Search for customers by various criteria
AI agents call customer_search 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 customer information based on search parameters. It has no side effects—it does not create, modify, delete, or execute operations. It is a straightforward read operation consistent with customer management query functionality in a commerce system. The low severity reflects minimal blast radius: misuse would result in unauthorized information disclosure rather than data loss or financial impact.
From the tool's definition Tool name 'customer_search' and description 'Search for customers by various criteria' indicate a query/retrieval operation with no modification or deletion of data.
