# Troubleshooting

> Fix connection and authentication issues with the Kernel MCP server

* **Cursor clean reset:** ⌘/Ctrl Shift P → run `Cursor: Clear All MCP Tokens` (resets all MCP servers and auth; re-enable Kernel and re-authenticate).
* **Clear saved auth and retry:** `rm -rf ~/.mcp-auth`
* **Node.js version:** Ensure a recent Node.js version when using `npx mcp-remote`.
* **Strict networks:** If behind strict networks, try stdio via `mcp-remote`, or explicitly set the transport your client supports.
