## Quality 89/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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`: 7 of 7 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: list_repair_types (idempotentHint, openWorldHint); get_repair_cost_guide (idempotentHint, openWorldHint); get_repair_cost_estimate (idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 884 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: 7, about 884 tokens to load them all
- tool set hash: 0c159b018c12b17bf7102b63ad4d377c
- badge: [![protogrid quality](https://protogrid.dev/badge/com.carrepaircostestimator/cost-estimator.svg)](https://protogrid.dev/servers/com.carrepaircostestimator/cost-estimator)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (7)

- `decode_vin`: Decode a 17-character Vehicle Identification Number (VIN) into year, make, model, trim, body style, and manufacturer. Use before estimate_vehicle_value to get exact vehicle details.
- `estimate_vehicle_value`: Estimate the current US market value (USD) of a vehicle from year, make, model, and optional trim. Deterministic model: base price by make, trim multiplier, age-based depreciation. Useful to judge whether a repair is worth the cost.
- `get_repair_cost_estimate`: Estimate the cost of a car repair job (parts + labor, USD, US national averages 2026) by make and repair type. Returns low/high ranges for parts, labor, and total. Use list_makes_models and list_repair_types to discover valid slugs.
- `get_repair_cost_guide`: Get the full editorial cost guide for a repair type: direct answer, price range, cost breakdown table, price factors, failure symptoms, and FAQs (US market, 2026). Use list_repair_guides to discover slugs.
- `list_makes_models`: List all supported car makes and their models (slugs, EV flag, price multiplier). Use the make_slug values with get_repair_cost_estimate and list_repair_types.
- `list_repair_guides`: List all editorial repair cost guides (slug, title, category, price range). Optionally filter by category: body, mechanical, glass-wheels, or electrical.
- `list_repair_types`: List the repair job types available for cost estimates (slugs, typical parts cost, labor hours). Pass a make_slug to get only the jobs applicable to that make (EVs skip ICE-only jobs).
