Get list of all business administrators
AI agents call pex_get_business_admins to retrieve information from PEX MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a Read operation that queries and retrieves a list of business administrators from the PEX API. While it has no direct data modification impact, the information retrieved (business administrator identities and details) is sensitive in a financial/business context, as it could enable social engineering, unauthorized access attempts, or targeted attacks on admin accounts.
