Gets extensible enumerations.
AI agents call extensible_enum_get_enumerations 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 retrieves enumeration data from Dynamics 365 Commerce. The verb 'gets' and context of querying configuration/reference data indicates a read-only operation. No data is created, modified, deleted, or destroyed. The blast radius of misuse is minimal — an AI agent fetching enumerations cannot cause harm beyond information disclosure of what enumeration values exist in the system.
From the tool's definition Tool name contains 'get' and description states 'Gets extensible enumerations' — a retrieval operation with no modification or side effects.
