Scored across 7 tools
Each tool targets a distinct resource and action: auth status, email search, folder listing, email retrieval, read state, calendar events, and reply drafts. No two tools appear to do the same thing, and the descriptions clarify the boundaries (e.g., search_emails returns metadata only, get_email returns body).
Most tools follow a consistent verb_noun pattern: search_emails, list_mail_folders, get_email, set_email_read_state, list_calendar_events, create_reply_draft. The outlier is outlook_auth_status, which uses a noun phrase and server prefix, breaking the verb-first convention slightly. Overall the pattern is still predictable and readable.
Seven tools is well within the ideal range for an email/calendar integration. Each tool covers a distinct core operation without unnecessary bloat, and the count matches the apparent scope of the server.
The tool surface covers the key email workflows: searching, reading, marking read/unread, listing folders, and creating drafts. Calendar events are read-only. Minor gaps exist such as no move/delete email or create calendar events, but these are not fatal for typical agent use cases, and draft creation (as opposed to sending) is a deliberate safety choice.
