## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `estimate_us_duty`

- The description's first verb is "apply": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Applies the governing ad valorem rate for an HTS code to a customs value and returns the indicative duty, with the free-trade rate shown separately when the origin qualifies. It states plainly what is excluded rather than presenting a total that looks complete. Use it for a directional landed-cost figure, never as a customs declaration.
```

## Only reads (2)

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

### `find_hts_code`

- The name "find_hts_code" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the official US Harmonized Tariff Schedule by plain-language product description and get back candidate HTS lines with their duty rates. Classification is the hard part of importing and the usual place a costly mistake is made, so this returns several candidates with their descriptions rather than pretending there is one obvious answer.
```

### `lookup_us_duty_rate`

- The name "lookup_us_duty_rate" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Given a US HTS code, returns the duty rate that actually applies, resolving the common trap that rates sit on the 8-digit line while the 10-digit statistical lines underneath are blank and inherit. Optionally pass the country of origin to see whether a free-trade rate is available. Always reports what is excluded, because trade remedies such as Section 301 are not in this data and can dwarf the base rate.
```
