What get_scoring_rules does on Ad Lab
AI agents call get_scoring_rules to retrieve information from Ad Lab without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_scoring_rules is rated Low
Even though get_scoring_rules only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs get_scoring_rules safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ad Lab, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_scoring_rules, this is the rule to start with:
get_scoring_rules 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 Ad Lab, apply this rule, and every get_scoring_rules call is checked against it from then on.
