What your AI can do with Attest
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “attest_scan”: Scan an agent payment endpoint (x402 / HTTP 402) and return a letter grade A to F with a safety verdict before paying.”
“Use “attest_guard”: Verify a live 402 payment offer at the moment of spend. Pass the EXACT offer you just received (url, payTo, amount, asset, network) and get.”
How secure is the Attest MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Attest holds up.
Official endpoint
Operated by Attest (attestagent.org) 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 Attest adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick Attest
Choose Attest in the gate directory. No sign-in needed.

Who runs the Attest MCP server?
The Attest MCP server at a glance
https://attestagent.org/api/mcpQuestions, answered
Is there an official Attest MCP server?
Yes — Attest operates its own remote MCP server at attestagent.org. 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 Attest to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Attest in the directory. No account or sign-in is needed. From then on, Attest's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Attest runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Attest 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.
Is it free?
Yes — you can get started with gate for free and connect Attest in minutes. No credit card required.
