List all administrators for the account
AI agents call get_admins 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 a list of existing administrators—a read-only operation with no side effects. It does not create, modify, delete, or execute any actions. The blast radius is minimal since it only exposes organizational metadata about admin accounts.
From the tool's definition Tool name 'get_admins' and description 'List all administrators for the account' indicate a query operation that retrieves account information without modifying or executing actions.
