## 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 2026-09-22.

- **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**: 69/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1757 tokens (~87/item across 20 items; 20 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% 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 20 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 21 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).

### 2026-09-22 (score 69, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (20)

### `resolve_jurisdiction` (~88 tokens)

Resolve Jurisdiction

Where is this going? Resolve a ship-to (e.g. 'US', 'US-CA', 'UK', 'FR', 'EU-DE', 'JP') to one of the 18 markets and its rule set (13 rule sets; the six EU markets share one). UK is the label; machine fields carry the ISO code GB.

Input parameters:

- `ship_to` (string, required)

### `resolve_actor` (~79 tokens)

Resolve Actor

Who is asking? Brand, manufacturer, retailer or distributor (business to business); auditor (read-only); agent (inherits the class of the credential it presents — none returns DENY_UNLICENSED_AGENT). The consumer is never the counterparty. Returns communication_class: trade_information or public.

- `product_type`

### `get_label_and_claims` (~73 tokens)

Get Label And Claims

- `market` (string, required)
- `product_type`
- `query`

### `get_item` (~74 tokens)

- `gtin`
- `limit` (integer)
- `market` (string, required)

Input parameters:

- `decision_id` (string, required)
- `gtin` (string, required)
- `market`

### `get_price` (~70 tokens)

Input parameters:

- `decision_id` (string, required)
- `gtin` (string, required)
- `market`

### `get_product_documents` (~75 tokens)

- `gtin` (string, required)
- `market`
- `quantity` (integer, required)
- `ship_to`

### `a2a_handoff` (~99 tokens)

A2A Handoff

Hand the buyer to the right agent over Agent-to-Agent (A2A): with an allow decision the order intent goes to the counterparty's agent (envelope + card URL); with a deny, the market agent of the ship-to (the regulator's home page beside it) — a referral, never a sale to a consumer.

Input parameters:

- `counterparty_card_url`
- `decision_id`
- `intent_id`

### `get_safety_label` (~68 tokens)

### What tools does the A2A Cosmetics MCP server expose?

A2A Cosmetics exposes 20 tools: resolve_jurisdiction, resolve_actor, gate_transaction, get_ingredient_record, get_market_status, and 15 more. Their descriptions and schemas cost roughly 1,606 tokens of context every time the server is loaded.

### Does the A2A Cosmetics MCP server require authentication?

No. We connected to A2A Cosmetics without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the A2A Cosmetics MCP server still maintained?
