Hey, thanks for the report. I see the screenshot with the error, this is a known issue.
During MCP tool auto-calls, the model sometimes doesn’t pass required args, and the call gets sent with an empty {}. This shows up more often in Plan Mode because it has a different set of available tools. A few users have hit the same thing across different MCP servers (GitHub, Linear, and others):
- MCP tool called without required "key" arg during Agent auto-call, manual call works
- Regression: agent can no longer create PRs via GitHub MCP (`create_pull_request` without arguments)
The team is aware. Until it’s fixed, the workaround is to use Agent Mode for MCP tool calls.
Let me know if you have any questions.
