## Quality 85/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 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`: 5 of 5 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_endpoint (idempotentHint); get_plans_and_limits (idempotentHint); get_doc_page (idempotentHint); …
- pass `tools.token_cost`: about 720 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: 5, about 720 tokens to load them all
- tool set hash: a928bb09fba46289b975e6945bf6c934
- badge: [![protogrid quality](https://protogrid.dev/badge/com.marketcheck/docs.svg)](https://protogrid.dev/servers/com.marketcheck/docs)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (5)

- `get_doc_page`: Fetch one full documentation page as Markdown, including resolved parameter tables and curl examples. Use a 'Page:' URL or path returned by search_docs or get_endpoint, e.g. '/docs/api/cars/inventory/inventory-search'. UK pages are under '/uk/docs/...'.
- `get_endpoint`: Exact reference for one REST endpoint: every query parameter (name, type, description, required, default), a real sample request, and a truncated real sample response. Use the path as shown by list_endpoints, e.g. '/v2/search/car/active'.
- `get_plans_and_limits`: Current published MarketCheck rate plans: per-call pricing, monthly quotas, and rate limits for a region, sourced from the live plan list (authoritative over docs). NA prices in USD, UK in GBP.
- `list_endpoints`: List every documented MarketCheck REST endpoint: method, path, one-line title, region, and docs URL (~73 endpoints across US/UK cars, dealers, VIN decode, history, valuations).
- `search_docs`: Semantic search over the complete MarketCheck API documentation, current rate plans, and API policies (2,000+ indexed sections). Returns the most relevant excerpts, each with its source page URL and endpoint. Use this first for any question about endpoints, parameters, authentication, errors, plans, or terms.
