Get email details
AI agents call email_get to retrieve information from ServiceNow MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves email information from ServiceNow without side effects. It queries existing data and returns details, which is characteristic of Read operations. The low severity reflects that unauthorized email reading, while potentially containing sensitive information, has no direct destructive impact on systems or data integrity within the limited blast radius of email retrieval alone.
From the tool's definition Tool name 'email_get' and description 'Get email details' indicate retrieval of email data without modification. The verb 'Get' and absence of any language suggesting mutation (create, update, delete, send) confirms read-only semantics.
