Fetch the audit log.
AI agents call npm_get_audit_log to retrieve information from Nginx Manager without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves audit log data for inspection purposes only. Fetching logs is a read-only operation that does not create, modify, delete, or execute any actions. The blast radius of misuse is minimal—an attacker could only view historical logs, not alter system state or access lists.
From the tool's definition Tool name 'npm_get_audit_log' and description 'Fetch the audit log' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Fetch the audit log. It is categorised as a Read tool in the Nginx Manager MCP Server, which means it retrieves data without modifying state.
Register the Nginx Manager MCP server in PolicyLayer and add a rule for npm_get_audit_log: 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 Nginx Manager. Nothing to install.
npm_get_audit_log 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 npm_get_audit_log 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 npm_get_audit_log. 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.
npm_get_audit_log is provided by the Nginx Manager MCP server (kognar-ai/ngnix-manager-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
