## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 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: search_supplements (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_guides (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_guide (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 633 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`: 3 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 633 tokens to load them all
- tool set hash: 13a18f4995f1a89abcf54a12ebd857bb
- tools last changed: 2026-10-13T05:47:57.361Z
- badge: [![protogrid quality](https://protogrid.dev/badge/science.supp/suppscience.svg)](https://protogrid.dev/servers/science.supp/suppscience)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-13 `get_training` added
  - Get one training topic by slug: overall and per-claim grades, how to apply it (sets, reps, rest), technique for exercises, who should be careful, FAQ, PubMed references, the supplements from this catalog that help with its goals, and the citable pageUrl (translations under "pt", "es", "de", "fr").
- 2026-10-13 `search_training` added
  - Search the evidence-graded training topics: training variables (sets, reps, rest, failure), methods (drop sets, HIIT, zone 2), exercises (squat, bench press…), weight-loss strategies and gym myths. Returns slug, type, grade and summary. Use get_training for the full page.
- 2026-09-30 `get_supplement` changed (description)
  - before: Get the full evidence analysis for one supplement by slug: per-claim evidence grades, studied dose, safety, PubMed references, purchase link (buyUrl), and the citable pageUrl (with a Portuguese version under "pt").
  - after: Get the full evidence analysis for one supplement by slug: per-claim evidence grades, studied dose, safety, interactions, FAQ, PubMed references, purchase link (buyUrl), and the citable pageUrl (translated fields under "pt", "es", "de", "fr").
