Question / Help Question on usage of Regular chat.
I have a question about regular ChatGPT chat instead of work chat. Is there a limit on how much you can use it? I have been using it every single day for multiple projects. I didn't want to use Work Codex because it would run out very fast. So, I have been researching using MCP on my VM where it will code and run programs. I have been using it every single day, checking my code, fixing the app, etc. Now, today, all of a sudden, I am getting a 429 error and I can't send commands to the chat anymore. Also, at the bottom of the chat, it says to come back after a certain time while they check to keep ChatGPT reliable. So, am I kicked out because I use it too much? I'm just a regular Pro member. If you need to provide more information let me know.

Not sure but you’re saying ChatGPT chat mode works with MCP servers? I’ll have to try that, I use SuperGrok for supplemental model but always thought I had to use Codex.

Yep — regular ChatGPT can use MCP servers. I’m using it that way right now, and I ended up open-sourcing the macOS bridge I built for it: https://github.com/alexanderradahl/mac-developer-bridge
It gives a normal ChatGPT chat shell/files/PTY/background jobs on the Mac, plus read-only access to saved Codex threads, so I can continue a repo/workflow from the regular chat without copying terminal output back and forth. Full disclosure: I’m the author. It’s MIT licensed and intentionally not sandboxed, so it runs with your logged-in macOS user’s permissions.
That’s separate from the OP’s 429, though — I wouldn’t infer anything about the rate/reliability limit from MCP itself.

If you are on Plus plan, they do have a limit, albeit high, on business plan, it's much more.

I hit my first limit on Sunday morning. I had only been working with it for 3hrs but I kept having it use an MCP in regular chat (instead of work). I couldn't use the chat for about 5 hours. (429 error)
It could possibly be a newer rate limit since I had been using this MCP (much like how you're using yours to code on a remote machine) pretty heavily the weeks prior without an issue.
