TDQS
Scored across 38 tools
Most tools target distinct conversation actions or resources, but 'list_comments' is a duplicate alias of 'list_conversation_comments', creating ambiguity. Additionally, 'create_draft_conversation' and 'create_draft_reply' could be confused without careful reading, though descriptions mostly clarify.
Tool names follow a consistent verb_noun snake_case pattern, with clear use of prefixes like list_, get_, create_, update_, and un- for reversible actions. The alias 'list_comments' deviates from the standard 'list_conversation_comments' and 'upsert_contact' uses a less conventional verb, but overall the pattern is predictable.
With 38 tools, the server is heavily over-scoped for its purpose. Many tools are narrowly defined state changes (e.g., unarchive, unspam, unsnooze) that inflate the count beyond what is typically manageable, making the toolset feel bloated.
The conversation lifecycle is well covered, but there are notable gaps: no send-message operation, no ability to list or retrieve drafts, no CRUD for saved replies or mailboxes, and minimal attachment handling. These missing operations would require agents to work around incomplete functionality.
