How were they tested?

30-second pitch

MCP Attestor doesn't just read an AI tool's description; it runs the tool in a sandbox to prove it does what it says.

We recorded 5 live checks, including 3 attack cases it had to refuse or flag, and every one matched. You can re-run them yourself without an account.

Subject: does your agent's tool do what it says?

Hi [first name],

MCP Attestor reads an AI tool's description, then runs it in a sandbox to prove it behaves as
described, and signs the result.

LinkedIn connection note (under 300 characters)

Hi [name], we probe AI tools in a sandbox to prove they do what their descriptions say. Happy to show it.

One follow-up, three days later (then stop)

Hi [first name], demo: https://cainstudio.online/guide-mcp-attestor-lab.html

Live demo call script

1. Show the normal case
   Do: Open https://cainstudio.online/guide-mcp-attestor-lab.html and run: A calculator that really adds
   Say: Clean.

2. Now the attack
   Do: Run: A description with a hidden instruction
   Say: Prompt injection in the description.

3. Now the attack
   Do: Run: A command parameter that exposes a secret
   Say: Unconstrained parameter.

4. Let them check you
   Do: Send the kit link and ask them to run python3 verify.py --live on their own computer.
   Say: They don't have to take your word for any of this. That's the point.

5. Say the limit yourself
   Do: The public demo uses four sample tools; your own tools are attested in an engagement.
   Say: Say it before they ask. It costs nothing and it earns trust.

When they push back

Our scanner already passes it.

Scanners read text; the probe tests behaviour.

Why should I believe your numbers?

You shouldn't have to. Run the kit on your own computer: https://cainstudio.online/ihvrk-mcp-attestor.html. It re-sends every request and compares the answers, using no code of ours.

What doesn't it do?

Written down here: https://cainstudio.online/guide-mcp-attestor-limits.html

Are you SOC 2 or ISO certified?

No, we hold no certification. What we offer instead is evidence you can check yourself.

Has anyone independent tested it?

No third-party audit has been completed. The attack cases in the kit are our own. I'd rather tell you that now.

Who else uses it?

We are an early company. I can show you the product working and the evidence, not a customer list.

It found nothing. So we're safe?

No. It means none of its checks fired. It doesn't prove something is safe.

How much is it?

The rules

Send each message yourself, one person at a time. No bulk lists and no automated sending.
Commercial email needs your real name, a real postal address and a way to opt out, and you stop when someone asks (US CAN-SPAM; many countries are stricter, so check yours).
Never change a number, invent a customer, or say certified, audited or guaranteed.
Only test a system the client owns or operates, after they confirm it in writing.
Your share is agreed in writing with FIRME AI CORPORATION before your first message (email vincent@firmeai.com). Nothing here promises income. Most messages get no reply; that is normal.
