List tracked customers with AI cost, MRR, and margin over a rolling window.
AI agents call margint_list_customers to retrieve information from Margint Ai without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries customer financial metrics (AI cost, MRR, margin) without modifying data or executing external operations. It is a straightforward Read operation with minimal security risk—an AI agent misusing this tool could only access existing cost/margin data, not alter business records or trigger financial transactions.
From the tool's definition Tool name 'margint_list_customers' and description 'List tracked customers with AI cost, MRR, and margin over a rolling window' indicate data retrieval only. No create, modify, delete, or execute operations are performed.
