Search Gmail and Outlook, save drafts, manage email rules, and view email stats.
Scored across 17 tools
Several tool pairs overlap confusingly: read_mail vs read_thread both read threads, create_draft vs save_mail_draft both create drafts, browse_mail vs search_inbox vs open_mail all touch browsing/searching mail, and get_response_time_stats vs get_stats_by_period both return stats. Descriptions attempt to differentiate (e.g. read_mail for 'mail interface', read_thread for inbox threads), but boundaries remain fuzzy enough to risk misselection.
Every tool follows a clean snake_case verb_noun pattern (browse_mail, change_mail, create_rule, list_rules, update_rule, send_mail, search_inbox, etc.). The convention is applied uniformly across mail, rule, and stats tools with no camelCase or stylistic drift.
17 tools is slightly heavy but reasonable given three sub-domains (mail operations, rule CRUD, analytics) plus account listing. Each tool maps to a distinct action, though a couple (the two draft creators, the two stats tools) could be consolidated.
Coverage is solid: mail read/browse/search/send/state-change with draft handling, full rule lifecycle (create, get, list, update, delete), and analytics, plus account listing. Minor gaps remain: no tool to link/create an email account (despite descriptions telling users to link one), and no delete/discard message operation.
