Scored across 60 tools
Many tools are distinct, but overlaps exist: delete_media and delete_media_legacy are the same operation, send_message may be confused with the many send_* variants, and the abundance of get/set pairs for settings creates ambiguity about which tool applies to a given task.
Naming mixes verb-first and noun-first patterns, with inconsistent use of get/list/create/update/set/delete/patch and path-like suffixes (e.g., create_flows_flow_id_publish). While all snake_case, the lack of a uniform verb_noun pattern hurts predictability.
With 60 tools, this server is far beyond typical well-scoped MCP servers. Even for a comprehensive WhatsApp Business API, the surface is extremely large and likely to overwhelm agents with too many options.
The tool set covers a wide range of capabilities: messaging, media, groups, flows, templates, settings, webhooks, encryption, and calling. Minor gaps include reporting/analytics and limited message history beyond list_messages, but core workflows are well covered.
