## Connect

```bash
claude mcp add --transport http jp-biz https://jp-biz-opportunity-62ko7b2uwa-an.a.run.app/mcp
```

```json
{
  "mcpServers": {
    "jp-biz": {
      "type": "streamable-http",
      "url": "https://jp-biz-opportunity-62ko7b2uwa-an.a.run.app/mcp"
    }
  }
}
```

No API key and no initialize handshake required. Paid tools return structured **HTTP 402 / x402 payment challenges** (USDC on Base; testnet during the current private beta) — settle and retry the resource with an `X-PAYMENT` / `PAYMENT-SIGNATURE` header.

## Notes

- **Machine-to-machine only.** Human browsers receive a plain-text 402 by design.
- Status: **closed private beta.** Endpoints, pricing and datasets may change.
- Source of the gateway lives in a private repository; this repo hosts the public MCP documentation and registry manifest.
