I’m working with Cursor, or trying to work with Cursor in the macOS app, and I connected it, I’ve installed Codex Extension, but when I’m working with it in ChatGPT, it says inactive, what does it mean inactive, what’s inactive, I already connected it, it can’t see what I’m doing, I have a lot of research chat within a specific thread, if you will, the macOS part within ChatGPT. Now I want to be able to use the knowledge it’s got there to work within the IDE, hence this connection, but it says inactive. What’s inactive? How do I get it to work so it’s lit up green?

OK i got this working, so it can see files and edit them, does anyone know if it can call Supabase MCP server that’s the missing link imo? @deanrie anyone? Reason I am doing this is because i have a lot of context stuck in chatGPT and want to connect the two systems
Hey, thanks for the question. Glad the connection is working.
To your question: no, the ChatGPT macOS app (via the Codex extension) can’t call Cursor’s MCP servers. Here’s why:
- Codex is an OpenAI extension that lets ChatGPT view and edit files in Cursor
- MCP servers are a Cursor‑native feature that only work inside Cursor’s Agent/Chat
- These are separate systems with no integration path
Alternative ways to transfer context:
- Copy relevant conversation context from ChatGPT and paste it into a Cursor chat
- Use Cursor’s Agent directly with your configured Supabase MCP server (it will have full context of your codebase)
- Save key insights from ChatGPT into a markdown file in your project that Cursor can reference
With Cursor Agent + MCP servers, you’ll likely get everything you need without ChatGPT in the loop.
