## 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: find_crane_rental_companies (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_crane_rental_prices (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); check_availability_by_plz (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 653 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)

## Tools (4)

- `check_availability_by_plz`: Check real-world supplier availability per crane type for a given German PLZ. Returns, for each crane type in the catalog, the count of active suppliers within 50 km and 100 km plus the distance to the nearest supplier. Use this BEFORE recommending a crane type so you can prefer locally available options when functionally equivalent — transport for a crane >100 km adds €800-1500 to the customer's bill. Decision rule: when the functionally ideal type has no supplier within 50 km but a substitutable type does, recommend the local one and explain why; only expand the radius when the ideal type uses specialty equipment that no other type can replace (e.g. Spinnenkran for tight-access glass mounting, Raupenkran for soft terrain).
- `find_crane_rental_companies`: Find crane rental companies (Kranvermietung) in a city in Germany or Austria. Returns company name, Google rating and a link to request a free quote via KranVergleich (several suppliers with one request, offers can be compared). Sorted by Google rating (descending); no paid placement.
- `get_crane_rental_prices`: Get typical rental prices for cranes in Germany. Returns day/week/month price ranges for all 8 crane types or a specific type.
- `recommend_crane_type`: Recommend the best crane type for a project based on weight, height, and task. Returns the recommended crane with reasoning and price estimate.
