Setup

Or run via npx (no install):

npx kerdos-x402-mcp
Required env
EVM_PRIVATE_KEY=0x...   # YOUR private key (used to sign payment authorizations)

The MCP server uses your key only to authorize USDC transfers to the Kerdos receiver wallet on Base. Each tool call costs $0.01–$0.06.

Optional env
KERDOS_X402_BASE_URL=https://nonvisceral-eloisa-mousily.ngrok-free.dev

Claude Desktop config

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "kerdos": {
      "command": "npx",
      "args": ["kerdos-x402-mcp"],
      "env": {
        "EVM_PRIVATE_KEY": "0x..."
      }
    }
  }
}

How payment works

  1. MCP client calls a tool (e.g. get_market_overview).
  2. MCP server requests https://...kerdos.../api/market-overview.
  3. Kerdos server returns 402 Payment Required with a payment challenge.
  4. @x402/fetch signs a USDC transferWithAuthorization using your key.
  5. Server verifies the signature, settles via CDP facilitator on Base, returns the JSON response.

End-to-end latency: ~1-2 seconds per call. No interactive approval — payment happens transparently.
