List delivery service types (warehouse-door etc.) through Common/getServiceType (doc 1.9). Docs say to refresh monthly and point out the four core technologies: WarehouseWarehouse, WarehouseDoors, DoorsWarehouse, DoorsDoors.
AI agents call reference_get_service_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 retrieves static reference information about delivery service types from the Nova Poshta API. It queries and returns data without creating, modifying, deleting, or executing actions. The note about refreshing monthly and listing the four core service type technologies confirms this is purely informational data retrieval.
From the tool's definition Tool performs 'List delivery service types' and 'getServiceType' which are read-only data retrieval operations with no modification or side effects. The description explicitly indicates it is retrieving reference data about service types.

List delivery service types (warehouse-door etc.) through Common/getServiceType (doc 1.9). Docs say to refresh monthly and point out the four core technologies: WarehouseWarehouse, WarehouseDoors, DoorsWarehouse, DoorsDoors. It is categorised as a Read tool in the Novaposhta MCP Server, which means it retrieves data without modifying state.
Register the Novaposhta MCP server in PolicyLayer and add a rule for reference_get_service_types: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Novaposhta. Nothing to install.
reference_get_service_types is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the reference_get_service_types rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for reference_get_service_types. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
reference_get_service_types is provided by the Novaposhta MCP server (@shopana/novaposhta-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
