概览

AI 生成的概览

按美国财政部 OFAC 制裁名单筛查加密钱包地址及个人或公司名称，按次通过 x402 付费。

可以做什么: 按 OFAC 制裁名单核查加密钱包地址，覆盖比特币、以太坊/EVM、USDT、USDC、Tron、莱特币、门罗币和 Solana
按 OFAC SDN 与综合名单筛查个人、公司、船舶或航空器名称（含别名），返回无匹配、潜在匹配或强潜在匹配
查看已加载的 OFAC 名单、条目与钱包数量及最近刷新时间（免费）
适用场景: 适合在向陌生对手方付款、接纳客户或钱包、接收资金或与供应商签约之前，在助手工作流中快速做一次制裁筛查。
运行要求: 远程 Streamable HTTP 端点，无需账号或 API 密钥。付费工具按次以 USDC 经 x402 计费，客户端需支持 x402 支付，或使用在 Base 上持有 USDC 的钱包。免费的名单状态工具无需付费即可使用。

安装前请注意

付费调用按次收费（钱包核查 0.002 美元，名称筛查 0.003/0.005 美元），多次调用会累积费用。筛查结果仅供参考，不能替代正式的合规审查。README 的钱包配置要求提供私钥，应使用专用的低余额钱包而非主钱包。

安装

在 SourceWeft 中

打开控制台中的 Sanctions 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。

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.
