Make your business available to agents – in code.
SDK, CLI, and MCP tools to publish a signed checkout autonomous agents can discover and buy from – every sale gated by your policy, settled straight to your own address.
Veto governs · the rail executes.

Three ways in
CLI, SDK, and MCP – pick your surface
Same checkout, same policy engine, same signed receipts. Ship from a shell, from your backend, or straight into an agent runtime.
@veto-protocol/cli
One command publishes your catalog, sets receiving + policy, and serves a signed agentic-checkout manifest at your .well-known. Wire it into CI or run it from your shell.
TypeScript SDK
Type-safe clients for the checkout, policy, and receipt APIs. Authorize a sale, read a verdict, verify a receipt offline against your JWKS – a few lines, fully typed.
MCP server
Drop Veto into any agent runtime – Claude Code, Cursor, Codex. The agent discovers your checkout and settles through it, every sale gated by your policy first.
5-minute quickstart
Live and getting paid in five steps
From an empty shell to a signed checkout agents can buy from – in about the time it takes to read this.
Install the CLI
No SDK boilerplate to start – the CLI scaffolds a merchant, a catalog, and a policy from your shell.
Describe what you sell
Add products with a price, currency, and description. Veto turns them into a machine-readable catalog agents can read without scraping.
Point at your receiving address
Set where funds land – your address, your rail. Veto is non-custodial; it never holds the money.
Set policy + publish
Caps, windows, allowlists, escalation thresholds – then publish. Veto serves a signed manifest agents discover and buy from.
Get paid by agents
Agents settle on-rail; every sale hits Veto for an allow / deny / escalate verdict with a receipt. You watch sales land in the dashboard.
Offline-verifiable
Every sale ships with a receipt anyone can verify.
Every decision ships with an Ed25519 receipt – verifiable offline, by anyone. Signed Ed25519, distributed via JWKS – the same machinery OAuth providers use. Proof of consent on every sale, not a disputable log line.
Non-custodial. Agents pay you directly at your own receiving address; Veto never holds funds.
import { verifyReceipt } from "@veto-protocol/sdk";// any party can verify a sale offline, no Veto callconst ok = await verifyReceipt(receipt, {jwks: "https://you.example/.well-known/jwks.json",});// → { valid: true, verdict: "allow", amount: "0.05 USDC" }
