Audit Trail

Wraps the PiQrypt Python library to give Claude cryptographic audit trails over MCP. Exposes four tools: stamp_event signs AI decisions with AISS-compliant signatures and chains them via previous_hash, verify_chain checks integrity across multiple events, export_audit generates compliance bundles in JSON or PQZ format, and search_events queries a local SQLite index by type and timestamp. Useful when you need tamper-proof logs for regulated environments like trading bots under SEC rules, hiring workflows under GDPR Article 22, or healthcare agents under HIPAA. Requires both the Python piqrypt package and Node runtime. Pairs with the optional Vigil dashboard for monitoring chain health and risk scores locally.
