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).
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
