Why lookup_joke is rated Low
This tool retrieves joke data from an API endpoint and returns it to the caller. No state is modified, no code is executed, and no data is created, updated, or destroyed. Despite the financial cost per call (which reflects the server's billing model, not the tool's capability), the tool itself performs only a read operation.
From the tool's definition Tool description states 'Get a random clean joke' — a pure retrieval operation with no side effects. The name 'lookup_joke' and description confirm it fetches and returns data without modifying, deleting, or executing external operations.
Attacks that exploit this kind of access
The rule that runs lookup_joke 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_joke, this is the rule to start with:
lookup_joke 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_joke call is checked against it from then on.
