Put a human in the loop in 5 minutes.

Pick your stack, gate one irreversible action, and mint a receipt anyone can verify offline. No account needed to start; public read tools need no key.

1. Pick your path

{ "command": "npx", "args": ["-y", "@emilia-protocol/mcp-server"] }

import { withGuard } from '@emilia-protocol/langchain';
const safe = withGuard(tool, { action: 'payment.release' });

@guard("payment.release", context_fn=..., fetch=post)
def wire_transfer(amount, destination): ...

import { requireEmiliaReceipt } from '@emilia-protocol/require-receipt';
app.post('/release', requireEmiliaReceipt({ action: 'payment.release' }), handler);

2. The pattern (same everywhere)

Whatever the framework, the gate does one job: hold an irreversible action until it’s allowed, denied, or signed off by a named human.

const d = await guardAction({ action: 'payment.release', context });
if (d.deny)            throw new Error(d.reason);   // blocked outright
if (d.signoffRequired) await waitForHuman(d);       // a NAMED human approves
// ...otherwise proceed. Every approval mints a Trust Receipt.

3. Verify the receipt — offline, any language

A receipt minted anywhere checks anywhere, with no account and no network.
