List Vulnerability Groups (sn_vul_vulnerability) — the task-based remediation entity
AI agents call list_vulnerability_groups 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 retrieves or queries vulnerability group data from the ServiceNow CMDB/vulnerability management system. Listing/reading data has no side effects, no destructive capability, and no ability to execute code or move money. The most restrictive action would be information disclosure of existing vulnerability data, which is low severity in a security catalogue context.
From the tool's definition Tool name 'list_vulnerability_groups' and description 'List Vulnerability Groups' indicate a retrieval operation with no side effects.

List Vulnerability Groups (sn_vul_vulnerability) — the task-based remediation entity. It is categorised as a Read tool in the ServiceNow-MCP MCP Server, which means it retrieves data without modifying state.
Register the ServiceNow- MCP server in PolicyLayer and add a rule for list_vulnerability_groups: 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_vulnerability_groups 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_vulnerability_groups 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.
Set action: deny in the PolicyLayer policy for list_vulnerability_groups. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_vulnerability_groups is provided by the ServiceNow- MCP server (tedorigawa001/servicenow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
