Hey, thanks for the report. The `tools[0].type:type cannot be empty` error points to a formatting issue on our side when we send tool definitions to the model provider. A few questions to narrow it down: - Does this happen in all projects, or only one specific project? - Do you have any MCP servers set up (Cursor Settings \> MCP)? - Does starting a brand new chat (not continuing an existing one) also trigger the error? - Does anything change after restarting Cursor? Also, could you try switching to a different built-in model (for example, GPT-5) to see if this is specific to Claude? Let me know your answers to the questions above, and that’ll help us figure out what’s causing it. ---

1.all projects 2.install laravel/boost,But even closing it doesn’t work, and uninstalling and reinstalling cursor doesn’t work either. 3.Even opening a new chat window doesn’t work. Not even restarting 4.This problem did not occur when using a custom model. ---

I have the same problem. Provider returned error: {“error”:{“code”:“1214”,“message”:“tools[0].type:type cannot be empty.”}} Request ID: d3a710d5-c664-42fc-95ea-7d1fa2839849 I have tried to change the model, change the prompt itself, restart Cursor and restart PC. I was trying to make a “plan”. I am working on windows. ---
