io.github.ChanghuLiu/england-works-watch is a remote MCP server published at england-works-watch-production.up.railway.app. It has been probed 15 times since 9/12/2026. It answered in 15 of them (100.0%), a near-uninterrupted record. Median response time is 213 ms, placing it among the faster endpoints. It offers a narrow, focused set of 5 tools. On the protocol side it speaks the 2026-07-28 stateless spec.

Tools the server advertised in the latest measurement — measured, not catalog-claimed.
england_works_watch_infoFree product information. Use for service scope, what England Works Watch does, pricing, cost, x402 network, payment, MCP endpoint, discovery metadata, or legal-advice disclaimer. Not for source freshness, supported-event lists, or change decisions. See the Example paid result and x402 payment guidance for the paid boundary.
licensing_source_statusFree GOV.UK evidence source status. Use for current guidance, source freshness, stale sources, changed fingerprints, blocking sources, review status, evidence lifecycle, or source coverage. Not for a specific sponsor change decision.
list_supported_change_eventsFree supported-event list. Use for capability questions such as 'Does this support salary, role and work location changes?' or when asking which sponsor events the tool can handle, which change types/categories are supported, or to list supported events: absence, salary, role or occupation code, work location or home working, delayed start, stopping sponsorship or worker departure, organisation change, TUPE, merger, takeover, or Home Office/UKVI sponsor reporting. Capability/list only; not impact, reporting, or required-action decisions.
assess_change_impactPaid single-event change decision. Use for one concrete Skilled Worker sponsor event to determine impact, including questions such as 'Does moving one sponsored worker to permanent home working trigger reporting?', whether Home Office/UKVI sponsor reporting is triggered, whether it is AFFECTED/NOT_AFFECTED, what the sponsor must do, or required actions. Handles one absence, salary, role or occupation-code, remote/home/work-location, delayed-start, stop-sponsoring/worker-departure, organisation, TUPE, merger, or takeover event. Returns an evidence-linked rationale, required action/deadline fields, and explicit review or missing-input state. Payment: x402 Base mainnet USDC; sign buyer-side and retry this same tool with payment metadata. Not multiple events.
payloadobjectrequiredbatch_assess_changesPaid batch/multiple-event change decision for 1-25 events. Use for a list, batch, set, several, many, multiple, 5, 8, 20 or other collection of sponsor changes; evaluate them together and return per-event results plus outcome counts. Payment: x402 Base mainnet USDC; sign buyer-side and retry this same tool with payment metadata. Not for one event.
payloadobjectrequiredDerived by comparing consecutive probes — changes in era, protocol version, build and reachability.

Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
The two probe legs separately: modern server/discover and legacy initialize.
