## Trust

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

- drivers: +repository +namespace-matches-repo +website +reachable +uptime-100% +updated-2d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 89/100 (new)

### 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: 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`: 7 of 7 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,014 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

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

- n/a `stability.changes`, `stability.rug_pull`, `stability.new_links`: tool history recorded for 2 of the 7 days needed

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

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: deps.dev does not know @ortho-earth/mcp@0.1.0

- tools: 7, about 1,014 tokens to load them all
- tool set hash: 1956208f0566d13c521a3ca8f701ee84
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.kenjiyoshidahome2026-bit/ortho-earth.svg)](https://protogrid.dev/servers/io.github.kenjiyoshidahome2026-bit/ortho-earth)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (7)

- `check_compat`: Looks up how the official MapLibre GL JS examples and CesiumJS Sandcastle examples matching the query run on Ortho Earth (same picture / same answers / runs partly / does not run), with notes and links to side-by-side comparisons, and how MapLibre style properties are read (e.g. "fill-extrusion", "line-dasharray").
- `get_facts`: Latest version and release date, npm packages, licenses, and how many official MapLibre GL JS and CesiumJS examples run unchanged on Ortho Earth. Rebuilt on every deploy of www.ortho-earth.com. Call this before stating a version number or a compatibility figure.
- `get_started`: The step-by-step recipe for putting the Ortho Earth globe in a web page, with the exact file contents. Every step is run by an automated test against the published npm packages. route "vite" = npm + Vite project with @ortho-earth/globe (recommended); route "html" = a plain HTML page without a bundler.
- `list_apps`: The apps and demos on www.ortho-earth.com, each with its link and a one-line description. Useful for showing what the engine can do.
- `lookup_api`: Returns the TypeScript declaration (with its doc comment) of an Ortho Earth API from the published types: createGlobe and its options (globe.d.ts), the map object it returns (globe-map.ts), and the MapLibre-compatible facade (maplibre.d.ts). Doc comments are partly in Japanese.
- `search_docs`: Full-text search over the Ortho Earth documentation (the recipe, the changelog, migration guides from MapLibre GL JS, CesiumJS, Leaflet and Google Maps, the engine overview, GeoPBF, Gint, comparison articles). Returns the best matching sections with their source page.
- `view_link`: Makes a www.ortho-earth.com link that opens the 3D globe at a place, and the matching view string for createGlobe({ view }). zoom uses the same scale as the view string (about 0–2 for the whole Earth, 12 for a city). app "japan" adds Japan's detailed basemap and PLATEAU 3D buildings.
