## Trust

- hygiene: 80
- liveness: 100
- freshness: 100
- provenance: 55
- drivers: +dns-namespace +website +reachable +uptime-100% +updated-7d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 89/100 (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: 100 (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`: 8 of 8 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,339 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

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

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 6 of the 7 days needed

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

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

- tools: 8, about 1,339 tokens to load them all
- tool set hash: db88884856800865f3839d34ac89beff
- tools last changed: 2026-10-17T15:27:44.141Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.wiacode/wiacode.svg)](https://protogrid.dev/servers/com.wiacode/wiacode)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (8)

- `generate_wia_code`: 텍스트나 링크를 WIA Code 이미지(PNG)로 만든다. 실루엣마다 용량이 다르므로 긴 내용은 square(가장 큼) 를, 짧은 링크는 아무 실루엣이나 쓰면 된다. 용량을 넘으면 어떤 실루엣이 가능한지 알려준다.
- `generate_wia_code_card`: 연락처(명함)를 표준 vCard 로 담은 WIA Code 를 만든다. 스캔하면 폰이 연락처 저장을 제안한다.
- `generate_wia_code_event`: 일정을 표준 iCalendar 로 담은 WIA Code 를 만든다. 스캔하면 캘린더에 추가된다. 시각은 "2026-09-01 19:00" 형식으로 준다.
- `generate_wia_code_wifi`: 와이파이 접속 정보를 WIA Code 로 만든다. 스캔하면 비밀번호를 입력하지 않고 바로 접속된다. 카페·사무실·숙소 안내에 쓴다. 개방망이면 security 를 nopass 로 준다.
- `get_wia_code_info`: WIA Code 가 무엇이고 QR 과 어떻게 다른지, 어떤 실루엣과 용량이 있는지 알려준다. 코드를 만들기 전에 이걸 먼저 불러 실루엣과 용량을 확인하면 실패를 줄일 수 있다.
- `pin_code_decode`: Turn a WIA Pin Code (12-digit v2 or 9-digit v1, dashes optional, a leading country calling code such as 082- is ignored) into latitude/longitude. v2 returns the cell centre (error within about ±10 m lat / ±20 m lng); v1 is a coarser legacy code.
- `pin_code_encode`: Turn a latitude/longitude into a WIA Pin Code (12 digits, e.g. 708-702-851-863 for central Seoul). Also returns the 9-digit v1 code, which is always the first 9 digits of the v2 code. Works offline-style: pure calculation, no lookup.
- `pin_code_nearby`: List the WIA Pin Code cells around a point or a code, nearest first, with distance and direction. Useful for "which codes cover this building/plaza". Give either code, or lat+lng. Radius 10–200 m.
