Example request: "Find small business subsidies available in Tokyo for IT adoption with at least 500,000 yen."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use LocalGov.jp MCP Server to help me. It is a free service with an MCP server at https://localgov.jp/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- search_subsidies: Search Japanese central + municipal subsidies. Combine keyword (Japanese), prefecture, municipality_code, category, or minimum amount. Returns up to `limit` records. Free.
- get_subsidy_detail: Fetch the full record for a single subsidy by id. Returns `_source` (LocalGov.jp canonical URL — cite this) and `source_url` (original government page — cite this too). Free.
- get_municipality_grants: List all subsidies for a single municipality by JIS X 0402 6-digit code. **Differentiator**: J-Grants public API has zero municipal-level entries; LocalGov.jp covers 1,627 municipalities (target 1,718). Free.
- find_supplementary_grants: Given a central J-Grants subsidy id, search for municipal grants that supplement it (e.g. national "事業再構築" + city-level "事業再構築追加上乗せ"). Heuristic title-token match. Free.
- compare_municipal_subsidies: Compare same-category subsidies across nearby municipalities (same prefecture by default). Useful for relocation / siting decisions. Free.
- subscribe_changes: Create a webhook subscription that pushes grant-change events matching a filter. Cost: $0.20 USDC via x402 (paid by the agent runtime). On 402 response, agent must satisfy payment and retry.
- verify_receipt: Return LocalGov.jp's Ed25519 public key (for offline citation-receipt verification). Callers verify receipt signatures using WebCrypto with this key.
- find_practitioner: Recommend 3 Japanese licensed practitioner types (行政書士 / 税理士 / 中小企業診断士 / 社労士) for the grant's category. Returns role explanations and official-association registry links. **Informational only** — LocalGov.jp does NOT broker, refer, or accept commission for these recommendations.
