## Trust

- hygiene: 100
- liveness: 99
- freshness: 65

- drivers: +repository +namespace-matches-repo +website +reachable +uptime-97% ~updated-101d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## 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: charm_lookup (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); charm_list_makes (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 334 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: 2, about 334 tokens to load them all
- tool set hash: 9d0ca42ffca1202669adb95a733f5141
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.bitMacrocode/charm.svg)](https://protogrid.dev/servers/io.github.bitMacrocode/charm)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (2)

- `charm_list_makes`: List all vehicle manufacturers covered by CHARM (1982-2013). Use to check coverage before a lookup.
- `charm_lookup`: Look up verified OEM part numbers, torque specs, fluid capacities, and service procedures for vehicles 1982-2013.

    Returns structured data sourced directly from factory service manuals (not model-generated).
    Provide year+make+model when known for a precise, isolated answer.

    Args:
        query: What you want to know (e.g. "front brake caliper part number", "spark plug gap", "engine oil capacity")
        year: 4-digit year, 1982-2013
        make: Manufacturer (e.g. "Ford", "Honda", "Chevy Truck")
        model: Model name (e.g. "Taurus X", "Civic", "Silverado")
        system: Optional system filter (e.g. "brakes", "engine", "electrical")
