RECOMMENDED RULE

The rule that runs libi.render_overlay_frames safely

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

libi.render_overlay_frames Rate-limited

libi.render_overlay_frames 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.
