## Trust

- hygiene: 100
- liveness: 99
- freshness: 85
- provenance: 90
- drivers: +repository +namespace-matches-repo +website +reachable +uptime-96% ~updated-30d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 96/100 (strong)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 6 of 6 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,866 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 1,866 tokens to load them all
- tool set hash: 0fda3c4beb8bcc80b224756090be6eac
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.ChanghuLiu/england-works-watch.svg)](https://protogrid.dev/servers/io.github.ChanghuLiu/england-works-watch)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `assess_change_impact`: Check whether a specific employee/company change affects UK Skilled Worker sponsor duties. Use for salary, role, work-location, absence, delayed-start, stop-sponsoring, organisation, TUPE, merger or takeover changes. Use only facts explicitly supplied by the user; never infer or default missing compliance facts such as same_salary_option_still_met. Pass omissions through so the deterministic engine can return INSUFFICIENT_INPUT. Returns an evidence-linked decision and required next action.
- `batch_assess_changes`: Paid 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.
- `england_works_watch_info`: Free 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_status`: Check freshness and review status of the official GOV.UK evidence used by the sponsor-change checker.
- `list_supported_change_events`: List sponsor-change event types this checker can assess for Skilled Worker sponsor duties.
- `sponsor_change_checker_info`: Explain the UK Skilled Worker sponsor-change checker scope and supported decision states.
