Genpark Agentic Commerce Agent Gateway Verifier Skill

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.

Run the native STDIO MCP server for Claude Desktop, Cursor, or Antigravity integration:

python mcp_server.py

3. Model Context Protocol (MCP) Config

Add to your claude_desktop_config.json or agent runner config:

{
  "mcpServers": {
    "genpark-agentic-commerce-agent-gateway-verifier-skill": {
      "command": "python",
      "args": ["path/to/genpark-agentic-commerce-agent-gateway-verifier-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.
