Set covenant rules using permit/forbid/require syntax. Each rule is a string like 'forbid delete_user' or 'permit read_data safe to read'.

Check whether an action is allowed or blocked by the current covenant rules.

Returns the full hash-chained audit trail of all compliance checks.

Independently verify the integrity of the hash-chained audit log. Detects any tampering.

Overview

What is Nobulex — Proof-of-Behavior Compliance Server?

A compliance server for AI agents that enforces behavior policies before execution, creates tamper-evident audit trails using hash-chaining (SHA-256 + Ed25519), and uses the covenant policy language to define allowed actions. It targets compliance with the EU AI Act Article 12 and enables independent third-party audits.

How to use Nobulex — Proof-of-Behavior Compliance Server?

Install via npm install @nobulex/mcp-server and configure it with a supported client such as Claude Desktop, Cursor, or VS Code. Declare agent policies using the covenant policy language to specify which actions are permitted or forbidden.

FAQ from Nobulex — Proof-of-Behavior Compliance Server

What does “pre‑execution enforcement” mean?

Forbidden actions are blocked before the agent runs them, rather than being logged afterward.

How are audit trails made tamper‑evident?

They use hash chaining with SHA‑256 and Ed25519 signatures, and any third party can verify the chain independently.

Which clients are supported?

The server works with Claude Desktop, Cursor, and VS Code.
