Tools & Capabilities Breakdown

Radmail MCP Tools (11)

triage_inbox

One round-trip over a batch: the Right Now lane + every open commitment + every hard-stop. The whole wedge in one call.

list_right_now

The can't-miss lane only — most-recent × most-important, each with why-surfaced. Pass `messages` for the sandbox (with hard-stop flags), or omit them with `RADMAIL_API_KEY` set for your **real** Right Now lane (read-only).

why_surfaced

Explain in plain English why a message surfaced — the signals behind its importance × urgency. Transparency, not a black box.

draft_reply

Draft the reply that discharges a commitment — **never** for a hard-stopped one (money / banking / first-contact stay human-only).

list_commitments

Open promises with their due window. Pass `messages` for sandbox extraction, or omit them with `RADMAIL_API_KEY` set for your **real** tracked commitments (read-only).
