Gets subcategories by channel and category id.
AI agents call categories_get_children to retrieve information from MCP Dynamics 365 Commerce Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves hierarchical product category data. It performs a read-only lookup operation without modifying, executing, or deleting any data. The action is limited to fetching existing subcategory information based on input parameters (channel and category id). Typical misuse would only result in accessing category information, which poses minimal risk in a commerce system context.
From the tool's definition Tool name 'categories_get_children' and description 'Gets subcategories by channel and category id' indicate a retrieval operation with no side effects.
