AI agents call search_vehicle_versions to retrieve information from StockSpark MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs querying and retrieval of vehicle version data with no side effects. It searches and returns information about vehicle makes, models, and versions without creating, modifying, or deleting data. The emphasis on presenting options to the user and asking for clarification further confirms it is a passive retrieval operation. This is a straightforward Read category tool with low severity impact.
From the tool's definition Tool description states it "Returns makes, models, or versions based on input" and "Smart search for vehicle versions." The progressive search mechanism retrieves data without modification.

Smart search for vehicle versions. Returns makes, models, or versions based on input. Progressive search: - No input → returns all makes - With make → returns models for that make - With make + model → returns matching versions IMPORTANT: When multiple versions are found, DO NOT automatically choose one. Present options to the user and ask them to specify their preferred version, engine size, or other distinguishing features before proceeding. It is categorised as a Read tool in the StockSpark MCP Server MCP Server, which means it retrieves data without modifying state.
