Enables local AI agents to seal actions into a cryptographic hash chain, providing deterministic verification and tamper-evident audit trails in air-gapped environments.

DCL Evaluator

Version License Patent Platform MCP Offline LLMs

Cryptographic audit trail for AI agents. Powered by Leibniz Layer™

Every decision your AI agent makes — sealed, verified, auditable.

DCL Evaluator is the first implementation of Leibniz Layer™ — a cryptographic verification protocol for AI agent decisions. It brings deterministic, tamper-evident audit trails to any LLM-powered system.

Why DCL Evaluator

AI agents make decisions. Those decisions carry risk — legal, financial, reputational. Yet most AI systems are black boxes: no record of what was decided, why, or whether the decision was tampered with afterward.

DCL Evaluator solves this with a simple principle borrowed from cryptography: commit every decision into a hash chain. Modify any past record and the entire chain invalidates. Mathematical proof of integrity — no trust required.

Core capabilities

SHA-256 hash chain — every agent action cryptographically sealed
Merkle tree audit trail — tamper-evident by design
Deterministic policy engine — identical input = identical decision, 100% reproducible
Drift detection — statistical Z-test catches behavioural drift before it becomes a compliance failure
Multi-LLM support — Claude, GPT-4, Grok, Gemini, DeepSeek, Ollama (local, air-gapped)
MCP server — connect any agent in minutes via Model Context Protocol
Compliance reports — tamper-evident PDF export, ready for regulators
Offline-capable — runs fully air-gapped, zero data leaves your infrastructure
