概览

What is Japan Payments MCP?

A remote Model Context Protocol (MCP) server that lets AI agents create payment links and check payment status for Japanese payment rails — konbini (コンビニ決済), credit cards, PayPay, bank transfer, Pay-easy, LINE Pay, Merpay, au PAY, and Rakuten Pay. It works as a stateless translation layer routing through KOMOJU, a Japanese payment gateway with a hosted checkout page. The server is designed for developers building agentic applications that need to accept payments in Japan.

How to use Japan Payments MCP?

Add the endpoint https://mcp-jp.wishpool.app/mcp in any remote-MCP client (Claude Desktop, Claude Code, Cursor). On each request, send your KOMOJU secret key as the header x-komoju-secret-key. Two tools are available: create_payment_link (creates a JPY hosted-checkout link) and query_payment_status (checks if a session is paid).

Key features of Japan Payments MCP

  • Accept payments via konbini (convenience store) and 10+ Japanese methods
  • Pull-based payment status check — no webhook required
  • Stateless: never holds, moves, or stores funds or credentials
  • Bring your own KOMOJU secret key (test or live)
  • Zero runtime dependencies; Node ≥ 18 for local development
  • Remote MCP endpoint compatible with any MCP client

Use cases of Japan Payments MCP

  • AI assistants that need to generate a payment link for a customer to pay at a Japanese convenience store
  • Chatbot agents that collect payments via credit card or PayPay in yen
  • Automated workflows that verify payment completion without polling a third-party service
  • Multi-country payment scenarios using the sister servers for Taiwan, Korea, Indonesia, and India

常见问题

1

What does Japan Payments MCP actually do?

It provides two tools for AI agents: create a Japanese hosted-checkout payment link and check whether that session has been paid (captured or authorized). Funds flow directly from buyer to merchant via KOMOJU; the server never handles money.

2

How do I get credentials?

You need your own KOMOJU secret key. A test-mode key (`sk_test_...`) is free from the KOMOJU dashboard after switching to Test mode, and never moves real money. A production key (`sk_live_...`) is for live payments. There is no public demo key.

3

Does this server store any data?

No. It is a stateless translation layer with no database. It never holds, moves, or stores funds, credentials, or any other sensitive data.

4

How do I check if a payment succeeded?

Call the `query_payment_status` tool with the session identifier. It returns the current status (e.g., `captured` or `authorized`). The check is pull-based — no webhook configuration is needed.

5

What runtime does the server require?

The remote endpoint is always available. For local development, you need Node.js ≥ 18. The server has zero runtime dependencies.
