What is the Japan Subsidy Search MCP server?

Search Japanese government subsidies (official jGrants data): deadlines, amounts, eligibility. Exposed over MCP by the japan subsidy search mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

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.

Its toolset

Everything the assistant can do here goes through one of these:

  • search_subsidies — Search open subsidy programs by keyword and prefecture. Returns results sorted by application deadline with: - Days until deadline (computed
  • get_subsidy_detail — Retrieve full details by subsidy ID: purpose, eligibility requirements, subsidy rate, application rounds with current deadlines, and contact

Adding it to your client

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

When to reach for it

Among the AI and media services options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Japan Subsidy Search's toolset — search_subsidies, get_subsidy_detail — is a fair guide to whether it matches your workflow. It is maintained by easakura; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Japan Subsidy Search's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the japan subsidy search mcp server does with a few real requests.
