## 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**: 74/100
  - 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.
  - 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 (good).
  - Context-footprint check failed: tool/resource definitions use about 2777 tokens (~185/item across 15 items; 15 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 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).
  - 92% 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 15 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 16 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

Get spot prices

Live gold, silver and platinum spot prices in USD per troy ounce, with the time each was read and the gold-silver ratio.

### `list_products` (~75 tokens)

List tracked products

List the bullion products Bullion Price Check tracks (slug, name, metal, troy oz) with today's lowest listed dealer price for each. Use a slug with get_dealer_prices. This is the complete list: a product that is not listed is not tracked.

Input parameters:

### `get_dealer_prices` (~190 tokens)

- `metal` (string)

### `product_spec` (~166 tokens)

Coin and bar spec lookup

Official specs for a coin or bar: mint, country, fineness, gross and fine weight, pure metal content, denomination and series, with the source for each row and a fine-weight recompute check (gross x purity / 31.1034768). Covers the tracked products plus spec-only coins (pre-1933 $20/$10/$5 gold, Morgan and Peace dollars, PAMP 20 g and 10 g bars). Unknown fields, IRA eligibility and 1099-B reportability come back null and are listed in missing; nothing is estimated.

Input parameters:

### `quote` (~609 tokens)

Dealer buy/sell quote from spot

Price a dealer ticket from spot. Two classes: bullion (a tracked product) and scrap (weight + unit + karat or purity; purity is applied once). Buy offers use labeled default tiers as % of melt (bullion: conservative 96, target 97.5, aggressive 98.5; scrap: 90, 93, 95) or your own offer_pct; sell quotes use your margin rule: melt x (1 + margin_pct/100) + margin_usd. Returns unit and total (totals rounded once, from the unrounded unit), expiry, the spot used (spot_source, spot_asof), sell-side market percentiles and, for bullion buy offers, published dealer buyback bids as an anonymous benchmark (percentiles and counts only) when they exist. Never invents bids. Stateless.

Input parameters:

- `class` (string): bullion = a tracked coin or bar (default when product is given); scrap = metal by weight and karat or purity.
- `karat` (number): Scrap gold karat: 24=.999, 22=.9167, 18=.75, 14=.5833, 10=.4167 (others karat/24).
- `margin_pct` (number): Margin rule: percent over melt (sell) or under melt (buy). Not combined with tier/offer_pct.
- `margin_usd` (number): Flat USD per unit over melt (sell) or deducted (buy).
- `metal` (string): Scrap metal.
- `offer_pct` (number): Your own buy offer as % of melt; overrides the tier default.
- `product` (string): Tracked product slug from list_products (for example american-silver-eagle-1oz) or a name with its weight. A name only matches a product of the same weight.
- `purity` (number): Scrap fineness as a fraction (use instead of karat; required for silver or platinum scrap).
- `quantity` (integer): Number of units (bullion) or identical scrap lots.
- `side` (string): sell = you sell to a customer; buy = you buy from a customer. Default: buy for scrap or when tier/offer_pct is given, else sell.
- `spot` (number): Optional spot price in USD per troy oz to use instead of Bullion Price Check's latest reading (gold-api.com). The answer labels it spot_source=caller.
- `spot_asof` (string): Optional ISO time of the spot you passed in, echoed back as spot_asof.
- `tier` (string): Buy offer default tier (% of melt). Buy quotes without tier, offer_pct or margins use target.
- `unit` (string): Scrap weight unit: g = gram, dwt = pennyweight, ozt = troy ounce.

- `weight` (number): Scrap gross weight.

### `benchmark_premium` (~240 tokens)

Premium benchmark vs the US market

Benchmark your asking price (or premium %) for one tracked product against today's listed US dealer asks: your premium over spot, the market 25th percentile, median and 75th percentile premium, your percentile rank, and the Bullion Premium Index row (CC BY 4.0) with its dealer count. Aggregates only: no dealer is named.

- `spot_asof` (string): Optional ISO time of the spot you passed in, echoed back as spot_asof.
- `your_premium_pct` (number): Your premium over spot in percent (use instead of your_price).

### `value_inventory` (~208 tokens)

Inventory valuation

Value a list of inventory lots of tracked products at melt (spot x metal content) and at today's median listed US dealer ask, with cost basis and unrealized gain against melt when you give it. Up to 50 lots. On REST pass lots as JSON or as sku:qty[:cost_basis] items joined by commas.

Input parameters:

Returns the state's status (exempt, partial, taxable or no_sales_tax), a plain-English explanation, the threshold logic, the official source URL and the last_reviewed date, from the same table as the Bullion Price Check sales tax guide. General information, not tax advice. GET /api/v1/sales-tax lists all 51.

Input parameters:

- `amount` (number): Purchase amount in USD for the whole sale (optional). For a per-coin threshold (New Jersey) give the value of one coin.
