## 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 1,021 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`: 5 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 1,021 tokens to load them all
- tool set hash: a0e2151fbbf89f6eb23b1c5fbfe98a05
- tools last changed: 2026-10-15T12:43:04.444Z
- badge: [![protogrid quality](https://protogrid.dev/badge/by.ai-belarus/registry.svg)](https://protogrid.dev/servers/by.ai-belarus/registry)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-15 `entity_timeline` added
  - Change timeline of a Belarusian entity by UNP from collected data: an ordered log of canon changes per predicate (created / reaffirmed / superseded / conflict_detected), each event carrying old and new value, source registry and time (effective_at, observed_at). Lets an agent read anomalies over time (sudden address/head/activity change). Instant, no registry call. Хронология изменений субъекта по УНП из собранного.
- 2026-10-15 `sources_and_coverage` added
  - Machine-readable trust card of the registry itself: every source with provenance (organ, tier, URL) and its DECLARED access/rights (machine_api_authorization, terms_status) AS DECLARED in config — not asserted by this tool; plus coverage (claims and evidence per source, which sources give canon) and grounding invariants (total claims, how many lack evidence, off-source, freshness). Technical availability is NOT a legal right to use or redistribute the data. Карточка доверия: источники, права как задекларированы, покрытие и заземление.
- 2026-10-15 `check_counterparty` changed (description, inputSchema, outputSchema)
  - before: Live answer of the Belarusian State Register of Payers (MNS) and related registries right now: exists / active (да | нет | не_установлено), address, registration date, tax office, bankruptcy cases, exclusion from public procurement, KGK inspection plans, procurement history. Pass `name` from your documents to get a name-match verdict. Takes seconds; rate-limited. Живой ответ реестра по УНП.

- 2026-10-15 `search_companies` changed (description, inputSchema, outputSchema)
  - before: Search collected Belarusian legal entities by name fragment or UNP. Only legal entities are found by name (sole proprietors never are). Absence here is not absence in the state registry. Поиск юрлица по названию или УНП среди собранного.

- 2026-10-15 `lookup_company` changed (description, inputSchema, outputSchema)
  - before: Collected public card of a Belarusian business entity by UNP (9 digits): legal name, status, each statement with registry source, retrieval time and sha256 of the raw response; withheld fields with reasons. Instant, no registry call. Карточка субъекта по УНП из собранного.
