## Quality 69/100 (needs work)

### 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: 86 (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
- pass `tools.annotations`: 10 of 10 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_specs_full (destructiveHint, idempotentHint); search_cars (destructiveHint); get_specs (destructiveHint); …
- pass `tools.token_cost`: about 2,935 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 28 tool changes in 30 days
- fail `stability.rug_pull`: 4 tools kept their name but changed most of their description in 30 days; review before trusting them

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

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

- tools: 10, about 2,935 tokens to load them all
- tool set hash: 42f7a18002dd49b13c9b02218629e357
- tools last changed: 2026-10-18T23:46:57.400Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.cars-data/car-specs-api.svg)](https://protogrid.dev/servers/com.cars-data/car-specs-api)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-18 `get_specs` changed (description)
  - before: Full localized specs for one vehicle variant, in any of 20 languages — 224 spec types covering engine & fuel, performance, EV/hybrid, safety, comfort & interior, exterior, chassis, dimensions & weights, consumption (WLTP/NEDC). Each spec carries a confidence score; the response carries last_synced_at — surface both so you don't overstate certainty. This answers from a fixed 40-car demo set. For the full 103,372-variant catalogue call get_specs_full — paid per call with x402 (USDC on Base), $0.05, no key, no account.
