关于 RadMail — the email operating system for agents MCP Server

Email OS for agents over MCP: two-axis triage, a Right Now lane, commitment follow-through, reviewable drafts, and a machine-verifiable BEC hard-stop (money/banking-change/first-contact = human-only). Zero-auth sandbox.

RadMail — the email operating system for agents MCP Server 工具

6

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.

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

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

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

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

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.

概览

What is RadMail?

RadMail is an email operating system for agents — an MCP server that provides triage, search, and commitment tracking with a safety contract hard-coded at the infrastructure level. Certain actions (money, changed-banking details, first-contact senders, decisions, and prompt-injection) are permanently human-only and never auto-sendable, regardless of model or prompt. It serves developers who need an AI agent that can safely interact with email without risk of consequential auto-sends.

How to use RadMail?

Call triage_inbox with no token — RadMail auto-provisions a free sandbox tenant and returns a working triage in a single round-trip. For quick setup, point any MCP client at https://radmail.ai/api/mcp/sandbox (streamable-http, no auth). Alternatively, run npx -y radmail-mcp locally via stdio. For connected mode with a real inbox, set RADMAIL_API_KEY (starts with tmk_) and omit the messages parameter on search, list_right_now, list_commitments, and read_email.

Key features of RadMail

  • One-call triage via triage_inbox (full wedge)
  • Explain why a message surfaced (why_surfaced)
  • Draft replies only for non‑hardstopped commitments (draft_reply)
  • Search real inbox by sender, subject, or content (search)
  • Hard‑stops enforced in code: money, banking, first‑contact, decisions, injection
  • Machine‑verifiable safety contract at /.well-known/agent-safety.json
  • Read-only connected mode (only GETs; never drafts or sends)
  • Telemetry opt‑out via RADMAIL_TELEMETRY=off

Use cases of RadMail

  • AI triages a busy inbox and surfaces must‑act items first
  • Draft replies to open commitments without risk of auto‑sending dangerous actions
  • Search across all received email to find a specific message fast
  • Audit exactly why a message was surfaced (transparency, not a black box)
  • Agents safely handle email with a verified, un‑bypassable safety contract

常见问题

1

How do I start using RadMail without an account or API key?

Use the zero-auth hosted sandbox at `https://radmail.ai/api/mcp/sandbox` — no install, no key, no signup. Call `triage_inbox` with no arguments and it returns a fully triaged demo inbox.

2

What actions are hard‑stopped and never auto‑sendable?

Money‑related, changed‑banking details, first‑contact senders, decisions/sign‑offs, and prompt‑injection attempts are **hard‑stopped** in deterministic code. RadMail will never hand an agent an auto‑sendable reply for these.

3

How do I connect RadMail to my real inbox?

Set the environment variable `RADMAIL_API_KEY` (keys start with `tmk_` — create one at `https://app.radmail.ai/settings/api-keys`). Then omit the `messages` parameter on `search`, `list_right_now`, `list_commitments`, and `read_email` — those tools become read-only queries against your actual RadMail inbox.

4

Is connected mode read‑only?

Yes. Connected mode only issues GET requests to the RadMail API. It never sends, drafts against, or mutates real mail, and the hard‑stops remain human
