Sounds like OpenAI is limited to 128 tools.

Looks like you have multiple MCP servers installed, some of which provide many tools (e.g. GitHub MCP provides 50-something if I remember correctly).

I suggest you clone the Write profile and uncheck some of the tools you don't need for this session. In general the models will perform better if you don't include a bunch of unnecessary tools.
