Category Maps and Location
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability66
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 338 tokens (~169/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management33
- Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
address_korea_lookup Look up a Korean road-name address ~128
Normalize a Korean address using the Korean government road-name address data: returns road-name address, lot-number (jibun) address, postal code, building name and the official English road-name address. Does not return coordinates. The keyword is sent to the government address service via WIA Address. (한국어: 도로명·지번·우편번호·공식 영문 표기를 조회합니다.)
| Name | Type | Req | Description |
|---|---|---|---|
| keyword | string | yes | Korean address keyword, e.g. '서울 강남구 테헤란로 152' or '강남파이낸스센터' |
No output schema declared.
No examples provided.
address_translate Translate a postal address ~188
Translate or transliterate a street address into another language using WIA Address (OpenStreetMap Nominatim geocoding; for Korean addresses also the Korean government road-name address API). Returns structured fields, not an official postal confirmation. The address text is sent to third-party geocoding services. Do not use for mail delivery decisions without verifying with the local postal service. (한국어: 주소를 다른 언어 표기로 변환합니다.)
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | Full street address in any language, e.g. '서울 강남구 테헤란로 152' or '1600 Pennsylvania Avenue NW, Washington DC' |
| from | string | yes | Language code of the input address (ISO 639-1/2, e.g. ko, en, ja) |
| to | string | yes | Language code for the output (e.g. en, ja, ko) |
No output schema declared.
No examples provided.
How do I install the WIA Address MCP server?
WIA Address is a hosted endpoint at https://wiaaddress.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
