Autonomous Multi-Channel Inventory Restock Predictive Balancer & PO Generator. Forecasts SKU sales velocity using exponential moving averages (EMA), calculates safety stock buffers ($SS = z \cdot \sigma_d \sqrt{L}$), dynamically computes reorder points (ROP), and synthesizes supplier Purchase Orders.

---

## 🌟 Key Features

- **100% Zero External Dependencies**: Runs entirely on the Python 3.9+ standard library.
- **Model Context Protocol (MCP) Standard**: Native support for JSON-RPC 2.0 `initialize`, `tools/list`, and `tools/call`.
- **Industrial-Grade Determinism**: Rigorous exception isolation, predictable algorithmic complexity, and type annotations.
- **Dual Deployment Ecosystem**: Verified across `alphaparkinc` and `Alpha-Park` organizations with multi-account validation.

## 🚀 Quick Start

### 1. Direct Python SDK Usage

```python
"""Example usage for AgenticInventoryRestockPredictiveBalancer."""
import sys
import json
from client import AgenticInventoryRestockPredictiveBalancer

sys.stdout.reconfigure(encoding='utf-8')

def main():
    print("=== Agentic Commerce Supply Chain Inventory Balancer Demo ===")
    balancer = AgenticInventoryRestockPredictiveBalancer()

    sales_7d = [45.0, 52.0, 48.0, 55.0, 50.0, 60.0, 53.0] # mean ~51.8 units/day

    print("\n--- 1. Evaluating SKU Run-Rate and Reorder Point (ROP) ---")
    eval_res = balancer.evaluate_sku_inventory(
        sku="ECOFLOW-DELTA-PRO-3",
        current_stock=180,
        lead_time_days=7,
        sales_history_7d=sales_7d,
        unit_cost_usd=1200.00
    )
    print(f"Mean Daily Demand: {eval_res['mean_daily_sales']} units")
    print(f"Safety Stock Buffer: {eval_res['safety_stock_units']} units")
    print(f"Reorder Point: {eval_res['reorder_point_units']} units")
    print(f"Current Stock: {eval_res['current_stock']} units (Days Left: {eval_res['days_of_inventory_remaining']})")
    print(f"Needs Restock: {eval_res['needs_restock']} (Status: {eval_res['restock_urgency']})")

    if eval_res["needs_restock"]:
        print("\n--- 2. Synthesizing Autonomous Supplier Purchase Order ---")
        po = balancer.generate_purchase_order(
            sku="ECOFLOW-DELTA-PRO-3",
            supplier_id="SUP-ECOFLOW-OFFICIAL",
            evaluation=eval_res
        )
        print(f"Created PO #{po['purchase_order_id']} for {po['ordered_quantity']} units")
        print(f"Estimated Total PO Cost: ${po['total_estimated_amount_usd']:,.2f}")

if __name__ == "__main__":
    main()

```

### 2. Run as Model Context Protocol (MCP) Server

Start standard JSON-RPC 2.0 server over `stdio`:

```bash
python mcp_server.py
```

Execute embedded test harness:

```bash
python mcp_server.py --test
```
