AI agents call porkbun_check_domain to retrieve information from Access without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves publicly available information about domain availability and pricing. It does not register, purchase, modify, or delete any domain; it only reads and reports information. While it is exposed through a credential management proxy, the action itself is purely informational.
From the tool's definition The tool description explicitly states it 'Check[s] domain name availability and registration price' and 'Returns whether the domain is available and the cost to register it.' These are query/retrieval operations with no side effects.
