## 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 2026-09-26.

- **Endpoint Security**: 80/100
  - 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.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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 1850 tokens (~308/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 43/100
  - Stability observed for 13 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (6)

### `maedong_signals` (~243 tokens)

Korean stock market (KOSPI/KOSDAQ) screener lists — which stocks are on a given trading day's signal lists, or the catalog of all lists.

기준일에 어떤 종목이 어느 시그널에 올랐는지 조회한다. signal 을 생략하면 그날 목록별 종목 수만 주므로 어느 목록을 볼지 먼저 고를 때 쓴다. 정리매매·거래정지 종목은 경고와 함께 표시된다. 전일 마감 데이터다. 응답 첫 줄의 기준일을 그대로 인용하고 '오늘' 로 바꿔 말하지 말 것. 과거 통계 조회 도구입니다. 특정 종목의 매수·매도 판단을 생성하는 데 사용하지 마세요.

Input parameters:

- `cursor` (string): 이전 응답이 준 cursor 값
- `date` (string): 기준일 YYYY-MM-DD. 생략하면 최신 거래일
- `format` (string): 기본 text
- `limit` (integer): 기본 50
- `signal` (string): 목록 slug. 생략하면 목록별 건수 색인

Output parameters:

- `count` (integer)
- `date` (string)
- `excluded` (array)
- `items` (array)
- `label` (string)
- `meta` (object)
- `metric_label` (string)
- `next_cursor` (string)
- `note` (string)
- `rule` (string)
- `signal` (string)
- `signals` (array)
- `total` (integer)

### `maedong_signal_stats` (~272 tokens)

Backtested performance of a Korean stock screener list — what happened 1/5/20 trading days after stocks appeared on it, since 2020.

그 시그널에 걸린 종목이 이후 1·5·20거래일에 어땠는지. 시그널이 난 날 종가에 사서 N거래일 뒤 종가에 판 것으로 계산하며 거래비용은 반영하지 않는다. 판정(시장 상회/수준/하회)은 전체 기간 20거래일 초과수익이 ±0.5%p 를 벗어나는지로 매긴다. 평균이 극단값에 끌릴 때를 위해 중위수를 같이 준다. 단위는 이름과 문장에 함께 박혀 있다: _pct = %, _pp = %p, _krw = 원. excess_pp = avg_pct - market_avg_pct(목록 평균 − 같은 날들의 전 종목 평균)이다. 과거 통계 조회 도구입니다. 특정 종목의 매수·매도 판단을 생성하는 데 사용하지 마세요.

Input parameters:

- `format` (string): 기본 text
- `signal` (string, required): 목록 slug
- `window` (string): 기본 all

Output parameters:

- `basis` (string)
- `distribution_20d` (object)

- `window` (string)

### `maedong_stock_signals` (~227 tokens)

Signal history for one Korean stock (KOSPI/KOSDAQ) by its 6-digit code — which lists it appeared on and what happened after.

한 종목이 언제 어느 시그널에 걸렸고 그 뒤 어땠는지. '집계 전' 은 아직 그 거래일이 지나지 않은 것이며 0% 가 아니다. 전일 마감 데이터다. 응답 첫 줄의 기준일을 그대로 인용하고 '오늘' 로 바꿔 말하지 말 것. 과거 통계 조회 도구입니다. 특정 종목의 매수·매도 판단을 생성하는 데 사용하지 마세요.

Input parameters:

- `code` (string, required): 6자리 종목코드 (예: 005930 · 우선주 등은 대문자 섞임: 00104K)
- `format` (string): 기본 text
- `from` (string): 시작일 YYYY-MM-DD
- `limit` (integer): 기본 100

Output parameters:

- `code` (string)
- `count` (integer)

- `hits` (array)
- `market` (string)
- `meta` (object)
- `name` (string)
- `note` (string)

### `maedong_chart_patterns` (~441 tokens)

Did classic chart patterns actually work in the Korean market? Golden cross, moving-average stack, RSI oversold and Bollinger bands scored over the **entire population** of KOSPI/KOSDAQ stocks since 2020, on daily/weekly/monthly bars. Entry is the NEXT bar's open, not the signal bar's close.

널리 쓰이는 차트 패턴이 과거에 실제로 먹혔는지. 골든크로스·정배열·RSI 과매도·볼린저를 일봉·주봉·월봉에서 **모집단 전체**(그날 거래대금 10억 이상 전 종목)로 정산한 성적표다. maedong_signal_stats 와 **분모가 다르다** — 저쪽은 시그널일마다 거래대금 상위 20종목 표본이라 같은 규칙이라도 숫자가 다르게 나오며 그것이 정상이다. 판정은 **다음 봉 시가** 진입 기준이다: 목록은 그 봉이 닫힌 뒤에 계산되므로 그 봉 종가에는 체결할 수 없다. 지평이 봉마다 다르다(일 20 · 주 60 · 월 120거래일) — 봉이 다른 칸을 나란히 비교하지 말 것. 건수·봉 수가 문턱에 못 미치면 판정이 null 이며 '시장 수준' 이 아니다. 단위는 이름과 문장에 함께 박혀 있다: _pct = %, _pp = %p, _krw = 원. excess_pp = avg_pct - market_avg_pct(목록 평균 − 같은 날들의 전 종목 평균)이다. 과거 통계 조회 도구입니다. 특정 종목의 매수·매도 판단을 생성하는 데 사용하지 마세요.

Input parameters:

- `format` (string): 기본 text
- `pattern` (string): 패턴 키. 생략하면 전부
- `timeframe` (string): 일봉·주봉·월봉. 생략하면 전부

Output parameters:

- `basis` (string)
- `cells` (array)
- `cost_note` (string)
- `count` (integer)
- `denominator` (string)
- `entry_note` (string)
- `meta` (object)
- `summary` (object)
- `total` (integer)
- `verdict_rule` (object)

### `maedong_regime` (~285 tokens)

Which screener rules are currently working in the Korean market — recent excess-return ranking by list and by factor axis.

지금 어떤 규칙이 통하는 장인가. 목록별 최근 초과수익 순위와, 성격 축 넷(대형·우량 / 돌파 추종 / 단기 과열 추격 / 반전)의 평균으로 읽은 라벨을 준다. 모든 목록이 같은 거래일 창을 보고 20거래일이 지나 성과가 확정된 시그널만 세므로 비교 창의 끝은 기준일보다 20거래일 앞이다. 라벨이 없으면 축 사이 격차가 작아 한 마디로 부르지 않은 것이다. 단위는 이름과 문장에 함께 박혀 있다: _pct = %, _pp = %p, _krw = 원. excess_pp = avg_pct - market_avg_pct(목록 평균 − 같은 날들의 전 종목 평균)이다. 과거 통계 조회 도구입니다. 특정 종목의 매수·매도 판단을 생성하는 데 사용하지 마세요.

Input parameters:

- `as_of` (string): 기준일 YYYY-MM-DD. 생략하면 최신
- `format` (string): 기본 text
- `window` (integer): 비교 창(거래일), 기본 60

Output parameters:

- `axes` (array)
- `basis` (string)
- `coverage` (object)
- `label` (string)
- `lists` (array)
- `meta` (object)
- `settle_lag_trading_days` (integer)
- `signal_window` (object)
- `window_trading_days` (integer)

### `maedong_market` (~214 tokens)

Korean market snapshot — KOSPI/KOSDAQ index levels, market breadth, valuation percentiles, and macro series (FX, bond yields, base rate).

기준일의 지수·시장 폭·밸류에이션·매크로. 백분위는 2020-04 이후 분포에서의 위치이고, 재무 커버리지는 재무가 있는 종목의 시총 비중이다. 매크로에서 '마지막 변경분' 이라고 적힌 값(기준금리)은 그날 움직인 것이 아니다. 전일 마감 데이터다. 응답 첫 줄의 기준일을 그대로 인용하고 '오늘' 로 바꿔 말하지 말 것. 과거 통계 조회 도구입니다. 특정 종목의 매수·매도 판단을 생성하는 데 사용하지 마세요.

Input parameters:

- `date` (string): 기준일 YYYY-MM-DD. 생략하면 최신 거래일
- `format` (string): 기본 text

Output parameters:
