Why lookup_dictionary is rated Low

The only side effect is a billable API call, which is inherent to the pay-per-call model and does not constitute a financial transaction risk (no funds are moved by the tool itself).
From the tool's definition Tool retrieves dictionary definitions (meanings, examples, phonetics) for English words with no side effects.

The rule that runs lookup_dictionary 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_dictionary, this is the rule to start with:
lookup_dictionary 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_dictionary call is checked against it from then on.
