windbg_close
End session with q — closes the user-mode target (a kernel target stays locked)
How to use it
Project documentation lists windbg_close for the Windbg MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
