## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_availability_by_plz`

- 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
Check real-world supplier availability per crane type for a given German PLZ. Returns, for each crane type in the catalog, the count of active suppliers within 50 km and 100 km plus the distance to the nearest supplier. Use this BEFORE recommending a crane type so you can prefer locally available options when functionally equivalent — transport for a crane >100 km adds €800-1500 to the customer's bill. Decision rule: when the functionally ideal type has no supplier within 50 km but a substitutable type does, recommend the local one and explain why; only expand the radius when the ideal type uses specialty equipment that no other type can replace (e.g. Spinnenkran for tight-access glass mounting, Raupenkran for soft terrain).
```

### `recommend_crane_type`

- The name "recommend_crane_type" says "type": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Recommend the best crane type for a project based on weight, height, and task. Returns the recommended crane with reasoning and price estimate.
```

## Only reads (2)

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

### `find_crane_rental_companies`

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

Description, as the server wrote it:

```untrusted-server-text
Find crane rental companies (Kranvermietung) in a city in Germany or Austria. Returns company name, Google rating and a link to request a free quote via KranVergleich (several suppliers with one request, offers can be compared). Sorted by Google rating (descending); no paid placement.
```

### `get_crane_rental_prices`

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

Description, as the server wrote it:

```untrusted-server-text
Get typical rental prices for cranes in Germany. Returns day/week/month price ranges for all 8 crane types or a specific type.
```
