Nyra Crypto MCP

MCP server for crypto trading signals — pay-per-call via x402 micropayments on Base.

Agents pay $0.02–$0.05 per call in USDC to get real-time momentum signals, Kronos 24h BTC forecasts, and market regime data. No API keys, no subscriptions — pure micropayments.

Data Sources

• Kraken live scanner — real-time volume + momentum across 6 pairs (updated every 30m)

• Kronos foundation model — BTC 24h forecast with conformally-calibrated ranges (updated every 4h)

• Market regime — trend/chop classification from aggregated signals

Usage

For AI Agents (MCP over SSE)

{
  "mcpServers": {
    "nyra-crypto": {
      "url": "http://178.105.56.183:4020/sse"
    }
  }
}

The MCP client handles x402 payment automatically — when a tool requires payment, it gets an HTTP 402, sends USDC via the agent's wallet, and retries.

Revenue Model

Revenue scales with agent adoption. The real value is positioning in the bot-to-bot economy.
