## Changes things (1)

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

### `decode_vin`

- 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
Decode a Vehicle Identification Number (VIN) to get vehicle details.

    Returns make, model, year, body class, engine info, safety features,
    and other attributes encoded in the 17-character VIN.

        vin: A 17-character Vehicle Identification Number (e.g. '1HGBH41JXMN109186').
    
```

## Only reads (5)

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

```untrusted-server-text
Get complaint counts by vehicle component for a specific make/model/year.

    Shows which parts of the vehicle consumers report the most problems with
    (e.g. brakes, engine, electrical system). Useful for identifying systemic
    vehicle defect patterns.

    Args:

Description, as the server wrote it:

```untrusted-server-text
Get consumer complaints about vehicles filed with NHTSA.

    Search for safety complaints by make, model, and/or year. Returns
    complaint descriptions, components involved, and crash/injury data.
    At least one filter (make, model, or year) should be provided.

    Args:
        make: Vehicle manufacturer name (e.g. 'Toyota', 'Ford').
        model: Vehicle model name (e.g. 'Camry', 'F-150').

    and alcohol-involved crashes.

    Args:
        state: Two-digit state FIPS code (e.g. '06' for California, '48' for Texas)
            or two-letter state abbreviation (e.g. 'CA', 'TX').
        year: Year for statistics (e.g. 2022). Defaults to the most recent available year.
    
```

### `get_recalls`

Description, as the server wrote it:

```untrusted-server-text
Get a vehicle safety profile using national complaint and recall trends.

    NHTSA complaints are not geocoded by state, so this returns national-level
    trends as context for local community safety assessments. Includes the most
    recent recalls and top complained-about vehicle makes.

    Args:
        state: Two-letter state abbreviation (e.g. 'CA', 'TX'). Used for crash
            statistics; complaint data is national.
    
```
