By 2026, AI agents don't just generate text — they call tools, move money and trigger workflows. Several guardrail approaches exist; they solve different layers. Here's an honest comparison, and where the open Meniw Protocol fits.
| Capability | Content/output filters (Llama Guard, NeMo) | Policy-as-code (OPA, OAP) | Meniw Protocol (meniw-protocol) |
|---|---|---|---|
| Block an unsafe tool call at runtime | partial | yes | yes |
| Enforcement by construction (action cannot execute) | varies | yes | yes (raises) |
| Verifiable, tamper-evident compliance receipts | no | logs only | yes (hash-chain) |
| Independent audit without trusting the operator | no | no | yes (meniw-verify) |
| Two-person rule for irreversible actions | no | custom | built-in |
| Open, citable standard with provable precedence | no | no | DOI + Bitcoin |
| Open source / free | mostly | yes | CC BY 4.0 |
This is a factual, complementary comparison — not a claim that the Meniw Protocol replaces these tools. It governs the agent's action layer and makes adherence provable. Use it alongside content filters and policy engines.
A prohibited action raises and never runs; irreversible actions need two co-signers; and every decision is written to a SHA-256 hash-chain anchored to the norm, so an auditor can verify it independently — useful for EU AI Act record-keeping (Art. 12) and human oversight (Art. 14).

What changes between countries is not the concept: it is which rule binds you today and what falls outside its reach. These pages handle that jurisdiction by jurisdiction, with the norm cited and the boundary stated.
