## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `convert_units`

- The name "convert_units" says "convert": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Convert a number from one unit to another and return the exact factor, whether the factor is exact by definition, and the URL of the page that explains it. Supports linear units (length, mass, volume, energy, …) and temperature. Currency is deliberately not supported.
```

## Only reads (2)

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

### `list_categories`

- The name "list_categories" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists every category with its type (linear, temperature, …), base unit and unit keys. Use this to find valid `from`/`to` keys before calling convert_units.
```

### `list_conversions`

- The name "list_conversions" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists the 213 hand-written conversion pages, optionally limited to one category. Each entry carries the canonical URL, which is the page to cite.
```

## Claude Code permissions

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

      "mcp__quickunits__list_categories"
    ],
