## 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 2026-10-23.

- **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**: 71/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 422 tokens (~211/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 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 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 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).

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-22 (score 74, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-10-21 (score 73, 0)

## MCP tools (2)

### `check_service_area` (~107 tokens)

Conferir área atendida

Diz se um município está na área atendida pela CSolar Energia para instalação de energia solar. A área atendida é o estado de São Paulo (645 municípios). Informe o município e, se souber, a UF. Não pede nem guarda dados pessoais.

Input parameters:

- `cidade` (string, required): Nome do município, por exemplo Sorocaba.
- `uf` (string): UF do município, opcional (ex.: SP). Ajuda quando há municípios com o mesmo nome em outros estados.

Output parameters:

- `area_atendida` (string)
- `fale_com_a_csolar` (string|null): Contato com a equipe; null quando é de fora da área.
- `mensagem` (string)
- `municipio` (string|null): Nome oficial do município, quando está na lista do site.
- `saiba_mais` (string|null): Página do município no site, quando está na área atendida.
- `situacao` (string)
- `uf` (string|null)

### `estimate_solar_system` (~238 tokens)

Estimar sistema de energia solar

Estima um sistema de energia solar com microinversores a partir do consumo mensal em kWh ou do valor mensal da conta de luz em reais. Devolve potência em kWp, número de módulos, geração mensal, economia mensal, preço instalado e tempo de retorno, pela tabela de preços da CSolar Energia (setembro/2026). O cálculo usa a irradiação da região de Sorocaba/SP; fora da área atendida (estado de São Paulo), os números são só referência. É estimativa, não orçamento. Não pede nem guarda dados pessoais.

Input parameters:

- `cidade` (string): Município da instalação, opcional. Não muda o cálculo; serve para dizer se fica na área atendida.
- `consumo_kwh_mes` (number): Consumo mensal de energia em kWh, como aparece na conta de luz. Aceito de 50 a 20.000 kWh.
- `uf` (string): UF do município, opcional (ex.: SP).
- `valor_conta_mes` (number): Valor mensal da conta de luz em reais. Use quando não souber o consumo em kWh.

Output parameters:

- `area`: Situação do município informado; null quando não veio cidade.
- `aviso` (string)
- `base_do_calculo` (string)
- `consumo_calculado_pela_conta` (boolean): true quando o consumo veio do valor da conta.
- `consumo_kwh_mes` (number): Consumo usado no cálculo, em kWh por mês.
- `economia_mensal_reais` (number)
- `fale_com_a_csolar` (string|null): Contato com a equipe; null quando o município é de fora da área.
- `geracao_mensal_kwh` (number)
- `modulos` (integer)
- `potencia_do_modulo_w` (integer)
- `potencia_kwp` (number)
- `preco_instalado_reais` (number): Preço do sistema instalado, pela tabela da CSolar.
- `retorno_anos` (number): Tempo aproximado para a economia pagar o sistema.
- `saiba_mais` (string): Página do site sobre preço de energia solar.
- `tabela_de_precos` (string)
- `tarifa_reais_por_kwh` (number): Tarifa usada para converter a conta em consumo.
