## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-06.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 63/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2114 tokens (~352/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 37/100
  - Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

### `buscar_livros` (~740 tokens)

Buscar livros da Blucher

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). Cada livro traz `url`, o link da página dele em www.blucher.com.br; a ficha completa (preço detalhado, sumário, edições) vem de obter_livro, pelo 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. Each book carries `url`, the link to its page on www.blucher.com.br; the full record comes from obter_livro, by ISBN.

## Common questions

### What is the Catálogo Blucher MCP server?

Catálogo Blucher is an MCP server listed in the public MCP registry as br.com.blucher/catalogo. Livros da Editora Blucher: busca, edição, preço, ementa / Blucher books: search, prices, syllabi. This page covers its hosted endpoint (https://catalogo.blucher.com.br/mcp).

### Is the Catálogo Blucher MCP server safe to use?

Catálogo Blucher scores 78 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Catálogo Blucher MCP server expose?

Catálogo Blucher exposes 6 tools: buscar_livros, obter_livro, recomendar_para_ementa, catalogo_facetas, search, fetch. Their descriptions and schemas cost roughly 1,535 tokens of context every time the server is loaded.

### Does the Catálogo Blucher MCP server require authentication?

No. We connected to Catálogo Blucher without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Catálogo Blucher MCP server still maintained?

Catálogo Blucher is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the Catálogo Blucher MCP server?

VerifyMCP ran 13 checks on Catálogo Blucher, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
