RECOMMENDED RULE

The rule that runs vision.get_artifact safely

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

vision.get_artifact Allowed

vision.get_artifact is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
