“Show me the tools PO6 Mailbox exposes.”
How secure is the PO6 Mailbox MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how PO6 Mailbox holds up.
Official endpoint
Operated by PO6 Mailbox (po6.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
OAuth sign-in — your account, your rules
You grant access from your own PO6 Mailbox account and can revoke it there at any time. gate never sees your password.
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 PO6 Mailbox adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
PO6 Mailbox's server requires OAuth, so it can't be scanned anonymously — connect it in gate and the same scan runs automatically before it goes live.
