list_effective_entities
AI agents call list_effective_entities to retrieve information from Mipiti MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list' operation pattern indicates data retrieval without modification or deletion. While the description is uninformative (lowering confidence), the naming convention and context as part of a security posture platform strongly suggest this tool queries or enumerates entities rather than modifying state.
From the tool's definition Tool name 'list_effective_entities' uses the verb 'list', which is a retrieval operation with no side effects.
