## 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 2026-11-04.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 61/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 687 tokens (~229/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 40/100
  - Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 92/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 75% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (3)

### `buscar_promocoes` (~262 tokens)

Buscar promoções na Shopee

Lista produtos da Shopee Brasil com queda de preço real, detectada pelo nosso histórico nos últimos 30 dias e que ainda vale (o 'de' do vendedor não conta). Cada produto traz discount.certainty: 'verified' significa que a queda está provada pela mediana ponderada pelo tempo das nossas leituras e PODE ser apresentada como economia; 'none' significa que não há desconto que se possa afirmar. O preço 'de' que o vendedor escreve no anúncio não sustenta desconto nenhum aqui. Citar o percentual sem o certainty ao lado desinforma o leitor.

Input parameters:

- `apenas_verificados` (boolean): Mantido por compatibilidade: desde 2026-10-14 esta ferramenta só devolve produtos cuja queda o nosso histórico comprova.
- `busca` (string): Texto procurado no título, só entre as quedas mais destacadas lidas (até 100); não é busca no catálogo inteiro.
- `categoria` (string): Slug da categoria. Omita para buscar em todas.
- `desconto_minimo` (integer): Queda real mínima, em porcentagem, contra o preço típico que medimos.
- `limite` (integer)
- `preco_maximo` (number): Preço máximo em reais.

### `historico_de_preco` (~97 tokens)

Histórico de preço de um produto

Série de preços observada para um produto da Shopee. Aceita o itemId ou a URL do produto. Devolve também o número de leituras: com menos de três não há base para afirmar queda, e a resposta diz isso explicitamente.

Input parameters:

- `produto` (string, required): itemId numérico da Shopee, ou a URL completa (https://shopee.com.br/product/<shopId>/<itemId>).

### `quedas_de_preco` (~165 tokens)

Quedas de preço detectadas

Produtos cujo preço caiu pelo menos 10% contra o valor TÍPICO dos últimos 30 dias (mediana ponderada pelo tempo que cada preço vigorou — promoção-relâmpago pesa só as horas que durou), ou que atingiram o menor preço já registrado. Exige 7 dias de acompanhamento. Cada produto traz discount.certainty: 'verified' significa que a queda está provada pela mediana ponderada pelo tempo das nossas leituras e PODE ser apresentada como economia; 'none' significa que não há desconto que se possa afirmar. O preço 'de' que o vendedor escreve no anúncio não sustenta desconto nenhum aqui. Citar o percentual sem o certainty ao lado desinforma o leitor.

Input parameters:

- `limite` (integer)
