## Trust

- hygiene: 80
- liveness: 99
- freshness: 100
- provenance: 45
- drivers: +website +reachable +uptime-97% +updated-9d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 85/100 (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: 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`: 4 of 4 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: drone_flight_check (destructiveHint, idempotentHint); get_receipt (destructiveHint, idempotentHint, openWorldHint); drone_rule_table (destructiveHint, idempotentHint); …
- pass `tools.token_cost`: about 1,100 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: 4, about 1,100 tokens to load them all
- tool set hash: 399a1cb92d7ee94dda92c935c8c964ba
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.mk-career-planning/jp-drone-airspace.svg)](https://protogrid.dev/servers/io.github.mk-career-planning/jp-drone-airspace)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `catalog`: List the tools of this server with prices, data sources, licensing, daily limits and data freshness.
- `drone_flight_check`: Which Japanese drone rules apply at this point, time and height? Returns applies / does_not_apply / possible_check_required / unknown per check (DID 2020, 150 m, night, airport screening, Small UAS Act facilities, MLIT emergency airspace, flight methods, 25 kg), the category (I/II/III/unknown) and permission_needed, with a receipt per check. Reference only; uncertain = check DIPS; no applications prepared.
- `drone_rule_table`: Which rules and thresholds does drone_flight_check use? Returns the rule table (specified flight triggers under Civil Aeronautics Act Art. 132-85/86, which can be waived with certificates), category definitions, screening radii and their basis, the review guideline version and sources. Reference only.
- `get_receipt`: Re-fetch the stored result of a settled paid call by its receipt_id, for when the response was lost after payment. Free. Unknown or unsettled receipt ids return RECEIPT_NOT_FOUND. Results are kept for 90 days after settlement.
