WHAT IT DOES

What scan_container_image does on Project Guardian MCP

AI agents invoke scan_container_image to trigger actions in Project Guardian 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 scan_container_image is rated High

This tool executes an external security scanning tool (Trivy) against a container image. It triggers an external operation whose effects depend on the image argument provided.

RECOMMENDED RULE

The rule that runs scan_container_image safely

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

scan_container_image Rate-limited

scan_container_image 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Project Guardian MCP, apply this rule, and every scan_container_image call is checked against it from then on.
