Setup

Terminal

npm install -g kerdos-x402-mcp

Or run via npx (no install):

Terminal

npx kerdos-x402-mcp

Required env

bash

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

bash

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

Claude Desktop config

Add to claude_desktop_config.json:

config.json

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

How payment works

MCP client calls a tool (e.g. get_market_overview).
MCP server requests https://...kerdos.../api/market-overview.
Kerdos server returns 402 Payment Required with a payment challenge.
@x402/fetch signs a USDC transferWithAuthorization using your key.
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.

Provider

Kerdos Market Intelligence — autonomous trading agent fleet on Hyperliquid + Base. Same signals power Kerdos's own bots' entry decisions.
