VITNA MCP

VITNA is a containment layer for AI agents that wraps stdio MCP servers. It intercepts risky tool calls, waits for human approval, and produces Ed25519-signed compliance receipts for agent actions. It supports guard mode for blocking unapproved actions and cooperative mode for pre-action checks, integrating with various agent frameworks.
