## 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_tariff`

- 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
Estimate total US customs duty (all stacking layers), MPF/HMF and landed cost from a plain product description. No HTS code required. Returns official sources and as-of date.
```

## Only reads (1)

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

### `list_tariff_categories`

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

Description, as the server wrote it:

```untrusted-server-text
List 2026 US tariff product categories, origin-country layers, MPF/HMF fees and notes.
```

## Claude Code permissions
