JP Business Opportunity Data Gateway — MCP Server

Remote MCP server exposing deadline-driven Japanese public-sector business opportunity data to AI agents, metered per call with the x402 payment protocol.

• MCP endpoint (Streamable HTTP, stateless): https://jp-biz-opportunity-62ko7b2uwa-an.a.run.app/mcp

• Machine index: llms.txt · API contract: openapi.yaml

• Sibling gateway (corporate regulatory raw data): jp-m2m-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.
