WHAT IT DOES

What cdp_lookup_values does on CDP MCP Server

RISK

Why cdp_lookup_values is rated Low

This tool performs a data retrieval operation (lookup) on existing data within a data warehouse entity resource. It queries for distinct field values without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—at worst, an agent could exhaust query resources or access sensitive field data, but cannot modify data or trigger external actions.

From the tool's definition Tool name 'cdp_lookup_values' and description 'Lookup distinct values for a field in a DW entity resource' indicate a query operation that retrieves data without modification.
