AI agents call get-media-type-schema to retrieve information from Mcp Dev 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 schema metadata from Umbraco CMS. It performs a read-only operation that returns information about media type structures without creating, modifying, deleting, or executing any operations. The description confirms it is informational in nature, intended to be used before creating media to understand the expected structure.
From the tool's definition Tool name 'get-media-type-schema' and description explicitly states it 'Gets the JSON Schema for a media type by Id' and 'Returns a JSON Schema describing the structure' — purely retrieval operations with no side effects.
