概览

AI 生成的概览

LienDeadline 根据建材供应商的交货事实计算美国初步通知与机械留置权截止日期,附法条来源,并提供各州留置权指南。

可以做什么
  • 查询任一美国州或华盛顿特区供应商截止日期范围的覆盖情况并收集所需事实
  • 依据已确认的交货与项目事实计算带来源的通知和留置权截止日期,包括需复核的结果
  • 运行佛罗里达和堪萨斯私人项目的旧版截止日期基线
  • 读取单个州的留置权指南,含规则、法条引用、截止日期表和常见问题
  • 列出全部已发布的 50 个州及华盛顿特区留置权指南
适用场景
当建材供应商需要了解某个具体工程的初步通知或留置权申报截止日期时使用,或需要带法条引用的某州机械留置权规则时使用。它是规划辅助工具,不代办申报,也不构成法律意见。
运行要求
远程 streamable HTTP 端点,或需 Node.js 22.22 及以上版本的本地 npm 包。公开州指南无需账户或密钥。供应商查询与计算需要客户 API 密钥:托管调用以 bearer 令牌发送,本地使用则设置 LIENDEADLINE_API_KEY。
安装前请注意
供应商事实(州、日期、项目类型、雇佣方、是/否/未知回答)会发送至 LienDeadline API 进行计算。完成的计算会消耗套餐额度。托管服务器记录请求元数据,并可能向 PostHog 发送匿名使用遥测。它不发送通知、不申报留置权、不付款,结果为教育性基线,须经律师核实。

README

[LienDeadline: mechanics lien and notice deadlines for AI assistants]

[Listed in Claude's Connectors directory] [Listed in the official MCP Registry] [npm version] [Glama score] [MIT license]

[LienDeadline MCP server]

Ask your AI assistant when your preliminary notice and mechanics lien deadlines fall, and get the statute behind every date. This MCP server connects Claude, ChatGPT, Cursor, VS Code and any other MCP client to LienDeadline, the deadline engine for US construction material suppliers. There is nothing to install: add one URL.

Why LienDeadline

Miss a preliminary notice or a lien filing deadline and a supplier can lose its lien rights on the job, and with them the leverage to get paid. The rules change with the state, the project type and who hired you. LienDeadline turns your delivery dates into those deadlines and shows its work.

  • Coverage for your exact project. Check any US state or DC, project type, and hiring relationship. For supported scopes, use the returned questions to confirm delivery dates and other facts that can affect notice and lien deadlines.
  • The statute behind every date. Each deadline cites its source, so your team and your counsel can check it.
  • Never a guessed date. Missing facts and unsupported project scopes come back as "needs review", with the reason.
  • Lien guides for all 50 states and DC. Rule summaries, deadline tables and common questions, with statute citations.
  • Safe by design. Supplier discovery and calculations require a caller customer key; completed calculations consume plan allowance. Public guides need no account or key. Nothing sends notices, files liens or makes payments.

Quick start

Connecting to the hosted server and using public guides needs no install, account or key:

https://mcp.liendeadline.com/mcp

The no-authentication connection settings below cover the transport and public guides. Supplier discovery and calculations require the caller's dedicated customer key through the client's approved credential settings. Discovery does not consume calculation allowance; completed calculations do.

ClientHow to add it

Any MCP clientStreamable HTTP at the URL above. Public guides need no authentication; supplier tools need a customer key.

Want your agent to ask the right questions too? The LienDeadline agent skill (GitHub) teaches it which facts to collect. The Claude Code plugin adds the skill and this server in one step:

bash
claude plugin marketplace add LienDeadline/skillsclaude plugin install liendeadline@liendeadline
Run it locally instead (npm, stdio)

The local server needs Node.js 22.22 or newer and serves every tool, including the two customer API tools. It ships npm-shrinkwrap.json, so npx installs the exact dependency versions each release was tested with.

Claude Desktop: download liendeadline-mcp-<version>.mcpb from the latest release and open it.

Claude Code:

bash
claude mcp add liendeadline -- npx -y liendeadline-mcp

What you can ask

[A Florida supplier asks for its deadlines; LienDeadline returns the Notice to Owner deadline, Sep 17, 2026, under Fla. Stat. § 713.06(2)(a), and the claim of lien deadline, Dec 9, 2026, under Fla. Stat. § 713.08(5)]

Try asking:

  • "What facts do you need to check supplier deadlines for a Maryland commercial project where the owner hired us directly?"
  • "We delivered to a Florida commercial job for a subcontractor from Aug 3 to Sep 10, 2026. No final payment, no termination. When are our notice and lien deadlines?"
  • "Same job, but I don't know whether the owner made final payment. What can you tell me?"
  • "Walk me through Texas mechanics lien rules for a material supplier and cite the statutes."
  • "Which states do you have lien guides for? Show me Georgia's."

Coverage

Supplier discovery and calculations (v3)Check any US state or DC with get_supplier_questions. Dates depend on the exact scope and confirmed facts.Customer key. Discovery uses no calculation allowance. Completed calculations consume allowance.
Delivery-event baselines (v2)Florida and Kansas private projectsCustomer key; completed calculations consume allowance

The website calculator and the v3 tools use the API's current reviewed rules. Start with discovery for the exact project. Supported private scopes can produce dates after the relevant facts are confirmed. Public projects and unsupported scopes require qualified review. Unresolved facts can also leave individual deadlines under review. An unavailable reviewed source returns an error.

How it works

  1. You ask your AI assistant about a job.
  2. The assistant checks coverage and asks which facts apply to the project.
  3. LienDeadline evaluates the confirmed facts against the discovered rules. Each calculated deadline includes its sources. Unresolved outcomes include the reason.
  4. Before showing a supplier deadline, the server checks that the result echoes exactly the facts you sent. A mismatch is reported as an error, never as a date.

Privacy and safety

  • Account usage. Supplier discovery and calculations require a customer key. Discovery uses no calculation allowance; completed calculations consume plan allowance. Hosted callers send their own Authorization: Bearer <key> on each request; local callers set LIENDEADLINE_API_KEY. The hosted server never uses a service-wide key. State guides remain public.
  • What's sent. The facts you give (state, dates, project type, who hired you and your yes, no or unknown answers) go to the LienDeadline API to calculate. Guide lookups send only a state code.
  • Hosted server. Its logs record the method, status and response time of each request, never your inputs. Google Cloud's own request log also records the URL, client IP address and user agent. The server may count usage anonymously in PostHog, including tool name, success, duration, client family and a goal from a fixed list. The telemetry excludes tool inputs, results and IP addresses.
  • Local server. It has no telemetry of its own.

Details: LienDeadline privacy policy.

Not legal advice

Results are educational baselines calculated from published state rules. Statutes change and every project is different, so verify critical deadlines with counsel before relying on them. LienDeadline is not a law firm and does not file anything on your behalf.

calculate_supplier_deadlines

Calculate legacy Florida or Kansas supplier deadlines

Legacy calculator for Florida and Kansas private projects. Calculates a material supplier's preliminary notice and lien filing deadlines from delivery events (contract supplier-events-v2), for questions that need deadline dates. Available baselines cover Florida and Kansas private projects; other states and public projects return review_required, which is a valid result, not an error. How the parameters depend on each other: last_delivery_date is required when deliveries_complete is true. Florida (FL) takes florida_final_payment_status and florida_termination_status; Kansas (KS) takes kansas_extension_status; these are rejected for other states. Each takes yes, no or unknown: an omitted or unknown answer keeps the affected deadline under review, and a blanket review flag is not accepted. The Florida final-payment answer holds the notice for suppliers not hired by the owner. A Florida event date is accepted only with the matching yes answer. Delivery dates are furnishing dates, not invoice dates. Returns JSON with an overall status (calculated or review_required), preliminary_notice and lien_filing (each with its own status: calculated, not_required, review_required or awaiting_final_delivery, plus deadline, days_from_now, description and statute source_url), critical_warnings, statute_citations, an exact echo of the submitted inputs and a disclaimer. Invalid or contradictory facts return an error naming the field before any API call. Requires a customer key and consumes one plan calculation unit. No project is saved, notice sent or lien filed. Not legal advice.

get_supplier_questions

Check supplier project coverage and questions

Start here for a material supplier deadline. Check live supplier-events-v3 coverage for any US state or DC, project type, and hiring relationship. Returns supported, review_required, or no_lien_right with a reason, applicable event questions, date policies, sources, and exact rule and question identities. It may also return recurring_notice_intake and short-form guidance. Confirm ordinary answers against the project facts. Requires a customer key. Discovery needs no delivery dates and uses no calculation allowance. A 503 means the reviewed source is unavailable.

calculate_supplier_deadlines_v3

Calculate supplier deadlines from confirmed project facts

Evaluates confirmed supplier-events-v3 facts against the rule and question identities from v3 discovery. Returns separate sourced notice and lien outcomes, including qualified review when relevant facts are unresolved, and an exact nested input echo. When RI discovery asks ri_mailed_within_200_days after ri_mailed=yes, confirm whether mailing occurred within 200 days of first delivery. No, Unknown or omitted confirmation requires review; recording alone does not establish a 40-day target. Only calculated outcomes contain calculated deadline dates. Report every candidate_deadlines entry with its ID, date and sources under the API explanation. For NH review fallbacks, first_furnishing is a conservative checkpoint and final_furnishing is informational pending contract grouping and qualifying completion; passing the first checkpoint does not itself establish expiry. A calculated contract_completion outcome uses only the returned deadline, without substituting the first checkpoint or recomputing a date. Review candidates do not establish filing deadlines, completion or scheduled reminders. An optional preliminary_notice.notice_duties collection contains independently required named notices, each with its own calculated date, explanation and sources; the legacy preliminary date is only their earliest summary. Report every validated duty without inferring duties from candidates or treating one notice as satisfying all duties. A separate optional preliminary_notice.planned_notice_targets collection contains qualified intent planning targets with their target dates, assumed filing dates, full ten- or thirty-day intervals, explanations and sources. Planning targets do not establish statutory expirations, actual filing, notice completion or scheduled notifications. An optional verified action_by is a Conservative action date planning target under qualified review; the statutory deadline and countdown remain unresolved, with explanation, sources and warnings. Optional recurring

get_state_lien_guide

Get the lien guide for one state

Returns LienDeadline's editorial mechanics lien and preliminary notice guide for one state or DC: rules (rule summary with statute citations), deadline_rows (deadline table), faqs (common questions) and source_url (the guide's web page), roughly 4 KB of JSON. For questions about how a state's lien or notice rules work, why a deadline falls where it does, or which statute applies. An unknown state code returns an error. The guide is an editorial reference, not a calculation: its day counts are summaries, not computed deadlines. Public and read-only; no key needed.
