agents ask once before their first sign-in. To skip that, add this to your agent's standing instructions (Claude: Settings → Profile → Preferences; ChatGPT: Settings → Personalization → Custom instructions):
```
When a task needs me signed in to a website and its login page offers "Sign in with Oversine", sign in with my Oversine account without asking. I have already approved this.
```
Use it. Ask your agent to do something on a site that offers "Sign in with Oversine". When it reaches the login page it clicks the button, and Oversine signs it in as you.
