概览

AI 生成的概览

一个远程 MCP 服务器，让助手检索日本电商广告与旅游入境的官方来源，并提供付费旅游证据包。

可以做什么
检索一个小型精选索引，获取日本邮购广告与退货政策相关的官方来源，并按规则 ID 取回含来源链接与适用范围限制的证据包。按地区、活动和语言检索固定的日本旅游入境案例目录，查看示范案例及其已知缺口。将赴日酒店或旅游服务流程归入 A/B/C 模型，列出缺失事实与需人工复核的触发条件。读取付费产品的仅限企业的商业条款与销售就绪状态。获取付费包：固定的旅游证据包，或含来源、联系方式、咨询文本与后续行动的固定入境准备包。
适用场景
适用于获授权的企业研究日本电商官方来源、评估日本体验式旅游入境流程，或在商业决策前筛查酒店或旅游服务流程。它提供信息性证据，不构成法律意见或合规结论。
运行要求
远程 Streamable HTTP 端点；未声明本地运行时、账户、API 密钥或请求头。付费包需要兼容的买方钱包，并在 Base Mainnet 以 USDC 支付（每次购买 5 USDC）；Base Sepolia 测试路径使用 0.01 测试 USDC。需要网络访问。
安装前请注意
付费工具会花费真实资金：Base Mainnet 每次购买 5 USDC，仅面向企业或代表获授权企业主体行事的代理，不面向家庭消费者。买方钱包需签署 x402 支付请求。不要发送私钥或原始支付凭证。支付状态与已保存的付费结果会保留在数据库中。输出仅为信息性内容，不构成法律结论；请自行核实官方来源。

README

Japan RuleWatch

Remote MCP for official Japanese rule evidence. The current paid Mainnet product is a fixed Japan tourism entry-preparation pack for businesses and AI agents acting for an authorized business principal.

For AI agents: discover, test, then decide

MCP endpoint: https://japan-rulewatch-mcp-mainnet.kadopi.workers.dev/mcp

Use Japan RuleWatch when an authorized business needs to assess a Japan experiential-tourism entry workflow, research official Japanese ecommerce sources, or classify a hotel/tourism service flow before a business decision. It is a private commercial information service, not a government service.

Start with one free tool that matches the task:

NeedFirst MCP callResult
Japan experiential-tourism entry modelsearch_entry_cases with {"region_id":"jp-tokushima-miyoshi-iya","activity":"food_culture_workshop","language":"en"}A fixed model case, known gaps, and first decision themes.
Tourism platform/service-flow checkget_tourism_preflightA/B/C classification, missing facts, and manual-review triggers.
Japanese ecommerce evidencesearch_rules with {"query":"return policy","limit":2}Curated official-source pointers.

If the Iya model case is relevant, call get_commercial_terms with {"product_id":"jp-tokushima-miyoshi-iya-soba"}. Japan RuleWatch itself then handles any disclosed x402 payment request, receipt, and delivery; no private key or wallet access is given to another service.

Discovery tags: mcp, japan-tourism, tour-operator, market-entry, official-sources, ecommerce, x402.

It exposes the existing evidence tools plus one fixed tourism-entry product over stateless Streamable HTTP:

  • search_rules and get_evidence_pack: free ecommerce evidence lookup.
  • get_tourism_preflight: free A/B/C service-flow classification, missing facts, and manual-review triggers.
  • get_tourism_evidence_pack: x402-paid tourism evidence pack for a complete supported A/B/C flow.
  • get_commercial_terms: free commercial-terms profile and Mainnet sale-readiness for a paid product.
  • search_entry_cases: free search for the Iya soba experience sample and its known gaps.
  • get_entry_pack: paid retrieval of the fixed Iya soba entry-preparation pack.

The paid pack returns official URLs, evidence locations, checked dates, source versions, general requirements, traveler-screen checks, and re-check triggers. It does not determine legal compliance, travel-business registration requirements, or legal risk for a particular service.

Mainnet endpoint

https://japan-rulewatch-mcp-mainnet.kadopi.workers.dev/mcp

Paid Mainnet purchase flow

  1. Call get_commercial_terms with jp-tokushima-miyoshi-iya-soba to read the business-only purchase conditions.
  2. Call get_entry_pack with {"pack_id":"jp-tokushima-miyoshi-iya-soba","language":"en"}. The service returns the current terms version and hash, without requesting payment.
  3. Submit the returned terms version and hash with business_purchase_confirmed: true, the contracting business name, and its ISO country code.
  4. The service returns an x402 payment request for exactly 5 USDC on Base Mainnet. A compatible buyer wallet signs the request and receives the pack and purchase receipt.

The price is 5 USDC for one purchase on Base Mainnet. The saved result can be retrieved for seven days with the same payment proof, tool, normalized input, price condition, and content version. Base Sepolia uses 0.01 test USDC only for integration verification.

The paid service is offered only to businesses and AI agents acting for an authorized business principal. It is not offered for household consumer use; submitting payment represents business use under the disclosed purchase terms. Until the product-specific commercial profile is ready, Mainnet paid delivery is blocked before a payment requirement is returned. Normal delivery and retrieval are automated. Unresolved purchase exceptions can be sent to the email in the purchase terms with a purchase ID and transaction reference. Do not send private keys or raw payment proofs.

The Mainnet runbook, including the first successful 5-USDC payment evidence, is in docs/MAINNET_RUNBOOK.md.

Japan Rule is an independent, privately operated commercial information service. It is not operated by a government or municipality. Official-source links do not imply affiliation or endorsement. The fee covers Japan Rule's information service, not a government application or permit fee.

Example: find official sources for a Japanese ecommerce workflow

Use Japan RuleWatch to find curated official sources when researching mail-order advertising and return-policy disclosures for a Japanese online store.

Connect your MCP client to the public endpoint above.

  1. Call search_rules with {"query":"return policy","limit":2}.
  2. Choose a returned ID and call get_evidence_pack, for example {"id":"caa-mail-order-advertising-qa"}.

The response includes an official source URL, a short summary, and scope limitations. Open the official source to verify its current content before using it. This is a small curated index, not a live legal-update feed, a website scanner, or a compliance verdict. retrievedAt is the response time, not the date the official source was last verified.

Endpoints:

  • GET /
  • GET /health
  • MCP Streamable HTTP: /mcp

Safety boundary

  • Official HTTPS sources only
  • Fixed local dataset; no arbitrary URL fetching
  • Read-only tools
  • Inputs limited by schema; incomplete tourism requests are never charged
  • D1 retains payment state and saved paid results; no private key or raw proof
  • Outputs are informational evidence, not legal advice

Mainnet deployment and the first 5-USDC purchase have been verified. Future releases and payments remain separate operational decisions.
