What your AI can do with Radmail MCP
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “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 t.”
“Use “list_right_now”: Return only the 'Right Now' lane — the most recent and most important messages that genuinely can't be missed.”
“Use “why_surfaced”: Explain in plain English why a given message was surfaced — the signals (sender, urgency, commitment) behind its rank.”
“Use “list_commitments”: Extract the open commitments in the correspondence, both owed by you and owed to you, with who and by-when.”
How secure is the Radmail MCP MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Radmail MCP holds up.
Official endpoint
Operated by Radmail MCP (radmail.ai) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Radmail MCP adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

The actual tools Radmail MCP exposes
Fetched live from the official endpoint and re-checked daily by gate — not marketing copy.
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 t
list_right_now — Return only the 'Right Now' lane — the most recent and most important messages that genuinely can't be missed.
why_surfaced — Explain in plain English why a given message was surfaced — the signals (sender, urgency, commitment) behind its rank.
list_commitments — Extract the open commitments in the correspondence, both owed by you and owed to you, with who and by-when.
draft_reply — Draft a reply for a thread. It returns text for a human to review — it does not and cannot send it.
search — Find a specific message by sender, subject, or content. Results come back most-relevant + newest first, and every hit says where it matched
