compare

compare_municipal_subsidies

Compare same-category subsidies across nearby municipalities (same prefecture by default). Useful for relocation / siting decisions. Free.

municipality

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.

practitioner

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.

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.

subsidies

search_subsidies

Search Japanese central + municipal subsidies. Combine keyword (Japanese), prefecture, municipality_code, category, or minimum amount. Returns up to `limit` records. Free.

subsidy

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.

supplementary

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.

verify

verify_receipt

Return LocalGov.jp's Ed25519 public key (for offline citation-receipt verification). Callers verify receipt signatures using WebCrypto with this key.

Localgov Jp — questions

Answers built from our own checks of this server.

What can Localgov Jp do?

It exposes 8 tools, read directly from the server on our last check. Among them: compare_municipal_subsidies, find_practitioner, find_supplementary_grants, get_municipality_grants, get_subsidy_detail, search_subsidies and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Localgov Jp working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 228 ms. The bar chart above shows every period we have measured.

How do I connect Localgov Jp?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Localgov Jp need an API key?

No. Localgov Jp completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Localgov Jp?

It answers our handshake in 228 ms on average, which is faster than 57% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Localgov Jp?

The npm package @localgov-jp/mcp-server was installed 30 times in the last week. Week over week that is +11%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Localgov Jp open source?

Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
