+description: "NVIDIA App control through its local MCP server: overlay capture and state, driver status
+  and release notes, game optimization, and app launch. Requires NVIDIA App 11.0 or newer on Windows;
+  the install is refused when the app is absent, and the tools appear while the app's service is running.
+  The plugin reads the endpoint and token NVIDIA App publishes in its own McpServer server.json on every
+  connection, so a changed port or token needs no reconfiguration. Disclosure: the tools read and change
+  NVIDIA App settings on this machine; nothing leaves loopback."
