Summary

Brings crypto market intelligence from Kerdos into Claude through 11 pay-per-call tools. You get BTC/ETH/SOL regime detection, funding rates, whale alerts, liquidation tracking, CVD, and composite sentiment. Each call costs $0.01 to $0.06 in USDC on Base, settled transparently via the x402 protocol using your EVM private key to authorize transfers. No subscriptions or API keys. Reach for this when you're building trading analysis workflows and want institutional-grade signals without upfront commitments. The same data powers Kerdos's own automated trading agents on Hyperliquid. Payment happens inline during tool execution with 1-2 second latency.

Setup

npm install -g kerdos-x402-mcp

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.
