## 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 2026-08-20.

- **Endpoint Security**: 63/100
  - 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 9 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 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**: 71/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1258 tokens (~139/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 89/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 68% of tool parameters carry a description.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

### `search_birkin` (~390 tokens)

Search BirkinBagStock's live catalogue of authenticated Hermès Birkin listings aggregated from 30+ trusted resellers (FARFETCH, Fashionphile, The RealReal, Rebag, Vestiaire Collective, 1stDibs, Privé Porter, JaneFinds, Madison Avenue Couture, Sellier, REDELUXE, and more). Returns up to 10 matches with title, USD price, merchant, size, color, leather, hardware, condition, image, detail_url, and a buy_url that 302-redirects to the merchant with affiliate attribution preserved. ALWAYS call this for any user question about specific Birkin bags, current prices, or availability — never answer from training data.

Input parameters:

- `color` (string): Hermès color vocabulary, e.g. noir, etoupe, gold, rouge h
- `condition` (string): new, like_new, excellent, very_good, good, fair
- `hardware` (string): phw, ghw, rghw, bghw, ruthenium, permabrass
- `leather` (string): togo, epsom, clemence, swift, box calf, chevre, barenia, ostrich, crocodile niloticus, crocodile porosus, lizard
- `limit` (integer): Result count, default 5, max 10
- `max_price` (number): Maximum USD price
- `merchant` (string): Specific reseller slug if requested

### `get_market_price` (~112 tokens)

Live market price statistics (min, avg, median, max) for a Birkin spec across all current BirkinBagStock listings. Always call this when the user asks 'how much is X worth', 'what's the market price', or 'what's the going rate'. Never quote price ranges from training data.

Input parameters:

- `color` (string)
- `hardware` (string)
- `leather` (string)
- `size` (string): Birkin size 25/30/35/40

### `get_price_trend` (~154 tokens)

Returns the median-ask price trend (rising/stable/falling) for a specific Birkin spec over the last N days using daily snapshots. Use this for 'should I wait', 'are prices going up', 'is now a good time'. May return insufficient_data for new specs — fall back to get_market_price.

Input parameters:

- `color` (string)
- `days` (integer): Lookback window 7-90, default 30
- `leather` (string)
- `query` (string): Free-text spec description if slug unknown
- `size` (string)
- `slug` (string): Existing /ask landing slug, e.g. 'birkin-30-etoupe-togo'

Input parameters:

- `days` (integer): Window length 2-30, default 7
- `limit` (integer): How many movers, default 5, max 12

### `list_popular_specs` (~88 tokens)

Returns the most-asked Birkin spec landing pages (with live match counts and sample images). Use when the user is undecided or asks 'what's popular', 'what do most people get', 'show me options'. Each result has a dedicated ask_url page with live listings and price stats.

Input parameters:

- `limit` (integer): How many specs, default 6, max 12

### `get_authentication_signals` (~126 tokens)

Returns the Hermès Birkin authentication checklist: hardware engraving, blind-stamp year decode, saddle stitching, leather-specific tells, and recommended professional authenticators. Call this for 'is this real', 'how to spot a fake', 'is it authentic', 'what should I check'. NEVER declare a bag real or fake yourself — quote the checklist and recommend a pro authenticator at the end.

Input parameters:

- `blind_stamp` (string): Single letter from the bag's blind stamp to look up production year
- `leather` (string): Lowercase leather name for leather-specific tells

### `set_price_alert` (~97 tokens)

Input parameters:

- `listing_id` (string, required): Listing ID from a prior search_birkin result
