Crypto Market Data MCP Server

crypto-market-data-mcp

Live crypto market data and Hyperliquid wallet reports as MCP tools for Claude, Cursor, Codex, VS Code and any MCP client. Your agent pays per call, in USDC on Base, from its own wallet (x402). There is no account, no API key and no subscription, and a call that fails is never charged.

Data refreshes every minute from 24/7 monitoring of Binance spot and futures, Hyperliquid and 31 news sources.

Connect without installing

Remote MCP server (Streamable HTTP, no sign-up): https://crypto-market-data.zafermemon87.workers.dev/mcp

Add it as a custom connector or remote server in Claude, ChatGPT, Cursor, VS Code or any MCP client. prices_free, sentiment_free and service_info are free. The other tools are paid per call with x402 over MCP, and clients built with @x402/mcp pay automatically.

Install

Claude Desktop, one click: download crypto-market-data.mcpb and open it. The wallet key is optional and is stored in your system keychain.

Claude Code:

claude mcp add crypto-market-data -e X402_PRIVATE_KEY=0x... -- npx -y crypto-market-data-mcp

Claude Desktop, Cursor or any MCP client (mcpServers config):

{
  "mcpServers": {
    "crypto-market-data": {
      "command": "npx",
      "args": ["-y", "crypto-market-data-mcp"],
      "env": { "X402_PRIVATE_KEY": "0x...", "X402_MAX_TOTAL_USD": "1.00" }
    }
  }
}

X402_PRIVATE_KEY is the key of a wallet that holds a little USDC on Base. No ETH is needed, because payments are gasless. Use a dedicated wallet with a small balance.

Spending limits

• X402_MAX_PER_CALL_USD (default 0.02, the price of a watch): no single payment above this.
• X402_MAX_TOTAL_USD (default 1.00): no more payments after this much in a session.

Without a key, prices and sentiment work free, with data refreshed every 15 minutes. service_info works too, and the other tools explain how to pay.

Other ways to use the same data

• HTTP API with x402: https://crypto-market-data.zafermemon87.workers.dev (OpenAPI at /openapi.json)
• Apify Store, paid by Apify account or agentic payments: https://apify.com/zaffy_93/crypto-market-data
• Verdicts instead of raw data (is a move, whale trade or headline real?): https://apify.com/zaffy_93/crypto-reality-check
