Measured tools (6)

• triage_inbox

  Rank 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.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_right_now

  Return only the 'Right Now' lane — the most recent and most important messages that genuinely can't be missed.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• why_surfaced

  Explain in plain English why a given message was surfaced — the signals (sender, urgency, commitment) behind its rank.

  Parameters:

  • message_id (required) — string — An id from triage_inbox, e.g. m_001.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_commitments

  Extract the open commitments in the correspondence, both owed by you and owed to you, with who and by-when.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• draft_reply

  Draft a reply for a thread. It returns text for a human to review — it does not and cannot send it.

  Parameters:

  • message_id (required) — string — An id from triage_inbox to draft a reply for.
  • guidance — string — Optional steer for the draft. Never sent — review-only.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• search

  Find 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 search API.

  Parameters:

  • query (required) — string — Words to find, matched against from / subject / body. Every word must appear somewhere in a message.
  • limit — number — Max hits to return (default 10).

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
