Get a category by ID.
AI agents call mealie_categories_get to retrieve information from Mealie 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 a single category record by its identifier. It performs a query operation that does not create, modify, delete, or execute any side effects. The blast radius of misuse is minimal—an attacker could only view category data, not alter or delete it.
From the tool's definition Tool name 'mealie_categories_get' and description 'Get a category by ID' indicate a retrieval operation with no side effects. The verb 'Get' and lack of any modification language confirm read-only behavior.
