Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 677 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name rolling-edition.

  • Pass
    Lists tools

    tools/list returned 7 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 677 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 677 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    0 of 15 parameters have a description (0%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Fail
    Website matches publisher

    The website host does not match the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-11-06T18:50:56.021686Z, within 180 days.

  • Not measured

Capabilities

Tools 7

check_code

Check an edition code, the 8 characters printed on a copy of a Rolling Edition book (such as 483B-Z9SS): "current", "out_of_date" with the current edition and what changed since, or "not_found". A match says which edition the code names; it doesn't prove a copy is authentic.

Discovered
get_changes

What changed in a book's editions, newest first: each edition's date, the kinds of change, its summaries, and the sections and examples it changed. Give `since_edition` for the editions after one you know, such as the edition a reader's copy names.

Discovered
get_contents

A book's chapters and sections, in reading order, each with the ID that get_section takes. `book` is the book's slug from list_books, such as "open-table-formats".

Discovered
get_section

Read one section of a book as Markdown, with its subsections, its code examples (each with the versions it was run on and whether it passes) and its citation block. A chapter's ID gives the chapter's opening. A long section comes in pages: pass the `next_cursor` you were given as `cursor` for the next one. An earlier ID of a section still works, and the answer says what it's called now.

Discovered
get_skill

A book's agent skill: its SKILL.md, in the Agent Skills format, with the methods the book teaches as procedures, each step linked to the section it comes from, and how to install the whole skill, with the chapters and examples, in Claude Code or any agent that reads the format. Read a step's section with get_section before acting on it. A book without one says so.

Discovered
list_books

List Rolling Edition's books: each one's slug, title, summary, level, areas and skills, its current edition, the date its examples last passed, how many of its examples pass, and its link. Give `topic`, an area or skill ID such as "data-engineering" or "large-language-models", to list only the books on it.

Discovered
search_books

Find the passages that best match `query`, by its words, across every book or within one (`book`, a slug). Each result has its book, edition, section ID and title, a snippet, and the citation block to cite it with. Read a whole result with get_section. `limit` is 5 unless you ask for up to 10.
