WHAT IT DOES

What Notification does on Windows-MCP

AI agents use Notification to create or update resources in Windows-MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Windows-MCP environment.

RISK

Why Notification is rated Medium

This tool creates transient notification objects that do not persist or modify underlying data, configuration, or system state. While it is an output action (not purely observational like Read), it is reversible and non-destructive—the notification can be dismissed and leaves no lasting impact. It does not execute code, delete data, or move money.

From the tool's definition The tool 'Sends a Windows toast notification with a title and message.' creates a temporary UI element (notification) that is displayed to the user without modifying system data or configuration.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs Notification safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Windows-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For Notification, this is the rule to start with:

Notification Rate-limited

Notification stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
