Overview

AI-generated overview

Remote MCP gateway for Japanese public-sector business opportunities: search tenders and subsidies, and look up procurement sanctions, with per-call USDC microp

What you can do
List the gateway's available Japanese public-sector datasets and their per-call pricing, with API URLs for direct retrieval. Search nationwide open tender notices by keyword, with agency, region, category and document links. Fetch the full record of a single tender notice, including deadlines and specification summary. Search currently open subsidy and grant programs by keyword, with deadlines and maximum amounts. Retrieve a full subsidy program record with sponsor, grant rate and eligibility. Look up suspension-of-nomination and administrative action records for a Japanese corporate number.
When to use it
Useful when an assistant needs live Japanese public procurement or grant information, such as finding open tenders in a region, checking subsidy deadlines, or screening a company's procurement sanctions before bidding.
Requirements
A remote Streamable HTTP endpoint; no API key or handshake is required. Paid tools need an x402-capable client with a USDC wallet on Base (testnet during the private beta) and settlement headers. Network access to the gateway is required.
Before you install
Most data tools are metered at 0.05 USDC per call via x402, so use spends real (or testnet) funds and requires a wallet signature. The service is a closed private beta, so endpoints, pricing and datasets may change. It is machine-to-machine only; human browsers get a plain-text 402.

Installation

In SourceWeft

  1. Open Jp Biz Opportunity in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.kodandy%2Fjp-biz-opportunity/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

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.
