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.
