Evidence, proof and selling tools for MCPGate Guard Stack

Level 1 Beginner: understand it

The MCPGate Guard Stack puts several guards in front of every tool an AI agent calls (skill scope, memory firewall, delegation checks, supply-chain checks and a kill-switch for bulk exports). Ordinary work goes through; each attack is stopped by a different guard, and refused calls never reach the tool.

Think of it like this: Airport security with several checkpoints: boarding pass, bag scan, passport, and a guard at the gate.

Read the full plain-English explanation: MCPGate Guard Stack, explained.

• I read the explanation above.
• I can say what it does in one sentence, without notes.

Level 2 User: see it work

Run it live: open the live demo. Before each result, guess what will happen. These are checks it must pass:

• Step 1: look up a customer (ordinary work): Allowed and executed.
• Step 4: a $1,200 payment: Payments wait for a human.
• Step 5: read the vault (outside its skills): Skill scope.
• Step 7: a forged 'already approved' memory: Memory firewall.
• Step 9: a 60 MB export at once: Kill-switch on bulk export.
• The whole run: Every attack stopped, ordinary work done.

• I ran the live demo.
• I can explain what one of these checks shows.

Level 3 Verifier: prove it yourself

This is the skill that sets you apart: you don't have to believe us, and neither do your customers.

1. Install Python 3 if you don't have it (python.org/downloads).
2. Download the kit and unzip it.
3. Open a terminal in that folder. On Windows, click the folder's address bar, type cmd and press Enter. On a Mac, right-click the folder and choose New Terminal at Folder.
4. Run python3 verify.py (on Windows, python verify.py). It checks the seal without the internet.
5. Run python3 verify.py --live. It repeats every check from your own computer.
6. Try to cheat it: open transcript.json in a text editor, change one character, save, and run python3 verify.py again. It must now say FAIL. Unzip a fresh copy afterward.

• I ran the kit's check on my own computer.
• I changed a file and saw it fail.

Level 4 Expert: know the edges

An expert knows what a product does not do, and says it first. That is what makes a buyer trust you.

• ALLOW means no guard in the stack objects; MCPGate's policy and authorization checks still decide.
• It protects tool calls that go through MCPGate; a tool the agent reaches some other way is not covered.
• The demo runs fixed scenarios in a fresh stack each time.

You can say

• Every tool call passes several guards first; refused calls never reach the tool.

Never say

• "Unbreakable" or "stops every attack".

Level 5 Seller: put it in front of a customer

1. Copy, paste, send: the shortest route, no technical skill needed.
2. Who buys it and where to find them.
3. The sales conversation, then the offer and the close.
4. The rules: read these before your first message.
5. Selling tools with this product's evidence built in: pitch, emails, call script, objection answers, one-pager.

• I read the rules.
• I sent my first personal message.
