Security check

How secure is the SendLetter MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how SendLetter holds up.

✓ Verified directory serverSendLetter · sendletter.eu

Official endpoint

Operated by SendLetter (sendletter.eu) 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 SendLetter 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 SendLetter adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

SendLetter'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.

How it works

Connected in three steps

Connect your gate

Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.

Choose SendLetter in the gate directory. Sign in to your SendLetter account to grant access.

FAQ

Questions, answered

Is there an official SendLetter MCP server?

Yes — SendLetter operates its own remote MCP server at sendletter.eu. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.

How do I connect SendLetter to Claude or ChatGPT?

Add gate's gateway URL to your AI client once, then pick SendLetter in the directory. You sign in to SendLetter via OAuth to grant access. From then on, SendLetter's tools are available in every client you've connected to gate.

Do I need to host anything?

No. SendLetter runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.

Is the SendLetter MCP server safe to connect?

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.
