## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `compute`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Calcula el resultado de una calculadora en vivo. Pasá el slug y un objeto inputs con los campos (ver get_calculator). Opcional lang (es|en|pt). Devuelve el resultado calculado en JSON.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `get_calculator`

- The name "get_calculator" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Devuelve la ficha de una calculadora por slug: qué inputs toma (id, tipo, requerido, valores válidos) y una URL de ejemplo. Usalo antes de compute para saber qué parámetros pasar.
```

### `search_calculators`

- The name "search_calculators" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Busca calculadoras de Hacé Cuentas por palabra clave (ej. "imc", "préstamo", "aguinaldo"). Devolvé el slug para usar luego con get_calculator o compute. Opcional: filtrar por category y limitar resultados.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `hacecuentas`:

```json

  "permissions": {
    "allow": [
      "mcp__hacecuentas__search_calculators",
      "mcp__hacecuentas__get_calculator"
    ],
    "ask": [
      "mcp__hacecuentas__compute"
    ],
    "deny": []
  }
}
```
