概覽

AI 產生的概覽

遠端 MCP 伺服器，讓助理針對英國 Skilled Worker 擔保人變更是否影響擔保義務，給出附官方證據的預判結論。

可以做什麼
  • 說明檢查器的適用範圍、支援的判定狀態與變更事件類型
  • 查詢檢查器所用 GOV.UK 官方證據的新鮮度與複核狀態
  • 評估單一員工或公司變更是否影響 Skilled Worker 擔保義務，回傳四種判定之一，並附規則包版本、理由、官方證據與後續動作
  • 一次批次評估最多 25 個變更事件（README 列出，工具清單中未列出）
適用情境
適用於人資、人事營運、薪資或法遵流程，需要快速取得有來源依據的判斷：薪資、職務、工作地點、缺勤、TUPE 移轉或併購等變更是否觸發英國擔保義務。它是雇主端工具的預檢輔助，不提供個人簽證諮詢。
執行需求
需要遠端 Streamable HTTP 端點；未宣告本機套件、帳號或 API 金鑰。免費工具無需額外設定。付費判定工具需透過 Base 主網 USDC 的 x402 付款，付款由 EWW_PAYMENT_ENFORCED 設定控制，啟用時必須提供 EWW_X402_PAY_TO。
安裝前請注意
判定工具按次收費（單次 0.02 美元、批次 0.05 美元），且僅在付款驗證後才執行；另有 49 英鎊／30 天的擔保證據檢查點單獨販售。切勿傳送私鑰或助記詞，也不要把 REVIEW_REQUIRED 或 INSUFFICIENT_INPUT 當成合規放行。輸出不構成法律意見或內政部決定。

安裝

README

England Works Watch

UK sponsor compliance/change intelligence for AI agents and employer workflows.

This product converts current UK Home Office sponsor guidance into deterministic, evidence-linked change-impact decisions for Skilled Worker sponsors. It is designed for employer HR/People Ops agents, HRIS/payroll/recruitment workflows, sponsor-compliance tooling, and regulated adviser tooling. It is not an individual visa-advice chatbot.

Free entry and customer checkpoint

  • Product page: RegEvidenceHub England Works Watch.
  • Free MCP entry: service information, official-source status, and supported change-event discovery.
  • Customer checkpoint: create a sponsor evidence checkpoint for £49 / 30 days. The period allows re-checks of the same evidence; there is no auto-renewal or alert subscription.
  • Commercial MCP decisions use separate x402 charges; see x402.

Decision contract

Every supported change returns exactly one of:

  • AFFECTED
  • NOT_AFFECTED
  • REVIEW_REQUIRED
  • INSUFFICIENT_INPUT

Every substantive decision includes rule-pack version, effective date, rationale, official GOV.UK evidence, source version, source locator, and required next action where applicable. Missing critical facts, unsupported routes, contradictory inputs, or non-current source evidence fail closed.

V0.1 scope

Supported events: worker start delay; unauthorised absence; unpaid/reduced-pay absence; salary change; role/occupation change; normal work-location change; stopping sponsorship; sponsor organisation changes; TUPE transfer; merger/takeover.

Route scope is deliberately limited to Skilled Worker + sponsor duties.

Validation gate

  • 10 independent change-impact cases
  • 6 negative controls
  • 5 sponsor-event cases
  • 4 explicit fail-closed cases
  • 25 / 25 current fixture decisions passing

MCP tools

Free: england_works_watch_info, licensing_source_status, list_supported_change_events.

Decision: assess_change_impact, batch_assess_changes (up to 25 events).

Production transport is stateless Streamable HTTP at /mcp.

x402

Base mainnet eip155:8453, USDC, exact scheme, PayAI facilitator. assess_change_impact is $0.02; batch_assess_changes is $0.05. Payment is controlled by EWW_PAYMENT_ENFORCED; when enabled EWW_X402_PAY_TO is mandatory.

The free tools provide scope, supported-event vocabulary and official-source status. Paid tools add a deterministic change decision, evidence-linked rationale, required action/deadline fields, and explicit REVIEW_REQUIRED or INSUFFICIENT_INPUT states. At the x402 boundary, call the paid tool to receive PaymentRequired, sign the accepted Base-USDC authorization buyer-side, then retry the same tool call with payment metadata. The decision is not executed until payment is verified. The public england_works_watch_info tool includes a synthetic example result shape. Never send private keys or seed phrases.

Public discovery

/health, /mcp, /openapi.json, /llms.txt, /.well-known/x402, /.well-known/mcp/server-card.json, /analytics/summary.

Architecture

Agent structured facts -> MCP/x402 boundary -> source lifecycle gate -> deterministic rule engine -> evidence-linked result -> privacy-minimal analytics

There is no server-side LLM in the decision path.

Safety

Evidence-first sponsor compliance preflight only. Not legal advice, a Home Office decision, or a guarantee of compliance. REVIEW_REQUIRED and INSUFFICIENT_INPUT must never be presented downstream as clearance.
