claude mcp add japan-data --env EVM_PRIVATE_KEY=your-value -- npx -y @mameta/japan-data-mcp运行前请先填写空着的值。

@mameta/japan-data-mcp· MCP Registry:io.github.Mameta29/japan-data-mcp· transport: stdio
An MCP server that gives AI agents (Claude Desktop, Cursor, Cline, …) one-call access to the agentic-jp.com suite of Japanese data APIs. Every call is settled per-use over the x402 payment protocol — no account, no subscription, no API key.
| API | Tools | What it does |
|---|---|---|
| address | address_normalize, address_geocode, address_reverse_geocode, address_postal_code, address_parse | Japanese address normalization, geocoding, postal-code lookup, free-form parsing |
| furigana | furigana_convert, furigana_name_readings, furigana_classify | Reading conversion, name readings, text classification |
| transit | transit_station_status, transit_line_disruptions, transit_route_plan, transit_alternative_routes, transit_lines, transit_stations_search | Real-time rail delays + delay-aware route planning (ODPT) |
| diet | diet_member, diet_members_search, diet_minutes_search | National Diet members and full-text proceedings search |
| holiday | holiday_is_holiday, holiday_list, holiday_add_business_days, holiday_business_days_between | Public holidays + business-day math |
| weather | weather_forecast, weather_warnings, weather_areas | JMA forecasts and warnings |
| houjin | houjin_corporation, houjin_search, houjin_verify, houjin_kyb_report | Corporate-number (法人番号) registry — 5.78M corporations, one-call KYB report |
x402 is a buyer-pays protocol. This MCP server holds your wallet and pays each API call transparently — the agent never sees a payment prompt. Calls cost roughly $0.001–$0.10 each (mostly sub-cent), settled in USDC on Base.
EVM_PRIVATE_KEY to that wallet's key.Without EVM_PRIVATE_KEY the server still starts and lists every tool, but a paid tool call returns a clear "payment not configured" message — nothing is charged.
Security: the key in
EVM_PRIVATE_KEYcan spend that wallet's funds. Use a
dedicated wallet funded with only what you intend to spend — never a primary
wallet.
No install step — npx fetches and runs the server on demand.
Add to claude_desktop_config.json:
{
"mcpServers": { "japan-data": { "command": "npx", "args": ["-y", "@mameta/japan-data-mcp"], "env": { "EVM_PRIVATE_KEY": "0xYOUR_FUNDED_WALLET_KEY" } } } }
Without EVM_PRIVATE_KEY the server still starts and lists all 28 tools; the paid tools then return a clear "payments disabled" error instead of running. Add a USDC-funded wallet key to enable them.
Point the MCP client at npx -y @mameta/japan-data-mcp with the same EVM_PRIVATE_KEY env var. Transport is stdio.
git clone https://github.com/Mameta29/japan-data-mcp.git
cd japan-data-mcp npm install && npm run build
Once connected, just ask the agent in natural language:
