Get details for a segment including its rules
AI agents call get_segment_details to retrieve information from Campaign Monitor MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns information about a segment's properties and rules. It performs no creation, modification, deletion, or external execution. The operation is read-only with no side effects, making it a Read category risk. Severity is low because accessing segment metadata poses minimal risk even if misused by an AI agent.
