Attacks that exploit this kind of access
The rule that runs get_node_constants safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_node_constants, this is the rule to start with:
get_node_constants is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every get_node_constants call is checked against it from then on.
