WHAT IT DOES

What ai.screenshot does on Mcp

AI agents invoke ai.screenshot to trigger actions in Mcp. 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 ai.screenshot is rated High

This tool launches a headless browser to navigate to an arbitrary URL and capture a screenshot — it executes external browser operations whose effects depend on the provided URL argument. It is not a simple read/fetch; it involves running browser automation.

RECOMMENDED RULE

The rule that runs ai.screenshot safely

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

ai.screenshot Rate-limited

ai.screenshot 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.
