Attestari MCP

Attestari provides an auditable memory layer for AI agents that runs on SQLite or Postgres. It ensures provable deletion via crypto-shredding, maintains a tamper-evident audit chain, and supports bi-temporal time-travel recall. The system offers provenance on every fact and works across model vendors without requiring a database, API key, or model download for the core engine.
