# JP Business Opportunity Data Gateway — MCP Server
Remote [MCP](https://modelcontextprotocol.io) server exposing **deadline-driven Japanese public-sector business opportunity data** to AI agents, metered per call with the [x402 payment protocol](https://github.com/coinbase/x402).
- **MCP endpoint (Streamable HTTP, stateless):** `https://jp-biz-opportunity-62ko7b2uwa-an.a.run.app/mcp`
- Machine index: [llms.txt](https://jp-biz-opportunity-62ko7b2uwa-an.a.run.app/llms.txt) · API contract: [openapi.yaml](https://jp-biz-opportunity-62ko7b2uwa-an.a.run.app/openapi.yaml)
- Sibling gateway (corporate regulatory raw data): [jp-m2m-mcp](https://github.com/kodandy/jp-m2m-mcp)
| Tool | Dataset | Price |
|---|---|---|
| `list_opportunity_datasets` | Catalog lookup | **Free** |
| `search_open_tenders` / `get_tender_notice` | Open government tender notices (入札公告) — keyword, region, deadline | 0.05 USDC / call |
| `search_subsidies` / `get_subsidy_program` | Subsidy and grant programs (補助金・助成金) — eligibility, windows | 0.05 USDC / call |
| `search_sanctions` | Procurement sanction / suspension lists (指名停止), keyed by 13-digit corporate number | 0.05 USDC / call |
## 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.
