## 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 2026-11-05.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 1 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 61/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 790 tokens (~790/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 40/100
  - Stability observed for 12 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 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 1 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (1)

### `get_korean_real_estate_transactions` (~790 tokens)

Query official Korean real-estate transaction records (국토교통부 실거래가, MOLIT via data.go.kr) with a natural-language Korean address or apartment-complex name, e.g. '강남구 대치동 은마 아파트 매매'. Returns flat JSON: period statistics (avg/min/max price in KRW, or deposit/monthly-rent stats for rentals) plus individual transactions, newest first. For trend questions ('월별 추이', 'how did prices move'), pass groupBy=month to get stats_by_month[]; for a size condition ('전용 84', '국평'), pass an areaMin/areaMax band — both aggregate over the full matching set, unlike the row list which is capped at limit. Hint words inside q (아파트/오피스텔…, 매매/전세/월세) are auto-inferred as type/tradeType/rentSubtype; explicit fields always win. Ambiguous locations return HTTP 422 with candidates[] — pick one and retry. Unresolvable locations return 404. All inferences are disclosed in resolved_note; coverage gaps in missing_months. Terms (as-is, no warranty): https://realestate-api.goyostudio.io/terms — data may be corrected or cancelled after initial publication; not investment advice. PRICING: currently free within edge or app rate limits (50 requests / 10 seconds per IP). HTTP 429 with error RATE_LIMITED and a Retry-After header — wait that many seconds, then retry. x402-ready: a fixed micro-price per request (indicative $0.001–$0.01, USDC on Base) may be enabled later, after which unpaid requests receive HTTP 402 Payment Required per the x402 protocol (https://x402.org); agents with x402 support handle this automatically. Current pricing status: GET https://realestate-api.goyostudio.io/openapi.json → x-pricing.

Input parameters:

- `areaMax` (number): Maximum EXCLUSIVE area (전용면적) in ㎡, inclusive.
- `areaMin` (number): Minimum EXCLUSIVE area (전용면적) in ㎡, inclusive. Not supply area (공급면적). A '84 type' apartment is usually 84.0-85.9㎡, so pin it with areaMin=84 & areaMax=86.
- `endDate` (string): YYYY-MM inclusive. Default: current month.
- `groupBy` (string): Set to 'month' for stats_by_month[] — per-month aggregates over the full matching set. Required for trend/추이 questions: the transaction rows are capped at limit, so a trend cannot be rebuilt from the…
- `limit` (integer): Max transaction rows returned (default 100). Statistics always cover the full matching set regardless of limit.
- `q` (string, required): Natural-language Korean address and/or complex name. Max ~30 Korean characters (90 UTF-8 bytes), max 8 whitespace-separated tokens. Do not include period words ('최근 3개월' is ignored — use startDate/en…
- `rentSubtype` (string): Only with tradeType=rent. jeonse (전세) = deposit-only; wolse (월세) = has monthly rent.
- `startDate` (string): YYYY-MM inclusive. Default: 11 months before endDate (12-month window). Max range 24 months.
- `tradeType` (string): sale = 매매 (default), rent = 전월세 (jeonse + wolse combined unless rentSubtype filters).
- `type` (string): Property type. Default apartment unless inferred from q. rent is available only for apartment/officetel/rowhouse/detached; presale/land/commercial/industrial are sale-only.
