genpark-jwt-hmac-sha256-token-attestation-skill

Python 3.9+ License MIT MCP Compatible GenPark AI Zero Dependencies

⚡ Overview & Architectural Significance

genpark-jwt-hmac-sha256-token-attestation-skill delivers zero-dependency, mathematically sound cryptographic attestation, zero-knowledge verification, and cybersecurity primitives engineered strictly using Python 3.9+ standard library.

🌟 Key Architectural Capabilities

  • Zero External Dependencies: Operates exclusively via pure Python (hashlib, hmac, secrets, time, json). Zero OpenSSL or C binding failures.

  • Enterprise Security Invariants: Implements formal SHA-256 Merkle root verification, RFC 7519 JWT HMAC-SHA256 signature parsing, 3-pass Schnorr zero-knowledge identification, constant-time equality validation, and sliding-window nonce replay protection.

  • Native Anthropic MCP Protocol: Compliant with standard JSON-RPC 2.0 stdio MCP specifications for Claude Desktop, Cursor, and Windsurf.

🚀 Quickstart & Standalone Execution

Local Python Client Usage

from client import JWTHmacSha256AttestationValidator

# Initialize engine
engine = JWTHmacSha256AttestationValidator()

# Execute self-testing benchmark suite
result = engine.benchmark_jwt_attestation()
print("Execution Result:", result)

🔌 One-Click MCP Integration (Claude Desktop / Cursor)

Add to your claude_desktop_config.json or cursor.json:

{
  "mcpServers": {
    "genpark-jwt-hmac-sha256-token-attestation-skill": {
      "command": "python",
      "args": ["-u", "/path/to/genpark-jwt-hmac-sha256-token-attestation-skill/mcp_server.py"]
    }
  }
}

    Enables AI agents to construct SHA-256 Merkle trees and generate/verify inclusion proofs, validate JWT HMAC-SHA256 claims, run Schnorr zero-knowledge identification, and enforce constant-time secret comparison with nonce replay protection for tamper-evident state attestation. It runs as a zero-dependency, stdlib-only MCP stdio server for clients such as Claude Desktop, Cursor, and Windsurf.

    Enables agents to cryptographically attest and verify identity and execution state through RFC 7519 JWT HMAC-SHA256 signature checks, claims and expiration validation, constant-time secret comparison, SHA-256 Merkle inclusion proofs, Schnorr zero-knowledge identification, and sliding-window nonce replay protection. It runs as a zero-dependency Python MCP server over stdio, so it can be attached to Claude Desktop, Cursor, or Windsurf without external libraries.
