List contracts in a tenant
AI agents call list_contracts to retrieve information from ACI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple data retrieval operation (list/query) with no side effects. It does not create, modify, delete, execute commands, or involve financial transactions. The 'list' verb is a standard indicator of Read category operations. The low severity reflects that misuse would only expose informational data about network contracts, not cause operational harm or data loss.
