Japan RuleWatch tools (7)

write = sends, deletes, buys or posts
  • get_commercial_termsFree

    Free: return the current business-only commercial terms profile for a supported paid product. A status other than ready means Mainnet purchase is unavailable.

  • get_entry_packFree

    Paid: return the fixed Iya soba entry-preparation pack with sources, contacts, consultation text, unknowns, and next actions. It gives no customer-specific legal verdict. Japan Rule is not a government service.

  • get_evidence_packFree

    Return a concise evidence pack for one rule ID returned by search_rules. Includes official URLs, scope limits, and no legal-compliance verdict.

  • get_tourism_evidence_packFree

    Paid: return official Japanese primary-source URLs, evidence locations, checked dates, source versions, general requirements, traveler-screen checks, and re-check triggers for a complete supported A/B/C flow. This is informational evidence, not a legal verdict.

  • get_tourism_preflightFree

    Free: classify a Japan-bound hotel service flow into the supported A/B/C model, list missing facts, and flag manual review. It does not return primary-source evidence.

  • search_entry_casesFree

    Free: search the fixed Japan tourism entry-case catalog by region, activity, and language. Returns a model-case preview, key decision themes and what the paid preparation pack adds. It does not include source locations, contact routes, inquiry text or an action plan. Japan Rule is a private commercial service, not a government service.

  • search_rulesFree

    Search a small curated index of official Japanese sources about mail-order sales advertising. Use this before get_evidence_pack. Results are evidence pointers, not legal conclusions.

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:

If the Iya model case is relevant, call getcommercialterms 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:

  • searchrules and getevidence_pack: free ecommerce evidence lookup.
  • gettourismpreflight: free A/B/C service-flow classification, missing facts, and manual-review triggers.
  • gettourismevidence_pack: x402-paid tourism evidence pack for a complete supported A/B/C flow.
  • getcommercialterms: free commercial-terms profile and Mainnet sale-readiness for a paid product.
  • searchentrycases: free search for the Iya soba experience sample and its known gaps.
  • getentrypack: 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 getcommercialterms with jp-tokushima-miyoshi-iya-soba to read the business-only purchase conditions.
  2. Call getentrypack 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 businesspurchaseconfirmed: 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.
