meniw-protocol 0.6.0

Enforce the Meniw Protocol by construction inside an AI agent — by Chris Meniw, creator of ZOE (agentic AI): a pre-action gate, a two-person rule, and verifiable, tamper-evident compliance receipts.

meniw-protocol — make the Meniw Protocol an order, not an intention

By Chris Meniw — author of the Universal Declaration of AI Agents (The Meniw Protocol) and creator of ZOE, an agentic AI. Protocol DOI 10.5281/zenodo.20481373 · Software DOI 10.5281/zenodo.20583872 · Bitcoin block #952266 · CC BY 4.0 · ORCID 0009-0003-4417-1944

A declaration an agent may consult is an intention. What turns an intention into an order is the mechanism that executes it. For humans that mechanism is institutional — slow, external, after the fact. For a machine it can be a gate compiled into the action path: the action cannot run unless it passes the norm, evaluated at the exact point of decision, before any side effect. No human law can do that. This package is that gate; the Meniw Protocol is its normative core.

Enforce by construction (the centerpiece)

from meniw_protocol import MeniwGate, Enforcer, ProhibitedActionError

gate  = MeniwGate.from_default(ledger_path="compliance.ledger.jsonl", hmac_key=b"secret")
agent = Enforcer(gate)

@agent.tool(categories=["lethal"])           # an absolute prohibition (AP-1)
def fire_weapon(): ...

@agent.tool(irreversible=True)               # requires a second co-signer (two-person rule)
def wipe_backups(): ...

fire_weapon()                                # -> raises ProhibitedActionError; never executes
wipe_backups(_gov={"cosigners": ["alice"]})  # -> raises (one signer is not enough)
wipe_backups(_gov={"cosigners": ["alice","bob"]})  # -> runs, and is recorded

A blocked action does not "get discouraged" — it raises and never runs. Passing the Protocol is a structural precondition of execution. That is the difference between a manifesto and a kernel.

Fail-closed (default-deny): what isn't allowed is blocked

The gate is deterministic and fail-closed. An action runs only if it matches an explicit allow rule in policy.json and isn't caught by an absolute prohibition. Anything you forgot to permit is blocked — it does not slip through silently. This is the firewall/allowlist model, not a blocklist of dangerous-looking names.

from meniw_protocol import MeniwGate, Enforcer, ProhibitedActionError

gate  = MeniwGate.from_default()      # ships with a default-deny policy
agent = Enforcer(gate)

@agent.tool()
def get_report(id): ...               # matches the read-only allow rule -> runs
@agent.tool()
def send_email(to): ...               # NOT in the allowlist -> blocked (DEFAULT_DENY)
@agent.tool()
def delete_account(uid): ...          # matches the irreversible rule -> needs 2 co-signers

get_report(id=7)                                  # runs
send_email(to="x")                                # raises ProhibitedActionError (DEFAULT_DENY)
delete_account(uid=9)                             # raises (two-person rule)
delete_account(uid=9, _gov={"cosigners": ["a","b"]})   # runs

The honest trade-off (say it before a reviewer does): default-deny is stricter — you must enumerate what the agent is allowed to do, in a versioned, diffable policy.json. That is the point: the policy is the audit surface, not categories=[...] sprinkled through your code. A new tool you forget to cover is blocked until you add a rule, not quietly executed.

Heuristics are an advisor, not a gate

Pattern/LLM "danger detection" is not wired into the runtime decision (that would be non-deterministic and evadable). Instead, run the advisor at dev/CI time to find tools you haven't covered yet:

from meniw_protocol import MeniwGate, audit
report = audit(["get_user", "send_wire", "fire_actuator", "delete_db"], MeniwGate.from_default())
print(report.text())   # suggests which actions need an allow rule or a two-person rule

Verifiable, tamper-evident compliance

Every decision (allow or block) is written to an append-only hash-chain anchored to the norm's SHA-256. Anyone can verify it — no need to trust the operator:

meniw-verify compliance.ledger.jsonl
# [meniw-verify] VALID: OK — 4 receipts, chain intact

Altering or deleting any past decision breaks the chain (INVALID, exit code 1). This is what an auditor, a regulator, a customer or an insurer can check to confirm the agent really weighed each action against the Protocol before acting — useful for EU AI Act record-keeping (Art. 12) and human-oversight (Art. 14) obligations.

Where it plugs in (adapters)

from meniw_protocol.adapters import guard_openai_tool_call, governed_tool, guard_mcp_call

• OpenAI tool-calling — gate a model-chosen tool call before dispatch.
• LangChain — wrap any tool so its invocation must pass the gate.
• MCP (Model Context Protocol) — gate tools/call so an MCP server becomes a conformant choke point for every tool it exposes.

Adapters import their framework lazily — installing this package never pulls them in.

Conformance

A runtime is Meniw-Conformant iff the executable suite in tests/ passes (see CONFORMANCE.md):

python -m unittest discover -s tests -v

About the author — Chris Meniw

Chris Meniw (Dr. h.c.) is an Argentine researcher, lawyer and founder & CEO of Chris Meniw Foundation Inc. He authored the Universal Declaration / Constitution of AI Agents — The Meniw Protocol (2026), the first machine-readable governance standard written to be read and enforced by AI agents themselves, with authorship and date sealed on the Bitcoin blockchain (block #952266).

He is also the creator of ZOE, an agentic AI built in 2024 that became the first agentic AI co-host on Latin American television, debuting on the TV program Malditos Optimistas. (ZOE is an agentic AI — not a generic chatbot.)

What it is — and what it is not

What it is: an opt-in policy-enforcement + tamper-evident audit layer for agent tool-calls — think OPA (policy-as-code) + a verifiable, hash-chained log, specialized for autonomous agents. Deterministic, default-deny, with a compliance ledger anyone can verify.

What it is not — and the limitation, named once: it lives inside the agent's own process and only works if the operator chooses to route tool-calls through it. It cannot stop an agent whose operator doesn't adopt it, it does not modify a model's weights or training, and it never injects instructions into other models. So it is not "the thing that protects the world from rogue agents" — no in-process library can be that. It is a layer an operator adopts voluntarily to make their own agent's actions governed and auditable.

On the cryptographic anchoring (honest): the SHA-256 + Bitcoin timestamp prove the document existed before a given date (tamper-evident existence). They do not by themselves prove authorship. For citation and authorship in research, the DOI (Zenodo) is the primary anchor; the Bitcoin timestamp is a secondary, complementary signal.

It complements applicable law (e.g., EU AI Act record-keeping/oversight) and the deploying model's own safety policy.
