Attacks that exploit this kind of access
The rule that runs pdb_get_polymer_entity_instance safely
PolicyLayer is an MCP gateway: it sits between your AI agents and OrigeneMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pdb_get_polymer_entity_instance, this is the rule to start with:
pdb_get_polymer_entity_instance 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 OrigeneMCP, apply this rule, and every pdb_get_polymer_entity_instance call is checked against it from then on.
