Market Data (x402) MCP server

Market Data MCP

<!-- mcp-name: io.github.r0dell/market-data-mcp -->

An MCP server that gives AI assistants and agents 32 paid market-data tools plus 5 free helper tools:

Exchanges: NYSE, Nasdaq, LSE, Xetra, SIX, Tokyo, Hong Kong, Shanghai, ASX, CME equity futures. Futures: ES, MES, NQ, MNQ, YM, MYM, RTY, M2K, FDAX, FDXM, FESX, FSMI. Macro data comes from the U.S. Treasury (public domain), the ECB (euro reference rates; source: ECB statistics) and the CFTC Commitments of Traders report (public domain).

How payment works

Each paid tool calls an HTTP API protected by x402. The server pays automatically in USDC on Base, using a wallet key you provide, and only:

• to the known wallets of these APIs (any other payee is refused),
• in USDC on Base mainnet,
• up to MAXUSDCPERCALL per call (default 0.05) and MAXUSDCPERSESSION per server start (default 1.00).

Without a key the free tools work and paid tools explain how to enable payment.

Use a separate, small wallet for X402PRIVATEKEY with only a few USDC on Base. Never use your main wallet.

No ETH is needed for gas; the x402 facilitator pays it.

Install (Claude Desktop, Cursor, any MCP client)

Requires uv. Add this to your MCP client config (Claude Desktop: Settings → Developer → Edit Config):

{
  "mcpServers": {
    "market-data": {
      "command": "uvx",
      "args": ["--from", "x402-market-data-mcp", "market-data-mcp"],
      "env": {
        "X402_KEY_FILE": "C:\\path\\to\\wallet.json",
        "MAX_USDC_PER_SESSION": "1.00"
      }
    }
  }
}

X402KEYFILE points to a file with the key (plain text or JSON with privatekey); alternatively set X402PRIVATEKEY directly. Without uv: pip install x402-market-data-mcp and use "command": "python", "args": ["-m", "marketdata_mcp"].

Then ask for example: "Is the NYSE open on 27 November 2026 at 18:00 UTC?", "What is the ES roll date in December?" or "Show the current US yield curve and the 2s10s spread."
