AI agents call gandi_cert_list_tags to retrieve information from Gandi 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 existing tag metadata from a certificate resource. It performs a read-only operation that returns information without modifying, executing external operations, or deleting data. The blast radius of misuse is minimal—an agent could only over-query the API or expose tag information, neither of which poses significant risk.
From the tool's definition Tool name contains 'list' and description states 'List the operator-defined tags on a certificate' — a retrieval operation with no data modification or side effects.
