List NVD entries (sn_vul_nvd_entry). Filter by CVE id substring or minimum CVSS v3 base score.
AI agents call list_nvd_entries 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 a straightforward read operation against a vulnerability database (NVD). It retrieves and filters existing records by CVE identifiers and CVSS scores. No data is created, modified, deleted, or executed.
From the tool's definition Tool name and description indicate it 'List NVD entries' and 'Filter by CVE id substring or minimum CVSS v3 base score'. The verbs 'list' and 'filter' are read-only operations that retrieve vulnerability data without modification or execution.

List NVD entries (sn_vul_nvd_entry). Filter by CVE id substring or minimum CVSS v3 base score. 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_nvd_entries: 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_nvd_entries 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_nvd_entries 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_nvd_entries. 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_nvd_entries 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.
