Scored across 3 tools
Each tool targets a distinct concern: listing chats, reading messages from a specific chat, and checking connection status. No functional overlap exists.
All tools use snake_case and verbs or nouns clearly. 'list_chats' and 'read_chat' follow verb_noun pattern; 'whatsapp_status' slightly deviates but is still clear and consistent in style.
With 3 tools, the server covers core read operations and status checking. The count is minimal but appropriate for a focused read-only WhatsApp interface.
The server lacks any write operations (e.g., send message, create chat). For a comprehensive WhatsApp tool set, these are significant gaps that limit agent functionality.
