Market Data MCP

An MCP server that gives AI assistants and agents 16 paid market-data tools plus 5 free helper tools:

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 MAX_USDC_PER_CALL per call (default 0.01) and MAX_USDC_PER_SESSION per server start (default 0.10).

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

Use a separate, small wallet for X402_PRIVATE_KEY 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", "git+https://github.com/r0dell/market-data-mcp", "market-data-mcp"],
      "env": {
        "X402_KEY_FILE": "C:\\path\\to\\wallet.json",
        "MAX_USDC_PER_SESSION": "0.10"
      }
    }
  }
}

X402_KEY_FILE points to a file with the key (plain text or JSON with private_key); alternatively set X402_PRIVATE_KEY directly. Without uv: pip install https://github.com/r0dell/market-data-mcp/archive/refs/heads/main.zip and use "command": "python", "args": ["-m", "market_data_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."

Direct HTTP use

The same data is available as x402 HTTP APIs, listed in the Coinbase x402 Bazaar:
