Gets configured extension package definitions.
AI agents call ext_pkg_def_get_definitions 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 extension package definitions, which is a read-only operation. It queries existing configuration data with no side effects, no data modification, no code execution, and no destructive capability. The operation is informational only, appropriate for AI assistants to understand system configuration. Low severity because misuse would only expose metadata about extension packages.
From the tool's definition Tool name 'ext_pkg_def_get_definitions' contains 'get' indicating retrieval. Description states 'Gets configured extension package definitions' — a query operation that retrieves configuration data without modification or execution of operations.
