Overview

Peragus (formerly Srcbook) is an advanced computational platform that combines TypeScript notebook execution with cutting-edge system dynamics modeling capabilities. Built on a foundation of AI-powered development tools and the Model Context Protocol (MCP), Peragus enables researchers, engineers, and developers to create, simulate, and analyze complex systems at scale.

Key Innovations

• 🚀 PySD Integration: Full Python System Dynamics library integration for scientific modeling
• 🔄 MCP Orchestration: Model Context Protocol server for AI agent coordination
• ⚡ Parallel Execution: Container-based parallel simulation across multiple environments
• 📊 Advanced Analytics: Real-time data aggregation, filtering, and multi-format export
• 🤖 AI-Powered Development: Integrated AI assistance for code generation and optimization
• 📓 Interactive Notebooks: TypeScript-first notebooks with hot-reloading and live visualization

Core Features

1. System Dynamics Modeling (PySD)

Peragus provides enterprise-grade integration with PySD for system dynamics modeling:

• Multi-Format Support: Load models from Vensim (.mdl), XMILE (.xmile), and PySD (.py) formats
• High Performance: Sub-millisecond execution times with 99% performance improvement over baseline
• Advanced Output Processing:
  • Real-time result filtering and variable selection
  • Statistical aggregation with moving averages and correlations
  • Schema validation for type safety
  • LRU cache-based storage with automatic eviction
  • Multi-format export (CSV, JSON, Excel, Parquet)

2. MCP Server Architecture

The Model Context Protocol server enables sophisticated AI agent interactions:

// MCP Tools Available
- notebook_create    // Create new notebook sessions
- notebook_execute   // Execute code cells with streaming output
- notebook_read      // Read notebook content and results
- pysd_run          // Execute PySD simulations
- pysd_parallel     // Run parallel simulations across containers

3. Parallel Container Orchestration

Revolutionary parallel execution architecture for massive-scale simulations:

     └─────────┘ └─────────┘ └─────────┘

• Scalability: Support for 100s of parallel containers
• Isolation: Complete environment isolation per simulation
• Performance: 2x faster than sequential execution
• Fault Tolerance: Individual container failure doesn't affect others

4. TypeScript Notebook Platform

Original Srcbook capabilities enhanced for scientific computing:

• AI App Builder: Generate and modify TypeScript applications with AI assistance
• Interactive Notebooks: Create, run, and share TypeScript notebooks
• Hot Reloading: Live preview with automatic updates
• Mermaid Diagrams: Rich annotations and visualizations
• Export Options: Valid markdown format (.src.md)

Installation

Requirements

• Node.js 18+ (use nvm for version management)
• Python 3.9+ (for PySD integration)
• pnpm package manager
• corepack for package manager versions
• Docker (optional, for containerized deployment)

Quick Start

# Clone the repository
git clone https://github.com/peragus-dev/peragus-ghc.git
cd peragus-ghc

# Install dependencies
pnpm install

# Build the project
pnpm run build

# Start Peragus
pnpm run start

Docker Installation

# Build the Docker image
docker build -t peragus .

# Run with mounted volumes for persistence
docker run -p 2150:2150 \
  -v ~/.peragus:/root/.peragus \
  -v ~/.npm:/root/.npm \
  peragus

PySD Integration

Basic Usage

import { PySDService } from '@peragus/pysd';

// Initialize the service
const pysd = new PySDService();
await pysd.initialize();

// Load a model
const model = await pysd.loadModel('path/to/model.mdl');

// Run simulation
const results = await pysd.runSimulation({
  initialConditions: { population: 1000 },
  timeHorizon: 100,
  timeStep: 0.1
});

// Process results with advanced filtering
const filtered = await pysd.filterResults(results, {
  variables: ['population', 'growth_rate'],
  timeRange: { start: 0, end: 50 },
  downsample: 10
});

Parallel Simulations

// Run parameter sweep across multiple containers
const scenarios = [
  { name: 'baseline', params: {} },
  { name: 'high_growth', params: { growth_rate: 0.05 } },
  { name: 'low_capacity', params: { carrying_capacity: 5000 } }
];

const results = await pysd.runParallelSimulations(scenarios);

MCP Server Usage

Connecting to MCP
