+ Can use macOS Passwords
+ Easy access to ChatGPT
− No vertical tabs
− GPT-5 Instant being the default model is a big miss — at least give Auto for Pro users
Otherwise it’s basically “Dia but ChatGPT,” which already makes it better.
Things I want to see next:
– Pulse integration (bookmarks, history, maybe read-later)
– Full takeover from the ChatGPT Mac app (triggerable via ⌥ + space)
– Vertical tabs (yes please)
- A keyboard shortcut for Ask ChatGPT
– Codex (?)
1. How is your agent using MCP today?
2. Where did MCPX make your agent workflow easier?
3. Where did MCPX get in the way in real agent loops?
4. What MCP workflow do you want to do that MCPX still doesn’t support?
5. What output/error behavior made automation brittle?
Concrete examples or snippets are especially helpful.
