MCP server for orchard-data — pay-per-call market data for AI agents over x402 (USDC micro-payments on Base).

Setup

Payments need a small dedicated Base wallet holding USDC (a few dollars goes a long way at these prices). Use a burner wallet, never your main one.

{
  "mcpServers": {
    "orchard-data": {
      "command": "npx",
      "args": ["-y", "orchard-data-mcp"],
      "env": { "EVM_PRIVATE_KEY": "0x<burner wallet private key>" }
    }
  }
}

Without EVM_PRIVATE_KEY, list_products still works and paid tools explain setup.

How payment works

Each paid tool call: GET → HTTP 402 (payment requirements) → the server signs a USDC transfer authorization with your key → retries → JSON. Settlement is gasless for the buyer (EIP-3009 via the x402 facilitator). No account, no API key.
