The only thing missing now is support on mobile, then ChatGPT could be an actual assistant.

And here I am still waiting for some kind of hooks support for ChatGPT/Codex.

I wonder if this is going to be used by JetBrains AI in any capacity.

I'm confused and I'm a developer

Same. What exactly is "developer" about:

> Schedule a 30‑minute meeting tomorrow at 3pm PT with

> alice@example.com and bob@example.com using "Calendar.create_event".

> Do not use any other scheduling tools.

Only footgun operators may apply is what they mean.

That's because you need to Go to Settings → Connectors → Advanced → Developer mode.

That is pretty common.

Am I the only one who doesn’t know what MCP is/means? Of course I’m about to go look it up, but if someone can provide a brief description of what it is then I’d be very appreciative. Thanks!
