England Works Watch — UK sponsor compliance/change intelligence MCP: https://works.regevidencehub.com/mcp Scope: Skilled Worker sponsor duties only. Free MCP tools: england_works_watch_info, licensing_source_status, list_supported_change_events. Paid: assess_change_impact $0.02; batch_assess_changes $0.05. Use when an employer/HR/HRIS Agent needs deterministic evidence-backed sponsor change impact. Free vs paid: free tools provide scope, source status and supported-event vocabulary; paid tools return a deterministic decision with evidence-linked rationale, required action/deadline fields, and explicit review or missing-input state. Example paid result (synthetic shape only): unauthorised_absence, Skilled Worker, 11 consecutive working days -> a response containing status, decision_code, rationale, required_actions, deadline, missing_inputs, review_reasons, affected_rules and disclaimer. Payment guidance: x402 PaymentRequired -> sign buyer-side Base mainnet USDC (eip155:8453) -> retry the same paid tool with payment metadata. If payment or settlement is not verified, the paid decision is not executed. Decision arguments use a top-level payload object containing structured change facts. Official GOV.UK evidence is fingerprinted continuously; changed/stale evidence fails closed. Never treat REVIEW_REQUIRED or INSUFFICIENT_INPUT as clearance. Not legal advice.
