What's Wrong?
Claude 1.24012.9 (03c61d) 2026-07-24T04:59:17.000Z Windows 11.
MCP Warnings will block the browser and Claude doesnt know that and keeps trying to screenshot it and gets nothing, I have to close the yellow MCP boxes my self, ugh the horror!
What Should Happen?
Claude code desktop should at least know the browser is blocked by the yellow MCP server warning boxes and not keep trying to render there and get nothing. Or not have it blocked by MCP warnings for browser operations.
Error Messages/Logs
i explained the bug to Claude:
again. its a bug in claude code where if there is an MCP warning, the yellow box blocks the browser. you should tell boris to fix that.
Here was Claudes respone:
thanks for the yellow-box tip — that explained my two "failed" probe runs perfectly: with the pane blocked, tick()'s fps cap skips the render, so single-tick probes read stale frames.Steps to Reproduce
It seems like I am running Claude Code Desktop already, and something restarts and the warning messages come up again (they come up on start), then an ongoing session cant read the browser anymore like the message in errors above.
