Describe the Bug

Hello Cursor:
Today I was working on a front end page while using cursor. When calling the official Figma MCP, there is always an issue about the model provider connection failing to work.

Steps to Reproduce

Not quite sure if it’s mcp related or not, anyway, now I get this error whenever I ask a question, and it’s been going on for about 4 hours now.

Expected Behavior

Expected a normal reply, but there was none.

I’ve found that the error occurs when the MCP fails in a previous chat turn, or when the cursor’s memories are invoked beforehand. The issue might be related to how the context is sent. The cursor has updated something.
