Scored across 11 tools
Each tool targets a distinct operation: inbox management (create, delete, list), email retrieval (check, get, search, wait), sending, threading, and account info. No two tools overlap in purpose.
All tools follow a consistent verb_noun pattern in snake_case (e.g., create_inbox, get_email, search_emails), making the set predictable and easy to navigate.
11 tools cover the essential email workflows without redundancy or bloat. The count is well-balanced for an email server MCP.
Core email lifecycle is covered: create/delete inbox, send/receive/read/search emails, and threading. Missing operations like marking as read or updating email metadata are minor gaps.
