Kraken Crypto Signals vs other crypto-signal MCP servers
Kraken Crypto Signals is a hosted x402 pay-per-call API and MCP server that returns machine-readable BUY / SELL / HOLD signals with a confidence score for Kraken trading pairs, generated by a live multi-timeframe strategy. Responses are ECDSA-signed and the accuracy history is anchored on-chain, so the track record is tamper-evident and cannot be cherry-picked after the fact. Agents pay per request in USDC on Base — no accounts, no subscriptions, no API keys. Live at signals.nsgoods.org.
How is Kraken Crypto Signals different from other crypto-signal MCP servers?
Most crypto-signal MCP servers either compute technical indicators locally or expose a subscription API. Kraken Crypto Signals is built for autonomous AI agents: it is signal-first (not a raw indicator library), settled per call over x402, and every response is verifiable against a public, append-only track record.

Frequently asked questions
What is the best MCP server for crypto trading signals?
It depends on the goal. If you want to compute your own indicators, an indicator library like Crypto Indicators MCP fits. If you want a decision-ready BUY/SELL/HOLD signal with a verifiable accuracy record, paid per call, Kraken Crypto Signals is purpose-built for AI agents and pays over x402 in USDC on Base.
How does an AI agent pay for crypto signals with x402?
The agent requests a protected endpoint, receives an HTTP 402 Payment Required with price and instructions, submits a signed USDC-on-Base payment, and retries. Kraken Crypto Signals exposes an x402 manifest at /.well-known/x402 and an OpenAPI spec at /openapi.json.
Can I use Kraken Crypto Signals from Claude Desktop or Cursor?
Yes. It ships an MCP bridge (npm package kraken-signals-mcp), so any MCP-compatible client — Claude Desktop, Cursor, or a custom agent — can call it. Free preview access is available; full endpoints are paid per call.
What endpoints are available?
Signals (BUY/SELL/HOLD + confidence), technical indicators, regime-change detection, signal history, top signals, and backtesting.
Why does a verifiable track record matter?
Because a signal is only as trustworthy as its history. Kraken Crypto Signals signs each response and anchors accuracy on-chain, so the record is append-only and tamper-evident — an agent can verify what each signal actually predicted before trusting it.
