Get a setting by name.
AI agents call npm_get_setting 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 configuration settings without creating, modifying, or deleting data. It is a simple query operation that returns information about existing settings. The low severity reflects minimal blast radius—an AI agent misusing this tool would only gain access to existing configuration information, which may have some sensitivity but poses no destructive, financial, or system-altering risk.
From the tool's definition Tool name 'npm_get_setting' with description 'Get a setting by name' indicates a retrieval operation with no side effects. The verb 'Get' and context of querying settings align with Read category operations.
Attacks that exploit this kind of access
Get a setting by name. 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_setting: 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_setting 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_setting 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_setting. 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_setting 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.
