List all NPM settings
AI agents call list_settings to retrieve information from Nginx Proxy Manager MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves Nginx Proxy Manager configuration settings without creating, modifying, deleting, or executing any operations. It is purely informational and has minimal security impact even if misused, as it only exposes existing settings data without side effects.
From the tool's definition Tool name is 'list_settings' and description states 'List all NPM settings' — a retrieval operation with no modification or execution capability.

Register the Nginx Proxy Manager MCP server in PolicyLayer and add a rule for list_settings: 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 Proxy Manager MCP. Nothing to install.
list_settings 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_settings 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_settings. 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_settings is provided by the Nginx Proxy Manager MCP server (verybigsad/nginx-proxy-manager-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
