## Quality 80/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: 64 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_korean_real_estate_transactions (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 908 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: 1, about 908 tokens to load them all
- tool set hash: 66bbd1cebdd3590d6ccfb4ff8837d290
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.goyo-studio/korean-real-estate-mcp.svg)](https://protogrid.dev/servers/io.github.goyo-studio/korean-real-estate-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (1)

- `get_korean_real_estate_transactions`: 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.
