search_rules
Advertised by the server during the last successful anonymous check.

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.

    }
  }
}
get_commercial_terms
Advertised by the server during the last successful anonymous check.

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

}
search_entry_cases
Advertised by the server during the last successful anonymous check.

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.

get_entry_pack
Advertised by the server during the last successful anonymous check.

get_tourism_preflight
Advertised by the server during the last successful anonymous check.

Advertised by the server during the last successful anonymous check.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http japan-rulewatch-mcp https://japan-rulewatch-mcp-mainnet.kadopi.workers.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add japan-rulewatch-mcp --url https://japan-rulewatch-mcp-mainnet.kadopi.workers.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable japan-rulewatch-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "japan-rulewatch-mcp": {
      "url": "https://japan-rulewatch-mcp-mainnet.kadopi.workers.dev/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration

}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start japan-rulewatch-mcp and inspect its tools.
VS Code configuration

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

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http japan-rulewatch-mcp https://japan-rulewatch-mcp-mainnet.kadopi.workers.dev/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
