## Executive Overview & Architectural Motivation

In 2025–2026, **Agentic Commerce** evolved from experimental in-chat discovery to standardized, machine-to-machine financial execution rails. Spearheaded by the **Universal Commerce Protocol (UCP)** (Google, Shopify, Walmart, Target), **Agentic Payment Protocols (AP2)** (Visa, Mastercard, Stripe), and retail **Agent Gateways**, autonomous AI agents now act as legally delegated consumer proxies.

This skill library distills the core mathematical logic and agent orchestration models powering the **GenPark Agentic Commerce Operating System**:

- **Machine-to-Machine Catalog Resolution**: Instantaneous multi-merchant availability and Pareto SLA optimization.
- **Cryptographic Financial Delegation**: Ephemeral tokenization with strict spend bounds and zero PAN exposure.
- **Game-Theoretic Bargaining**: Rubinstein alternating-offers automated negotiation with dynamic surplus splitting.
- **Zero-Dependency Protocol Parity**: Full native Model Context Protocol (MCP) compliance for agentic runtime integration.

## Quickstart & Usage

### 1. Direct Python Client Execution
```bash
python example_usage.py
```

### 2. Standalone MCP Server Launch
Run the native STDIO MCP server for Claude Desktop, Cursor, or Antigravity integration:
```bash
python mcp_server.py
```

### 3. Model Context Protocol (MCP) Config
Add to your `claude_desktop_config.json` or agent runner config:
```json
{
  "mcpServers": {
    "genpark-agentic-commerce-ap2-payment-delegation-vault-skill": {
      "command": "python",
      "args": ["path/to/genpark-agentic-commerce-ap2-payment-delegation-vault-skill/mcp_server.py"]
    }
  }
}
```

## Frequently Asked Questions (FAQ)

#### Q1: What makes GenPark Agentic Commerce Skills unique?
Engineered with **zero external dependencies** using pure Python standard library code. This ensures instantaneous cold starts, sub-millisecond execution overhead, and zero package version conflicts across diverse agent runtime environments.

#### Q2: How do I test this MCP server locally?
Run `python mcp_server.py --test` to verify MCP protocol discovery and tool schema negotiation.
