When the tool is called and the OpenAI MCP agent returns an error message: ‘ToolError: None: MCP write action is temporarily disabled.’

This was literally working minutes ago, now I can’t seem to make it work again no matter what I do. OpenAI team should look at it, especially as it says it is fully functional. This is an extremely frustating development experience.

If anyone is still experiencing this issue, it appears to be related to caching after building the new UI. In case anyone is still facing, trying the following did the trick for me:

  1. Restart the MCP server after providing the new UI files;
  2. Refresh tool metadata (In Settings → Connectors, click into your connector and choose Refresh);
  3. Clear the browser cache (Ctrl + F5);
  4. If none of the above work, create a new chat and call the tool again.

Sorry for the rage last comment, the caching handling is definitely something that can get better, but it is far from an outage :slightly_smiling_face:
