AlgoVault × KuCoin — Build Verifiable AI Trading Agents

AlgoVault MCP gives your agent a composite verdict in one call — direction, confidence, regime, and cross-venue funding/sentiment context — backed by a publicly auditable record anchored to Base L2. Pair it with KuCoin Futures and your agent has both the analytics brain and the execution venue.

Provenance: OFFICIAL kucoin-universal-sdk — self-described as “the official SDK from KuCoin”, MIT, on npm and PyPI at 1.3.1, last pushed 2026-07-18. Note that every legacy per-language KuCoin SDK is archived, and several archived repos carry more GitHub stars than the live one — sort by activity, not popularity. Demo execution uses KuCoin’s order-validation endpoint (POST /api/v1/orders/test) with KUCOIN_DRY_RUN=true + MAINNET_BLOCKED=true wrapper guards. Verified 2026-07-21.

⚠️ KuCoin has no sandbox — read this before you start

KuCoin retired its sandbox on 2023-07-10 (announcement), promising to “present the Sandbox Environment in a new form later.” As of 2026-07-21 that has not materialised: every historical sandbox host (api-sandbox-futures.kucoin.com, api-sandbox.kucoin.com, openapi-sandbox.kucoin.com) returns NXDOMAIN, and the current official SDK contains zero sandbox or testnet references.

This tutorial therefore does not claim a testnet. It is built on POST /api/v1/orders/test, which validates an order payload — signature, symbol, sizing, permissions — and returns without placing a trade. Be precise about what that does and does not give you:

  • ✅ It confirms your credentials, signature construction, and parameters are correct.
  • ❌ It does not fill, does not simulate a matching engine, and does not give you simulated balances or PnL.

If you need a venue with a genuine order-placing testnet, this repo’s BingX, Aster, and Binance tutorials cover ones that have one.

Access note: KuCoin closed all US accounts effective 2025-01-23 and restricts access from US IP addresses.

What you’ll build (90s read)

A runnable Node.js agent that:

  1. Calls AlgoVault MCP for a composite verdict on a chosen asset + timeframe.
  2. Reads the verdict’s call, confidence, regime, and reasoning fields.
  3. Hands the verdict to KuCoin Futures’ order-validation endpoint when the agent’s pre-configured policy fires — proving the whole path works without placing a trade.

Every code path is validation-only — no order is ever placed.

Prerequisites (4 items)

  1. Node.js ≥ 22 (node --version to check).
  2. AlgoVault skills plugin installed:
    claude plugin install AlgoVaultLabs/algovault-skills
  3. KuCoin account with a Futures API key (API key + secret + passphrase, from the API management console). The demo runs read-only out of the box; supplying credentials unlocks the validation step.
  4. Optional — the official SDK, if you prefer it to raw fetch:
    npm install kucoin-universal-sdk

Demo: Confidence-filtered order validator on XBTUSDTM (≤80 lines)

// examples/kucoin/demo.mjs (excerpt — see file for full source)
import crypto from 'node:crypto';
import { getAlgoVaultVerdict } from '../_shared/algovault-helper.mjs';

const MAINNET_BLOCKED = true;
const KUCOIN_FUTURES_BASE = 'https://api-futures.kucoin.com';

if (process.env.KUCOIN_DRY_RUN !== 'true') {
  throw new Error('KUCOIN_DRY_RUN=true required — this demo is validation-only.');
}

const verdict = await getAlgoVaultVerdict({ coin: 'BTC', timeframe: '1h' });

if (verdict.call === 'BUY' && verdict.confidence > 70) {
  // /orders/test validates the payload. It does NOT fill.
  await signedPost('/api/v1/orders/test', {
    clientOid: crypto.randomUUID(), symbol: 'XBTUSDTM',
    side: 'buy', type: 'market', size: 1, leverage: 1,
  });
}

Run it:

KUCOIN_DRY_RUN=true node examples/kucoin/demo.mjs

Expected output (last 3 lines):

[kucoin futures | timestamp HTTP 200 | XBTUSDTM listed]
[policy | fires=false (call===BUY && confidence>70)]
=== NO ORDERS PLACED (validation endpoint only) ===

Walkthrough (line-by-line — neutral narration)

The script does three things in order:

  1. Fetch the AlgoVault verdict. The helper opens an MCP session against https://api.algovault.com/mcp, calls get_trade_call with {coin, timeframe}, and returns the parsed call / confidence / regime / reasoning payload. Free tier covers up to 20 calls/day per IP.

  2. Apply the agent’s policy. When the verdict satisfies a pre-configured policy (e.g. the agent’s policy fires when confidence > 70 AND call === 'BUY'), the script proceeds to the validation branch. The policy lives entirely in your code — AlgoVault returns the analytics; the agent decides.

  3. Validate against KuCoin. The signed request goes to POST /api/v1/orders/test on the futures host. The script aborts immediately if KUCOIN_DRY_RUN is not set — and because the real POST /api/v1/orders endpoint appears nowhere in the file, there is no code path that can place an order.

3 Recipes

Recipe 1 — Regime-gated entries

Call get_market_regime before acting. When the regime is RANGING, a trend-following agent can skip the entry rather than paying the spread on a chop signal.

Recipe 2 — Get the KC-API headers right

KuCoin’s auth is a five-header family: KC-API-KEY, KC-API-SIGN, KC-API-TIMESTAMP, KC-API-PASSPHRASE, and KC-API-KEY-VERSION. The detail that trips people up is that from key version 2 onward the passphrase is not sent in plaintext — it is itself base64(HMAC-SHA256(passphrase, apiSecret)). The current SDK sends KC-API-KEY-VERSION: 3. A v1-era snippet copied from an old blog post will fail authentication.

Recipe 3 — Promote from validation to live, deliberately

Because /orders/test and /orders take an identical payload, promoting is a one-line change — which is exactly why it should be a deliberate, reviewed one. Keep the endpoint in a single constant, gate it behind an explicit environment flag, and pair the switch with a per-order size cap and a kill switch before it ever runs unattended.

⚠️ Production setup (real-money)

The demo above never places an order. Real-money setup requires:

  • KYC completion on KuCoin, and confirming the service is available in your jurisdiction.
  • Production API keys with only the permissions your agent needs (no withdrawals, IP-allowlisted).
  • Risk controls: per-order size cap, daily loss limit, kill switch.
  • Position monitoring: a separate agent or watchdog that tracks open positions independently.
  • The correct base host — futures is api-futures.kucoin.com, which is not the spot host api.kucoin.com.

See examples/kucoin/README.md for the full real-money checklist. AlgoVault provides analytics; your agent and your risk policy decide what (if anything) to execute.

Why AlgoVault?

  • Composite verdict, not raw indicators. One JSON response replaces 26-indicator vote-counting.
  • Cross-venue intelligence. Funding spreads, regime, and sentiment fused across 12 exchanges — not derivable from any single-venue API.
  • Publicly verified. Every signal anchored to Base L2 via Merkle proof. Verify before you subscribe.
