## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_recalls (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); local_vehicle_safety_profile (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_complaints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,003 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 1,003 tokens to load them all
- tool set hash: c5949e5842e993a78331aef7d70dd6ab
- badge: [![protogrid quality](https://protogrid.dev/badge/com.olyport/nhtsa.svg)](https://protogrid.dev/servers/com.olyport/nhtsa)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `complaint_trends_by_component`: 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:
        make: Vehicle manufacturer name (e.g. 'Toyota', 'Ford').
        model: Vehicle model name (e.g. 'Camry', 'F-150').
        year: Model year (e.g. 2023).
    
- `decode_vin`: 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.

    Args:
        vin: A 17-character Vehicle Identification Number (e.g. '1HGBH41JXMN109186').
    
- `get_complaints`: 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').
        year: Model year (e.g. 2023).
        limit: Maximum number of complaints to return (default 25).
    
- `get_crash_statistics`: Get fatal crash statistics from the NHTSA Fatality Analysis Reporting System (FARS).

    Returns fatal motor vehicle crash data for a state, including total
    fatalities, fatalities by person type (drivers, passengers, pedestrians),
    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`: Get vehicle safety recalls from NHTSA.

    Search for recalls by make, model, and/or year. Returns recall campaigns
    including the defect description, remedy, and affected vehicles.
    At least one filter (make, model, or year) should be provided.

    Args:
        make: Vehicle manufacturer name (e.g. 'Toyota', 'Ford', 'Honda').
        model: Vehicle model name (e.g. 'Camry', 'F-150', 'Civic').
        year: Model year (e.g. 2023).
    
- `local_vehicle_safety_profile`: 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.
