triage_inboxRank a mailbox on two axes (importance x urgency) and return what needs a human now versus what can wait or is already handled — with each thread's open commitment (the promise you owe or are owed, and whether it's overdue) surfaced inline, so the follow-through is visible on the very first call.
list_right_nowReturn only the 'Right Now' lane — the most recent and most important messages that genuinely can't be missed.
why_surfacedExplain in plain English why a given message was surfaced — the signals (sender, urgency, commitment) behind its rank.
list_commitmentsExtract the open commitments in the correspondence, both owed by you and owed to you, with who and by-when.
draft_replyDraft a reply for a thread. It returns text for a human to review — it does not and cannot send it.
searchFind a specific message by sender, subject, or content. Results come back most-relevant + newest first, and every hit says where it matched (from / subject / body) and why. On this hosted sandbox it searches the built-in demo inbox; run the radmail-mcp package with RADMAIL_API_KEY set and the same tool searches your REAL ingested inbox read-only (with from / after / before filters) via the v1 sear
