​
The Mock Engine

The mock_server.js file included in the developer toolkit acts as your local https://sign.sigilcore.com API. It validates bearer tokens, checks your agent’s intent against simple mock logic, and returns a dummy Ed25519 signature.

​
Installation & Setup

Navigate to your developer toolkit folder and initialize the Node environment: 
npm init -y
npm install express

​
Running the Engine

Start the mock firewall on Port 3000: 
node mock_server.js
You should see the following console output indicating the firewall is active: 
======================================================
🚀 Sigil Open Framework - Mock Engine Server Running
======================================================
Listening on: http://localhost:3000
Send POST requests to: http://localhost:3000/v1/authorize
Keep this terminal window open. As your agent requests Intent Attestations, you will see the engine’s real-time evaluation logs and policy violation rejections printed here.
