Why lookup_mdn is rated Low
This tool retrieves and queries publicly available technical documentation. It performs no data modification, deletion, execution of external code, or financial transactions. The cost is incidental billing for the lookup service, not a financial operation itself. Blast radius is minimal—results are informational only.
From the tool's definition Tool description states 'Search MDN Web Docs for a web-platform API or topic' — a pure search/query operation with no side effects. Example call is a simple query parameter. MDN Web Docs is public documentation.
Attacks that exploit this kind of access
The rule that runs lookup_mdn 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_mdn, this is the rule to start with:
lookup_mdn 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_mdn call is checked against it from then on.
