## Trust

- hygiene: 100
- liveness: 99
- freshness: 100

- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 84/100 (good)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### 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`: 4 of 4 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,407 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 7 tool changes in 30 days
- fail `stability.rug_pull`: 1 tools kept their name but changed most of their description in 30 days; review before trusting them

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

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

- tools: 4, about 1,407 tokens to load them all
- tool set hash: 164b256ef2acbdc09ba969888c9d60a5
- tools last changed: 2026-10-09T21:18:10.635Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.rewindmap/rewindmap.svg)](https://protogrid.dev/servers/com.rewindmap/rewindmap)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-09 `create_video_link` changed (annotations)
- 2026-10-09 `search_events` changed (inputSchema, annotations)
- 2026-10-09 `find_polity` changed (inputSchema, annotations)
- 2026-10-09 `world_at_year` changed (inputSchema, annotations)
- 2026-10-02 `create_video_link` added
  - Build a link that opens RewindMap's short-video maker preloaded with a map clip: borders (and optional event layers) changing from one year to another over a place, with an optional title and map labels. The visitor opens the link and taps Download to get a watermarked MP4 (vertical 9:16 for Shorts/Reels/TikTok, or landscape). Rendering happens in the visitor's browser; this tool returns the link only, never a video file.
- 2026-09-27 `search_events` changed (description, inputSchema)
  - before: Search dated map events: battles (Wikidata), UCDP armed-conflict events since 1989, volcanic eruptions VEI 4+ (Smithsonian GVP), significant earthquakes (NOAA), witnessed meteorite falls, and UNESCO World Heritage sites (undated). Results are sorted by year.
  - after: Search map events: battles (Wikidata), UCDP armed-conflict events since 1989, volcanic eruptions VEI 4+ (Smithsonian GVP), significant earthquakes (NOAA), witnessed meteorite falls, and UNESCO World Heritage sites (undated). Month/day bounds match only events recorded at least that precisely; undated heritage sites match only searches without a date bound. Results are sorted by date.
- 2026-09-27 `world_at_year` changed (description) **meaning changed**
  - before: List the states, empires and cultures whose borders are on the map in a given year (OpenHistoricalMap data), optionally only those overlapping a region.
  - after: List states, empires and cultures with an OpenHistoricalMap border snapshot in a given year, optionally overlapping a region. Coverage is incomplete; an empty result does not establish historical absence.

Rendering happens in the visitor's browser; this tool returns the link only, never a video file.
- `find_polity`: Look up a state or empire by name or any of its Wikidata labels and aliases (substring, case-insensitive), or by Wikidata QID. Returns its lifespan, every border snapshot with its bounding box, and links.
- `search_events`: Search map events: battles (Wikidata), UCDP armed-conflict events since 1989, volcanic eruptions VEI 4+ (Smithsonian GVP), significant earthquakes (NOAA), witnessed meteorite falls, and UNESCO World Heritage sites (undated). Month/day bounds match only events recorded at least that precisely; undated heritage sites match only searches without a date bound. Results are sorted by date.
