List all SSL certificates in NPM
AI agents call list_certificates 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 returns existing SSL certificate data from Nginx Proxy Manager. It has no side effects, does not modify or delete data, and does not execute external operations. It is a straightforward information retrieval operation, making it a Read category risk with low severity since listing certificates poses minimal security risk compared to operations that could modify or delete infrastructure.
From the tool's definition Tool name 'list_certificates' and description 'List all SSL certificates in NPM' indicate a read-only query operation that retrieves certificate information without modifying, deleting, or executing any actions.
Attacks that exploit this kind of access
List all SSL certificates in NPM. It is categorised as a Read tool in the Nginx Proxy Manager MCP MCP Server, which means it retrieves data without modifying state.
Register the Nginx Proxy Manager MCP server in PolicyLayer and add a rule for list_certificates: 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_certificates 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_certificates 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_certificates. 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_certificates 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.
