List contacts for an account or search across all contacts
AI agents call list_csm_contacts to retrieve information from ServiceNow-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only queries to retrieve contact information from ServiceNow's Customer Service Management (CSM) module. It supports listing contacts by account or searching across all contacts, both of which are non-destructive retrieval operations. No data creation, modification, deletion, code execution, or financial operations are implied.
From the tool's definition Tool name 'list_csm_contacts' and description 'List contacts for an account or search across all contacts' indicate data retrieval operations with no modification or deletion capabilities.
