Kronos Crypto Data MCP server

Kronos Crypto Data MCP Server

Real-time crypto market data for AI agents — derivatives (funding / OI / basis), liquidations, options IV, GEX, CEX premium, multi-source price, realized volatility, market-regime detection, and TradFi macro across 16 assets. An optional ML price forecast is available as a premium add-on.

x402-native: no API key, no signup. An autonomous agent discovers this server and pays per call in USDC on Base via the x402 micropayment protocol. There is no dashboard, no account, no API-key provisioning — just point a funded wallet at it and call. That is the one thing incumbent crypto-data MCPs (CoinGecko / CoinMarketCap / CoinGlass) cannot do.

• Data-first. 19 paid data tools covering derivatives, liquidations, options, macro, and screeners.
• Pay-per-call. Prices from $0.001 per call, settled on-chain in USDC — you pay only for what you use.
• Wallet-optional boot. The free getsample tool works with no wallet at all**.

Wallet-optional boot

The server boots and responds to initialize + tools/list without any environment variables set. Free tools (like getsample) work without a wallet. Paid tools return a clear error if BUYERPRIVATE_KEY is missing or the wallet has insufficient USDC — they never crash the server.

Quick start

Add the server to your MCP client config. For paid tools, set BUYERPRIVATEKEY to a wallet funded with USDC on Base. Omit the env block entirely to run only the free get_sample tool.

      "env": {
        "BUYER_PRIVATE_KEY": "0x<your-funded-wallet-private-key>"
      }
    }
  }
}

That's it — no signup, no API key. The first paid call triggers an on-chain USDC micropayment and returns both the data and the settlement tx hash.
