api record

RadMail is pre-release. The engine is live in a test bed on two real businesses today; the commercial multi-tenant product is launch-gated. The MCP sandbox you connect to is real and runnable now (heuristic, in-memory, free, no credentials), but it is the sandbox engine — not the production multi-tenant engine.

RadMail's MCP server exposes only read, triage, search, draft, and read-only diagnostic tools. There is no tool that auto-sends money, changes banking details, or makes first contact with a new party — those stay human-only, forever, as a defense against business-email-compromise (BEC)…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 6 tools
2 open 4 never probed 2 of 6 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_commitments open 2h ago

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

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • list_right_now open 2h ago

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

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • triage_inbox unknown never probed

    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.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • why_surfaced unknown never probed

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

    mcp-tool

    {
  "type": "object",
  "required": [
    "message_id"
  ],
  "properties": {
    "message_id": {
      "type": "string",
      "description": "An id from triage_inbox, e.g. m_001."
    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • draft_reply unknown never probed

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

    mcp-tool

    {
  "type": "object",
  "required": [
    "message_id"
  ],
  "properties": {
    "guidance": {
      "type": "string",
      "description": "Optional steer for the draft. Never sent — review-only."
    },
    "message_id": {
      "type": "string",
      "description": "An id from triage_inbox to draft a reply for."
    }
  },
  "additionalProperties": false
}
    arguments 17 lines
  • search unknown never probed

    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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "query"
  ],
  "properties": {
    "limit": {
      "type": "number",
      "description": "Max hits to return (default 10)."
    },
    "query": {
      "type": "string",
      "description": "Words to find, matched against from / subject / body. Every word must appear somewhere in a message."
    }
  },
  "additionalProperties": false
}
    arguments 17 lines
_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
