What blast_radius_script_dependents does on ServiceNow MCP Server
AI agents call blast_radius_script_dependents to retrieve information from ServiceNow MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why blast_radius_script_dependents is rated Low
This tool performs a read-only scan of configuration tables to find references to a named script artifact. It does not modify, execute, or delete anything — it is purely an analytical/query operation. Severity is medium because the scan touches potentially sensitive configuration and script data across the instance, and results could inform destructive actions like deletions or renames.
