## Trust

- hygiene: 80
- liveness: 99
- freshness: 100
- provenance: 55
- drivers: +dns-namespace +website +reachable +uptime-98% +updated-14d-ago -no-repository
- 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`: 5 of 5 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 809 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: 5, about 809 tokens to load them all
- tool set hash: c8ac644b15735cc36eed09b7900222a4
- badge: [![protogrid quality](https://protogrid.dev/badge/co.frontierresearch/frontier.svg)](https://protogrid.dev/servers/co.frontierresearch/frontier)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (5)

- `explain_frontier_score`: The Frontier Score method: its three pillars and what each measures, recency, the integrity rule, tiers and confidence.
- `get_breakthrough`: Everything Frontier holds on one entry: the plain-language summary, why it matters and what to watch, authors and institutions, the full Frontier Score breakdown (each pillar and what drives it, recency and confidence) and the sources behind each figure. Accepts an OpenAlex work id (e.g. W7214802080), an entry slug, or a frontierresearch.co entry URL.
- `latest_breakthroughs`: What Frontier added most recently: the entries listed in the last N days (the index adds a few new papers from the top journals every day), newest first, optionally within one field.
- `list_fields`: The research fields Frontier covers, with how many entries each holds and its median Frontier Score.
- `search_breakthroughs`: Search Frontier's evidence-scored index of new research from the top scientific journals. Matches the query against titles, plain-language summaries, authors and topics, optionally within one field, and returns the matching entries ranked by Frontier Score (or newest paper first), each with its summary, score, Frontier URL and DOI. Leave the query empty to browse a field.
