AI agents call jpo_get_opd_family to retrieve information from IP-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to retrieve patent family data ('opd_family' likely refers to patent family records from JPO's database). The server is purely informational—querying Japanese patent data via API. The pattern of sibling tools and the 'get_' prefix indicate this is a read operation with no side effects.
From the tool's definition Tool name contains 'get_opd_family' suggesting retrieval of patent family information; all sibling tools on this server are read-only query operations (external_search_patents_by_keyword, jpo_fetch_full_record, jpo_get_*).
