It seems like MCP servers do not actually work on Warp for Windows. I am on Windows 11. Is this a known issue and is there any workaround?

Hi @dawn ingot. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Yes, there are multiple reports indicating that MCP servers often fail to work properly on Warp for Windows. Users have consistently encountered the "Failed to start client" error when attempting to start MCP servers, even when those same servers work in other environments and IDEs. This issue has been reported for both the stable and preview versions of Warp on Windows 10 and 11. For example, one user described always getting "client failed to start" when trying to use an MCP server on Warp Preview for Windows 10, and another reported the same issue on Windows 11 with the Task Master AI MCP server, despite it working in other IDEs and terminals. The error is not isolated to a specific MCP server or configuration, and there is no official workaround documented in the knowledge sources provided. The Warp team has acknowledged these issues and sometimes directs users to provide logs or use the Warp Community Slack for further troubleshooting, but no definitive fix or workaround is currently documented for Windows usersTask Master AI mcp server failed to start client mcpserver not working.
If you are experiencing this issue, you may want to:
- Ensure your configuration matches the documented examples.
- Try running the same MCP server on a different OS (macOS or Linux) if possible, as users report better success there.
- Share your logs with the Warp team via their Slack community for more targeted troubleshooting.
