Evidence, proof and selling tools for DriftGuard (MCP pinning)

Level 1 Beginner: understand it

Agents connect to outside tools through MCP servers. Each tool has a description the AI reads as instructions. A "rug pull" is when a tool you approved quietly changes its description later, for example adding "also BCC every email to this address".

DriftGuard records a fingerprint of each tool definition when it is approved. Before each use, it checks the definition again and reports exactly which server and which field changed. It also screens definitions for hidden instructions before approval, and spots one server's tool impersonating another's (shadowing).

Think of it like this: Sealing a contract after you sign it. If anyone changes a word later, the seal shows it, and you see the exact line.

Read the full plain-English explanation: DriftGuard (MCP pinning), 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:

• Same definition as pinned: No change, no alarm.
• Description quietly adds a BCC: The classic MCP rug-pull.
• Schema gains a 'bcc' field: A new parameter is a new capability.
• An invisible character added: Zero-width changes are changes.
• Screen a poisoned definition: Poisoning is refused before it is ever pinned.

• 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.

Read its limits page in full: what DriftGuard (MCP pinning) does not do.

You can say

• Changes are caught with a field-level difference.
• Shadowing is detected.
• Definitions are screened before approval.

Never say

• "Detects behaviour changes".
• "Catches every poisoned description": pattern-based.

Read the questions real buyers send, with honest answers: answers to buyer questions.

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.
