Each tool has a clearly distinct purpose: kipris_bibliography retrieves detailed bibliographic information for a single patent, kipris_build_query converts natural language to a search query, kipris_cpc_search searches by CPC code, kipris_free_search performs keyword searches across all fields, kipris_item_search allows field-specific searches, and kipris_search handles keyword searches in patent text. There is no overlap or ambiguity between these functions.

All tool names follow a consistent pattern: they start with 'kipris_' followed by a descriptive term (e.g., bibliography, build_query, cpc_search). This uniform prefix and snake_case structure make the tools easily identifiable and predictable.

With 6 tools, this server is well-scoped for patent search and retrieval. It covers key operations like detailed lookups, query building, and various search methods (CPC, free, item-specific), which is appropriate for the domain without being overwhelming or insufficient.

The tool set provides comprehensive coverage for patent search and retrieval, including query building, multiple search types, and detailed information access. A minor gap is the lack of explicit update or delete operations, but this is reasonable given the server's focus on querying a static patent database, and agents can work effectively with the provided tools.
