## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `calculate_shipping`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use when the user asks for supported auction-to-port shipping pricing for a known vehicle. Supply either VIN or lot_number; optionally narrow the destination with port or port_id. Availability depends on auction location and route data.
```

## Only reads (7)

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

### `get_api_usage`

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

Description, as the server wrote it:

```untrusted-server-text
Use to inspect request usage and current plan limits for the supplied X-API-Key. This is account/API-quota metadata, not vehicle data.
```

### `get_related_vehicles`

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

Description, as the server wrote it:

```untrusted-server-text
Use after identifying a specific vehicle to retrieve related supported auction records for comparison or discovery. Do not use as a substitute for a broad filtered inventory search.
```

### `get_vehicle`

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

Description, as the server wrote it:

```untrusted-server-text
Use when the user already has a VIN, lot number or supported slug and needs the current normalized vehicle record. Request include history and/or vin_lots when the same tool call should also return retained sale history or other known auction lots for the same VIN.
```

### `get_vehicle_filters`

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

Description, as the server wrote it:

```untrusted-server-text
Use before building a dynamic search UI or validating source-backed filter choices. Returns current filter metadata; it does not search inventory itself.
```

### `get_vehicle_history`

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

Description, as the server wrote it:

```untrusted-server-text
Use for retained Copart + IAAI auction appearances for one supported vehicle. This is auction-specific history, not complete ownership, registration or accident history.
```

### `list_auction_locations`

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

Description, as the server wrote it:

```untrusted-server-text
Use to resolve supported auction yards, branches or facilities and their location metadata. Use calculate_shipping when the user needs auction-to-port pricing instead.
```

### `search_auction_vehicles`

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

Description, as the server wrote it:

```untrusted-server-text
Use for broad inventory discovery, filtering and incremental synchronization across supported Copart and IAA / IAAI records. For one known VIN or lot use get_vehicle; for retained auction appearances use get_vehicle_history.
```
