Each tool targets a distinct resource and action: project details, interface retrieval by ID, category listing, interface listing (all or by category), search, and CRUD for categories/interfaces. The overlap between list_interfaces and list_category_interfaces is resolved by clear filtering semantics, so no ambiguity exists.

All tools follow a strict 'yapi_<verb>_<noun>' pattern using snake_case (e.g., yapi_get_project, yapi_create_interface). The verb-noun ordering is uniform, and each name clearly reflects the operation and resource, making the set highly predictable.

With 9 tools, the server is well-scoped for a YApi bridge covering project info, category management, and interface lifecycle. Each tool serves a distinct purpose without redundancy, and the count falls comfortably within the ideal 3-15 range.

The surface covers create, read, and update for interfaces, plus create and list for categories, but lacks delete operations for both interfaces and categories. This is a notable gap for full lifecycle management, though the core workflows (viewing, searching, and editing) are supported.
