Japan Subsidy Search MCP — 日本の補助金・助成金検索

Give your AI agent real-time access to Japanese government subsidies and grants.

This MCP server searches the official Japanese government subsidy database (jGrants, operated by the Digital Agency) in real time. Perfect for AI agents serving SMEs, accountants, administrative scriveners (行政書士), and consultants working with the Japanese market.

Why this server?

Japan runs thousands of subsidy programs — national, prefectural, and municipal — but the data is fragmented and Japanese-only. Foreign AI tools are effectively blind to it. This server makes the entire live database queryable by any MCP-compatible agent (Claude, ChatGPT, custom agents).

Tools

search_subsidies

Search open subsidy programs by keyword and prefecture. Returns results sorted by application deadline with:

  • Days until deadline (computed automatically)
  • Maximum grant amount (formatted, e.g. "5億円" / "3,500万円")
  • Direct link to the official application page
  • When a prefecture filter yields zero hits, automatically reports matching programs in other regions so your agent can offer alternatives
get_subsidy_detail

Retrieve full details by subsidy ID: purpose, eligibility requirements, subsidy rate, application rounds with current deadlines, and contact information — converted from rich-text HTML into clean, LLM-ready plain text.

Example queries your agent can now answer

  • 「東京都の会社で使える省エネ補助金、締切が近い順に教えて」
  • "Find manufacturing subsidies open for applications in Osaka with deadlines this quarter"
  • 「創業支援の補助金で、従業員10人以下でも申請できるものは？」

Data source & freshness

Official jGrants API (Digital Agency of Japan). Data is fetched live on every call — no stale caches. This server adds normalization, deadline computation, region merging, and LLM-friendly formatting on top of the raw government data.

Pricing

Pay per tool call. One search or one detail retrieval = one event. No subscription, no minimum.
