AI agents call list_pipeline_cards to retrieve information from Keycrm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/queries pipeline card data from keyCRM. The verb 'list' combined with 'optional filters' is characteristic of read-only operations. There is no indication of creating, modifying, deleting, or executing actions. The blast radius of misuse is minimal—an AI could at worst retrieve information it shouldn't access, but cannot modify CRM state or trigger external operations.
From the tool's definition Tool name 'list_pipeline_cards' and description 'List pipeline cards with optional filters' indicate data retrieval with no modification or side effects.
