WHAT IT DOES

What show_screenshot_preview does on CLIO Adios

AI agents invoke show_screenshot_preview to trigger actions in CLIO Adios. 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 show_screenshot_preview is rated High

Taking a screenshot is an execution action that captures current screen state and writes temporary files. It is not a simple read of existing data but an active operation that interacts with the display system and filesystem. The blast radius is medium as it could capture sensitive on-screen information.

From the tool's definition 'Capture a screenshot' indicates an active operation that triggers an external action (screen capture) using temporary files

RECOMMENDED RULE

The rule that runs show_screenshot_preview safely

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

show_screenshot_preview Rate-limited

show_screenshot_preview 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.
