## 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`: 6 of 6 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,104 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: 6, about 1,104 tokens to load them all
- tool set hash: f82ab2f2f4606f682f5d8cbbe02e4f2b
- badge: [![protogrid quality](https://protogrid.dev/badge/com.cyberlibrary/library.svg)](https://protogrid.dev/servers/com.cyberlibrary/library)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `get_outline`: Indented outline of the library tree below a path (default: whole library) down to a given depth. Useful to understand how a domain is organized before reading pages. Capped at 400 entries. Docs: https://www.cyberlibrary.com/en/mcp
- `get_page`: Returns a page of the Cyber Library as markdown with its metadata (title, URL, breadcrumbs, last update, contributors) and, for folders, the list of child pages. Paths look like "offensive/software/applications/server/containers/container-escape"; full URLs are accepted. Docs: https://www.cyberlibrary.com/en/mcp
- `get_planned_subtree`: Outline of the planned taxonomy below a topic id (from search_planned_topics; omit for the Cyber root) with each topic's kind and status. Capped at 400 entries. Docs: https://www.cyberlibrary.com/en/mcp
- `list_topics`: Lists the direct children of a folder of the library (or the six top-level sections when no path is given): title, path, number of sub-pages and description. Docs: https://www.cyberlibrary.com/en/mcp
- `search_library`: Full-text search over the published pages of cyberlibrary.com (titles, descriptions, paths). Returns the best matches with their path and URL; pass a path to get_page to read it. Docs: https://www.cyberlibrary.com/en/mcp
- `search_planned_topics`: Searches the structure database snapshot of the Cyber taxonomy: every planned topic (8k+), including drafts not yet published on the site, with its status (draft, review, ready, generated, published) and position. Use get_planned_subtree with an id to explore around a match. Docs: https://www.cyberlibrary.com/en/mcp
