## 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**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - 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**: 59/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 2464 tokens (~246/item across 10 items; 10 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 50/100
  - Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 97/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 90% 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 10 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 11 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).

### `search_folsn_products` (~420 tokens)

폴슨 상품 검색 / Search Folsn products

폴슨(folsn)이 네이버 스마트스토어에서 직접 파는 상품을 상품 이름·옵션(용량·수량·색상·모델 번호)으로 찾습니다. 결과마다 판매가(원)·배송비·묶음 수량과 개당 환산가·재고 상태·구매 주소·가격 기록 시각·출처를 따로 돌려줍니다. 다른 쇼핑몰 가격이나 전체 최저가는 돌려주지 않습니다. 검색어는 한국어 상품명(브랜드 + 제품명 + 용량·수량)이 가장 잘 맞고, 등록된 영어 브랜드·상품명도 일부 지원합니다. matchStatus=needs_clarification이면 clarificationFields의 옵션을 사용자에게 되물으세요. 결과가 없으면 hint의 내용을 사용자에게 전해 주세요. 예: {"query": "쿤달 칫솔 16입", "limit": 5}
Search products sold directly by Folsn on its own Naver Smart Store (Korea) by product name and option (volume, count, color, model number). Each result returns price in KRW, shipping fee, bundle quantity with unit price, stock status, purchase URL, the time the price was recorded, and the source as separate fields. It does not return other stores' prices or market-wide lowest prices. Korean product names (brand + product + volume/count) match best; selected English brand and product names also work. Unknown English words remain unchanged. If matchStatus=needs_clarification, ask the user about the options in clarificationFields. If there are no results, relay the hint to the user. Example: {"query": "클로란 피오니 샴푸 400ml", "limit": 5}

Input parameters:

- `limit` (integer): 최대 결과 수(1~10) / max results
- `query` (string, required): 상품 이름·옵션 검색어 또는 sku / product name and options, or sku

폴슨 상품 판매 조건 / Get Folsn product offer

검색 결과의 sku(스마트스토어 상품 번호)로 폴슨 상품 한 건의 판매 조건을 가져옵니다: 판매가(원)·배송비·쿠폰(현재는 수집하지 않아 null)·묶음 수량과 개당 환산가·재고 상태·구매 주소·가격 기록 시각·출처. 예: {"product_id": "13300090680"}
Get the sale terms of one Folsn product by its sku (Smart Store product number) from search_folsn_products: price in KRW, shipping fee, coupon (not collected yet, null), bundle quantity and unit price, stock status, purchase URL, price record time and source. Example: {"product_id": "13300090680"}

Input parameters:

- `product_id` (string, required): 검색 결과의 sku(스마트스토어 상품 번호) / sku from search_folsn_products

Output parameters:

- `notice` (string)

### `get_catalog_offers` (~186 tokens)

상품에 연결해 확인한 판매처 관측만 반환합니다: 공개 판매가·배송비·구매 링크·관측 시각. 관측이 30일보다 오래되었거나 확인되지 않은 값은 null입니다. 미연결 오퍼·시드 가격은 상품에 붙이지 않습니다. 폴슨이 수집한 판매처만 다루므로 가장 낮은 값도 전체 최저가가 아닙니다. Linked, checked seller observations only: public price, shipping fee, store link and observation time; fields stay null when unknown or older than 30 days. Unlinked offers and seed prices are never attached. Only sellers Folsn collected are covered, so the lowest value here is not a market-wide lowest price.

- `product_id` (string, required): search_catalog_products의 productId

Output parameters:

- `notice` (string)
- `offers` (array)

Output parameters:

- `notice` (string)
- `products` (array)
- `query` (string)
- `totalCount` (integer)

### `get_beauty_product_detail` (~114 tokens)

화장품 기준 원장 및 전성분 상세 / Get beauty product detail

출처 미검증 화장품 원장의 기본 정보만 조회합니다. 인허가·전성분은 개별 근거 확인 전까지 비웁니다. Get basic catalog fields; regulatory and ingredient claims are withheld pending verification.

Input parameters:

- `barcode`: 880 바코드(GTIN-13) / 880 barcode
- `beauty_id`: 화장품 고유 ID (BP_...) / unique beauty ID
- `product_name`: 상품명 검색어 / product name

사용자가 직접 입력한 성분명을 분류합니다. 상품 원장의 전성분 출처와 피부 적합성은 확인되지 않았습니다. Classify user-supplied ingredient names; no product-specific ingredient or skin-safety claim.

Input parameters:

- `ingredients_text`: 전성분 텍스트 (콤마 구분) / comma-separated ingredients text
- `product_name_or_id`: 상품명 또는 beauty_id / product name or beauty_id

## Common questions

### What is the Folsn Product Catalog MCP server?

Folsn Product Catalog is an MCP server listed in the public MCP registry as com.folsn.mcp/own-store-products. Search recorded Folsn product catalogs with linked public seller prices, shipping fees and URLs. This page covers its hosted endpoint (https://mcp.folsn.com/public/mcp).

### Is the Folsn Product Catalog MCP server safe to use?

Folsn Product Catalog scores 77 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Folsn Product Catalog MCP server expose?

Folsn Product Catalog exposes 10 tools: search_folsn_products, get_folsn_product_offer, search_catalog_products, get_catalog_product, get_catalog_offers, and 5 more. Their descriptions and schemas cost roughly 1,557 tokens of context every time the server is loaded.

### Does the Folsn Product Catalog MCP server require authentication?

No. We connected to Folsn Product Catalog without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Folsn Product Catalog MCP server still maintained?

Folsn Product Catalog is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the Folsn Product Catalog MCP server?

VerifyMCP ran 13 checks on Folsn Product Catalog, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
