概览

AI 生成的概览

远程 MCP 服务器，针对美国地址或坐标一次调用即可返回自然灾害风险报告，含 FEMA 洪水区与各类灾害评级。

可以做什么: 查询美国房产的整体自然灾害风险及其主要成因
获取 FEMA 洪水区、是否需要洪水保险以及地震风险
查看野火、飓风、龙卷风、高温、洪水、地震等多项灾害评级
了解所在县的灾害历史，以及所属县和人口普查区
适用场景: 在评估、挂牌、投保或研究美国房产时，希望一次调用就拿到灾害与洪水区信息，而不必从多个政府来源自行拼凑。
运行要求: 需要远程 Streamable HTTP 端点；未声明账号或 API 密钥。README 说明付费工具按次以 USDC 通过 x402 计费（每次几美分），本地封装版需要钱包私钥和单次调用价格上限。

安装前请注意

付费调用会实际花费 USDC；README 建议使用只存少量资金的专用钱包而非主钱包，封装版会要求钱包私钥。结果仅限美国、仅供参考，不构成法律或保险建议。

安装

在 SourceWeft 中

打开控制台中的 Property Risk Check，将其添加到工作区。
为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

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.
