Most tools have distinct purposes: get_person retrieves a single record, while get_ancestors, get_descendants, and get_relatives focus on different relationship types. However, get_relatives could be ambiguous with the more specific ancestor/descendant tools, as it might overlap in scope depending on what 'relatives' includes.

Four tools follow a consistent 'get_' prefix pattern (get_ancestors, get_descendants, get_person, get_relatives), which is clear and predictable. The outlier is call_api, which uses a different verb style, but this minor deviation doesn't significantly hinder readability or consistency.

With 5 tools, this is well-scoped for a genealogy-focused server. Each tool serves a distinct purpose in retrieving person data and relationships, and the count is neither too sparse nor overwhelming, fitting typical MCP server ranges.

The toolset covers core read operations for person data and relationships (get, ancestors, descendants, relatives), but lacks update, create, or delete capabilities, which might be expected for a full CRUD lifecycle in a genealogy context. The call_api tool provides flexibility but doesn't fill all gaps directly.
