MUNX Protocol & Airlock Visa Wiki

The MUNX Protocol is the foundational framework behind Multinex Identity. It provides cryptographic, verifiable identities to every autonomous agent operating within an enterprise network. Through the issuance of Airlock Visas, the protocol ensures that no action can be executed unless signed by an authorized agent tied directly to a human supervisor, eliminating the risk of rogue AI actions.

Alignment with the Core Product Set

The MUNX Protocol operates seamlessly alongside the other core modules of the Multinex platform to deliver comprehensive enterprise security:

• Multinex Shield: The AI firewall inspects prompts and payloads, relying on the MUNX Identity of the incoming request to apply role-based access control (RBAC).
• Multinex Runtime: Within the secure agent execution environment, operations are fundamentally gated by the Airlock Visa associated with the running agent.
• Multinex Identity (Powered by MUNX): This is the core engine for cryptographic accountability, issuing and rotating Visas to ensure zero-trust agent behavior.
• Multinex Audit: All ledger entries generated by the Audit module use MUNX signatures to immutably link system events back to the responsible agent and human supervisor.

Airlock Visa Architecture

An Airlock Visa is a short-lived, cryptographically signed token that grants an agent explicit permission to execute specific tasks. It functions as a dynamic lease.

Visa Components

• Agent ID: The unique identifier of the autonomous worker.
• Supervisor Principal: The human operator or organizational unit legally responsible for the agent's actions.
• Scope: The granular permissions (e.g., read-only access to a specific database, bounded API execution).
• Time-to-Live (TTL): A strictly enforced expiration window to prevent credential hijacking.

Identity Verification Contract

When an agent attempts to execute a tool or query a system, the Multinex Runtime intercepts the request and validates the associated Airlock Visa against the MUNX Protocol registry.

Agent Process -> Request Execution -> Multinex Runtime Intercept
  -> Validates Airlock Visa (MUNX Signature Check)
  -> Evaluates Scope against Multinex Shield Policies
  -> Action Authorized / Denied
  -> Logs to Multinex Audit Ledger

Observability & Auditing

Because every action requires a Visa, the resulting audit trails are irrefutable.

• GET /api/identity/visas: List active and expired Airlock Visas.
• POST /api/identity/revoke: Instantly terminate an agent's access by invalidating its Visa.
• REST tool responses from the Multinex platform include identity headers (X-MUNX-Agent-ID, X-MUNX-Visa-Status, X-MUNX-Supervisor).

Rollout Guidance

• Ensure all custom agents are registered in the Multinex Identity provider before deployment.
• Start with read-only scopes (e.g., scope: "db.read") to validate the Visa generation pipeline.
• Promote agents to write-access only when strictly necessary, and with minimal TTLs.
• Regularly review the Multinex Audit logs to monitor agent behavior and Visa utilization.
