Why lookup_lemmy is rated Low

The low severity reflects minimal blast radius—an agent retrieving public social media posts poses negligible risk. The cost structure (pay-per-call) does not elevate the category since no financial transactions are initiated by the tool itself.

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