WHAT IT DOES

What monitor_resolution_change does on Mcp Windows

AI agents invoke monitor_resolution_change to trigger actions in Mcp Windows. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why monitor_resolution_change is rated High

This tool modifies system display settings (resolution and refresh rate), which is an external system operation with immediate effect. It's not purely a data write to a database but rather executes a system-level configuration change. While potentially reversible, misuse could cause display issues (e.g., unsupported resolution leaving screen unusable).

RECOMMENDED RULE

The rule that runs monitor_resolution_change safely

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

monitor_resolution_change Rate-limited

monitor_resolution_change stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
