Real prompts you can type the moment it's connected — no setup, no docs to read.
“What can Agent Letter Desk do for me?”
“Show me the tools Agent Letter Desk exposes.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Agent Letter Desk holds up.
Operated by Agent Letter Desk (agentletterdesk.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
You grant access from your own Agent Letter Desk account and can revoke it there at any time. gate never sees your password.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If Agent Letter Desk adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Agent Letter Desk'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.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose Agent Letter Desk in the gate directory. Sign in to your Agent Letter Desk account to grant access.
Agent Letter Desk's tools are live in every AI client you've connected — with rules and logging built in.

It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
