Consumer AI shield: bidirectional PII sanitization with encrypted local audit
vellaveto-shield-6.1.1 is not a library.

vellaveto-shield

Consumer AI shield — privacy-preserving protection for end-user MCP interactions.

Overview

Protects individual users when interacting with AI agents and MCP tools:

  • Bidirectional PII sanitization — strips personal data before it reaches tools, restores on return
  • Encrypted local audit — XChaCha20-Poly1305 encrypted audit trail with Merkle proofs
  • Session isolation — per-session PII and context isolation
  • Credential vault — encrypted credential storage with epoch-based rotation
  • Warrant canary — cryptographic proof that no covert access has occurred

Quick start

cargo install vellaveto-shield
vellaveto-shield --passphrase-env SHIELD_KEY -- ./your-mcp-server
