Anlyon alternative

4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Busca livros da Editora Blucher por tema, título, autor ou pergunta em linguagem natural; filtra por área, formato, idioma e disponibilidade. Use sempre que a pessoa quiser saber se a Blucher tem livro sobre um assunto, procurar um título ou autor (tolera erro de digitação) ou montar uma lista de leitura. Por padrão devolve a edição vigente do que está à venda e também os livros fora de catálogo, marcados; de uma obra com edição mais recente, vem a mais recente (e a antiga, com edicao.substituido_por, quando a busca casou com o título dela); um ISBN como consulta devolve o livro desse ISBN (mesmo antigo ou fora de catálogo). Para a ficha completa (preço detalhado, sumário, edições, link de compra), chame obter_livro com o ISBN. Search the catalog of Editora Blucher (Brazilian technical, scientific and academic publisher) by topic, title, author or natural-language question; filter by area, format, language and availability. Use it whenever the user asks whether Blucher has a book on a subject, looks for a title or author (typos tolerated) or builds a reading list. By default returns the current edition of books on sale plus out-of-catalog books, flagged; for a work with a newer edition you get the newer one (and the old one, with edicao.substituido_por, when the query matched its title); an ISBN as the query returns that book. Call obter_livro with the ISBN for the full record.

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.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged untrusted-input or outbound.

Reads private data1
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json

  "permissions": {
    "allow": [
      "mcp__catalogo__search",

}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as catalogo. Review it before you use it.
