    Why it is in this group

    • The name "cyanheads_describe_entry" says "describe": a word for reading.
    Description, as the server wrote it
    Return the description and install snippets for a named tool or server. For tools: the description, owning server, and connection metadata. For either kind: local (stdio, via npx) install snippets for every published server, plus remote (HTTP) connection snippets when a hosted endpoint exists — for every supported client, or one client via the client parameter.

    Why it is in this group

    • The name "cyanheads_search_catalog" says "search": a word for reading.
    Description, as the server wrote it
    Search fleet tools and servers by natural-language description. Returns ranked matches with brief summaries and the server each tool belongs to. Use scope "servers" to find which server handles a workflow; use the default scope "tools" to find specific tools.

    Annotations the server declares

    • readOnlyHint: true
    • openWorldHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
