概覽

AI 產生的概覽

遠端 MCP 伺服器，針對美國地址或座標一次呼叫即可回傳自然災害風險報告，含 FEMA 洪水區與各類災害評級。

可以做什麼: 查詢美國房產的整體自然災害風險及其主要成因
取得 FEMA 洪水區、是否需要洪水保險以及地震風險
查看野火、颶風、龍捲風、高溫、洪水、地震等多項災害評級
了解所在郡的災害歷史，以及所屬郡和人口普查區
適用情境: 在評估、刊登、投保或研究美國房產時，希望一次呼叫就取得災害與洪水區資訊，而不必從多個政府來源自行拼湊。
執行需求: 需要遠端 Streamable HTTP 端點；未宣告帳號或 API 金鑰。README 說明付費工具按次以 USDC 透過 x402 計費（每次幾美分），本機封裝版需要錢包私鑰與單次呼叫價格上限。

安裝前請注意

付費呼叫會實際花費 USDC；README 建議使用只存少量資金的專用錢包而非主錢包，封裝版會要求錢包私鑰。結果僅限美國、僅供參考，不構成法律或保險建議。

README

Public Domain Check: MCP server

Is this book, film, song or artwork in the US public domain, and when does it enter it? This MCP server answers that question for AI agents. It's backed by:

2.38 million US Copyright Office registrations (1923–1977)
434,000 renewal records, linked to their registrations
the US copyright term rules

Paid tools cost a few cents per call, paid in USDC through x402. There's no account or API key.

Remote MCP (Streamable HTTP): https://public-domain-check-production.up.railway.app/mcp
HTTP API and docs: https://public-domain-check-production.up.railway.app (llms.txt, OpenAPI)

Tools

Tool	Price	What it does
`check_public_domain`	$0.01 (brief) / $0.02 (full)	Returns the status (public domain, likely public domain, in copyright, or undetermined), the public-domain date, the confidence, a one-line reason and the record IDs. Full mode adds the complete reasoning and records. Includes HathiTrust's reviewer verdict when one exists; pass `countries` for the UK, EU, Canada, Australia, Japan, China or India. For 1923–1977 books, a title is enough.
`check_public_domain_batch`	$0.0075 per work (brief) / $0.015 (full)	Checks up to 50 works per call. Local wrapper only.
`search_copyright_renewals`	$0.01	Shows who renewed a work's copyright and when, which usually points to the rightsholder.
`copyright_rules_for_year`	free	Tells you which rule applies to a publication year, and whether a record lookup is needed.
`public_domain_day`	free	Lists what enters the US public domain on January 1.
`check_wallet_sanctions`	$0.002	Checks whether a crypto wallet is on the US Treasury (OFAC) sanctions lists (Bitcoin, Ethereum/EVM, USDT, USDC, Tron and more). Use it before paying an unknown wallet.
`screen_sanctions_name`	$0.003 / $0.005	Screens a person, company, vessel or aircraft name against the OFAC SDN and Consolidated lists, including aliases and spelling variants.
`check_property_risk`	$0.02 / $0.04	One-call natural hazard report for a US address: overall risk and what drives it, FEMA flood zone and insurance requirement, seismic risk, ratings for 18 hazards from FEMA's National Risk Index, and federal disaster declarations in the county since 2000.

You're never charged when a request is invalid or the service needs more information.

Brief answers by default. check_public_domain returns a short answer: the status, the date, the confidence, a one-line reason, and the record IDs. That's about 80% fewer tokens for your agent to read. For the complete reasoning and records ($0.02), pass format: "full" (local wrapper) or call check_public_domain_full (remote MCP).

Use it

Claude Desktop, Cursor, Windsurf, and other MCP clients

Add this to your MCP config:

json

{  "mcpServers": {    "public-domain-check": {      "command": "npx",      "args": ["-y", "public-domain-check-mcp"],      "env": {        "WALLET_PRIVATE_KEY": "0x...",        "MAX_PRICE_PER_CALL": "0.25"      }    }  }}

{  "mcpServers": {    "public-domain-check": {      "command": "npx",      "args": ["-y", "public-domain-check-mcp"],      "env": {        "WALLET_PRIVATE_KEY": "0x...",        "MAX_PRICE_PER_CALL": "0.25"      }    }  }}

WALLET_PRIVATE_KEY is the private key of a wallet that holds a little USDC on Base. Use a dedicated wallet with a few dollars in it, not your main wallet.
Without a key, the free tools still work.
MAX_PRICE_PER_CALL is a hard cap, in US dollars, enforced on your machine. The wrapper refuses any call that costs more.

Agents with built-in x402 support

These include @x402/mcp, Coinbase AgentKit, and other x402-aware frameworks. Connect to the remote URL above. Paid tools return an x402 payment request, and your client pays it and retries.
