## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-23.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 66/100
  - AI-judged instruction clarity (good).
  - 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.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 33/100
  - Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (2)

### `address_translate` (~188 tokens)

Translate a postal address

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.)

Input parameters:

- `address` (string, required): Full street address in any language, e.g. '서울 강남구 테헤란로 152' or '1600 Pennsylvania Avenue NW, Washington DC'
- `from` (string, required): Language code of the input address (ISO 639-1/2, e.g. ko, en, ja)
- `to` (string, required): Language code for the output (e.g. en, ja, ko)

### `address_korea_lookup` (~128 tokens)

Look up a Korean road-name address

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.)

Input parameters:

- `keyword` (string, required): Korean address keyword, e.g. '서울 강남구 테헤란로 152' or '강남파이낸스센터'
