This issue might be a duplicate of existing issues. Please check:

• Task Tool Timeouts & Early Termination in Multi-Agent Conductor Pattern #6792: Task Tool Timeouts & Early Termination in Multi-Agent Conductor Pattern - describes tasks/execution stopping and returning session IDs prematurely
• Strangely enough, it always gets stuck or encounters an exception during task execution. #4319: Strangely enough, it always gets stuck or encounters an exception during task execution - describes execution halting midway without clear errors
• Hanging During Agent Tasks #4073: Hanging During Agent Tasks - describes tool calls stopping and no further progress being made
• MCP server failed to start (unstable MCP servers) #829: MCP server failed to start (unstable MCP servers) - mentions MCP server connection issues that can cause hanging

These issues all describe similar symptoms of execution prematurely stopping or halting during task completion. Your issue with playwright/playwriter MCP tools stopping before task completion appears related to this pattern.

Feel free to ignore if none of these address your specific case.

Does this only happen when using that mcp server?

Yeah mainly the playwriter mcp, I swear I had issues with the official playwright mcp earlier today too. Both seem to be fine in claude code

I am having the Same Issue , I think not only playwright, even chrome dev tool, and i think more MCPs can cause this cut in the executing, and none browser MCPs can lead to the same issue , I have been trying to solve it all day , nothing worked

Are You Using any type of proxy for your LLMs? I have been trying without the proxy seems I have different results
