Get details of a specific proxy host by ID
AI agents call get_proxy_host 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 retrieves configuration details of an existing proxy host. It performs a query/read operation without modifying, creating, deleting, or executing any infrastructure changes. The blast radius of misuse is minimal—an attacker would only gain visibility into proxy configuration, not the ability to alter the infrastructure.
From the tool's definition Tool name 'get_proxy_host' and description 'Get details of a specific proxy host by ID' indicate a retrieval operation with no side effects.
