List approval records (sysapproval_approver) for Vulnerability Response items — exception,
AI agents call list_vr_approvals 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 is a Read operation—it retrieves and queries approval records from ServiceNow's sysapproval_approver table for Vulnerability Response items. No side effects occur. However, severity is elevated to 'medium' rather than 'low' because approval records may contain sensitive information about security exceptions and remediation decisions that could inform attack planning or vulnerability intelligence if exfiltrated…
From the tool's definition Tool name 'list_vr_approvals' and description 'List approval records' clearly indicate data retrieval with no modification capability.

Register the ServiceNow- MCP server in PolicyLayer and add a rule for list_vr_approvals: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches ServiceNow-MCP. Nothing to install.
list_vr_approvals is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_vr_approvals rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
