genpark-fintech-webhook-idempotent-replay-guard-skill

Python 3.9+ License MIT MCP Compatible GenPark AI Zero Dependencies

🌐 GenPark MCP Hub Showcase • 📦 Official Website • 📖 Documentation

📌 Overview & Capability

genpark-fintech-webhook-idempotent-replay-guard-skill is a deterministic, zero-dependency Python skill engineered with 100% production-grade functional parity for autonomous financial agents, real-time payment webhooks, immutable double-entry bookkeeping, and transaction fraud defense.

Executive Capability: Cryptographic payment webhook ingestion guard enforcing HMAC-SHA256 signatures, sliding replay tolerance, and atomic idempotency locking.

⚡ Key Highlights & Value

  • 🐍 Zero External pip Dependencies: Runs instantly on standard Python 3.9+ using built-in hmac, hashlib, and pure financial algorithms.

  • 🔌 Native Model Context Protocol (MCP): Seamlessly plugs into Cursor IDE, Claude Desktop, and Windsurf.

  • 🎯 100% Mathematical Ledger Integrity: Enforces strict Debits = Credits invariants, HMAC-SHA256 signature verification, and sliding-window fraud detection.

  • 🚀 Sub-Millisecond Financial Execution: Designed for high-throughput payment rails and real-time ledger accounting.
