List all access lists.
AI agents call npm_list_access_lists 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 performs a read-only operation that queries existing access lists. It has no capacity to create, modify, delete, execute code, or initiate financial transactions. The blast radius of misuse is minimal—an AI agent could at worst gather information about the nginx proxy manager's access control configuration, which does not cause data loss, system compromise, or irreversible changes.
From the tool's definition Tool name 'npm_list_access_lists' and description 'List all access lists' indicates a query operation that retrieves and enumerates data without modification or side effects.
Attacks that exploit this kind of access
List all access lists. 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_list_access_lists: 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_list_access_lists 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_list_access_lists 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_list_access_lists. 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_list_access_lists 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.
