## Setup

```bash
npm install -g kerdos-x402-mcp
```

Or run via npx (no install):

```bash
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`:

```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.
