Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (6)

get_outlineread-onlyIndented 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_pageread-onlyReturns 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_subtreeread-onlyOutline 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_topicsread-onlyLists 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_libraryread-onlyFull-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_topicsread-onlySearches 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.
