List available cargo types supported by Nova Poshta via Common/getCargoTypes (doc 1.8). Docs advise caching this API-key-protected directory monthly; expect values such as Parcel, Cargo, Documents, TiresWheels, Pallet.
AI agents call reference_get_cargo_types to retrieve information from Novaposhta without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a static reference directory of cargo types from Nova Poshta's API. It retrieves predefined values (Parcel, Cargo, Documents, etc.) without creating, modifying, deleting, or executing any operations. The API-key protection and caching recommendation confirm it is a safe, informational lookup. Severity is low because misuse poses no risk to data integrity or system state.
From the tool's definition Tool name contains 'get' and description states 'List available cargo types' - a retrieval operation with no side effects. The endpoint is described as a 'directory' that should be cached, confirming it is read-only reference data.
