## Quality 79/100 (good)

### 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: 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: list_categories (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_atomno_servers (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_servers (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 317 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: 4, about 317 tokens to load them all
- tool set hash: af40a64d37a60ee328691da278e7c992
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.atomno-mcp/mcp-catalog.svg)](https://protogrid.dev/servers/io.github.atomno-mcp/mcp-catalog)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `get_server`: Карточка одного сервера из каталога: описание, ссылка на страницу, репозиторий, пакет. Идентификатор — короткий slug, адрес /servers/автор/название, имя или имя пакета. Если карточки нет — found=false.
- `list_atomno_servers`: Публичные MCP-серверы семьи Atomno из этого каталога (ЕГРЮЛ, ФНС, ФССП, курсы ЦБ и др.). Только то, что уже есть на сайте.
- `list_categories`: Список категорий каталога и сколько в каждой серверов. Только публичные данные сайта.
- `search_servers`: Найти MCP-сервер в каталоге mcp-catalog.ru по формулировке задачи (например: «ЕГРЮЛ», «postgres», «курсы ЦБ»). Возвращает только реальные совпадения. Если ничего не нашлось — found=false, без подмены похожими.
