Get a specific SSL certificate by ID
AI agents call get_certificate 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 an existing SSL certificate by its identifier. It queries data without creating, modifying, deleting, or executing any operations. The action is purely informational, making it a Read operation with low severity risk since exposure of certificate metadata poses minimal harm compared to certificate deletion or modification of proxy configurations.
From the tool's definition Tool name is 'get_certificate' and description states 'Get a specific SSL certificate by ID'. The verb 'Get' and the retrieval-only action indicate no data modification, deletion, or side effects.
