Fetch category tree with optional parent filtering
AI agents call unopim_get_categories to retrieve information from UnoPim MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves category information from the UnoPim system. The verb 'Fetch' and the read-only operation of filtering a category tree confirms this is a Read operation. No data is created, modified, deleted, or executed. The blast radius of misuse is minimal as it only returns existing product information.
From the tool's definition Tool name includes 'get_' prefix and description states 'Fetch category tree with optional parent filtering' - both indicate data retrieval without modification or side effects.
