## Trust

- hygiene: 100
- liveness: 99
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-99% +updated-19d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 91/100 (strong)

### 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`: 10 of 10 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,380 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: 10, about 1,380 tokens to load them all
- tool set hash: 0b945501b67e1b5a018044da6f8705aa
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.lbruce-wq/international-classifications.svg)](https://protogrid.dev/servers/io.github.lbruce-wq/international-classifications)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (10)

- `browse_hierarchy`: Browse top-level nodes or immediate children. Curated families return node_kind=codelist containers at root; pass that code as parent_code to browse its options.
- `export_choice_list`: Return a structured choice list at a selected hierarchy level. MICS exports require one codelist_id and never merge unrelated answer lists.
- `get_classification`: Get authoritative metadata and coverage for one classification_id returned by list_classifications.
- `get_code_definition`: Retrieve one exact code or codelist container, including its node_kind, hierarchy position and explanatory notes.
- `list_classifications`: List classification families, versions, custodians, coverage and licensing notes. Start here when the correct standard is unknown.
- `list_codelists`: List independent option lists within a classification before searching or exporting one list.
- `map_codes`: Apply official stored correspondences and expose splits, merges, changed meanings and unmapped codes. Never assume one-to-one equivalence.
- `recommend_classifications`: Return a deterministic ranked shortlist of all relevant classification concepts and codelists. Ranking supports user choice; it is not an automatic selection. Include answer options and context.
- `search_codes`: Full-text search labels and notes. Results restrict to one option list only when codelist_id is explicitly supplied.
- `validate_codes`: Validate exact codes against one named classification version.
