## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### 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: 71 (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
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_health (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_series (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_series (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 624 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: 4, about 624 tokens to load them all
- tool set hash: 860d7592c679e48ae66f172fee3cd266
- badge: [![protogrid quality](https://protogrid.dev/badge/org.ai-lifeline/ai-lifeline.svg)](https://protogrid.dev/servers/org.ai-lifeline/ai-lifeline)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `get_health`: Return the liveness of AI Lifeline itself from /api/health.json: site_status (ok/degraded), totals (series, stale, fetch_failed,
    source_under_review, not_measured), the staleness rule as written, the generation time per edition, and per series: last confirmed
    observation date, update frequency, next expected update, stale flag, age_days and the status of the last fetch.
    region: optional filter 'jp'|'us'|'eu'|'sg'. only_stale: return only series with stale=true. Nothing here judges the observed world.
- `get_series`: Return one series by its permanent id ('<region>/<chapter>/<series_key>', e.g. 'jp/fiscal/jgb_yield') with the latest published
    value, unit, observed_at (observation date), value_status (final/provisional), the primary source (name, source_url, license,
    attribution), update frequency, last confirmed date, staleness judgement from health.json, limitations, page and API URLs, and checked_at
    (generation time of the site files). Values are the ones published by the site; nothing is recomputed.
- `list_series`: List the chapters AI Lifeline publishes (one entry per chapter page, from /api/index.json) with their page URL, API URL,
    the one-sentence answer line, the headline value (value, unit, date) and the series ids that belong to the chapter.
    region: optional filter, one of 'jp', 'us', 'eu', 'sg'. Returns exactly what index.json and series.json contain; no re-aggregation.
- `search_series`: Search published series by words in the series id, name, chapter, unit or source name (case-insensitive substring match over
    /api/series.json). Returns up to `limit` matches with series_id, name, unit, region, chapter, update_frequency, last_confirmed
    and source name; use get_series for the value. No ranking beyond match order in the registry.
