Scored across 4 tools
Each tool has a clearly distinct purpose with no overlap: generate_qr creates custom-styled QR codes, generate_typed_qr produces structured data QR codes, list_frames enumerates frame templates, and list_types lists data types. An agent can easily differentiate between them based on their specific functions.
All tool names follow a consistent verb_noun pattern using snake_case: generate_qr, generate_typed_qr, list_frames, list_types. This uniformity makes the set predictable and easy to understand for an agent.
With 4 tools, this server is well-scoped for QR code generation and management. Each tool serves a clear, essential function without redundancy, making the count appropriate for the domain of QR code creation and information retrieval.
The tool set covers core QR code operations: generation (both styled and typed), and listing resources (frames and types). A minor gap exists in lacking update or delete tools for managing generated QR codes, but this is acceptable given the server's likely focus on creation and information.
