## 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 2026-08-03.

- **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 4 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**: 76/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 514 tokens (~128/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 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.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

### `search_plans` (~191 tokens)

Search eSIM plans

Search the purchasable travel eSIM plan catalog. Filter by destination country, region, minimum data, minimum duration, and maximum price. Returns public plan details (prices in USD cents) sorted cheapest first, with offset pagination via next_offset.

Input parameters:

- `destination` (string): Country to cover: ISO-2 code (e.g. 'JP') or English name (e.g. 'Japan').
- `limit` (integer): Page size, 1-50 (default 20).
- `max_price_cents` (integer): Maximum retail price in USD cents.
- `min_data_bytes` (integer): Minimum total data allowance in bytes (unlimited plans always match).
- `min_duration_days` (integer): Minimum validity in days.
- `offset` (integer): Pagination offset from a previous next_offset.
- `region` (string): Region name filter, e.g. 'Europe' or 'Asia'.

### `get_plan` (~67 tokens)

Get one eSIM plan

Fetch full public details for a single purchasable plan by its package_code: coverage, data allowance, validity, retail price in USD cents. Errors with plan_not_found for unknown or unsellable codes.

Input parameters:

- `package_code` (string, required): The plan's package_code from search_plans.

### `check_availability` (~95 tokens)

Check plan availability

Check whether a plan can be fulfilled right now for a given quantity, using the same gate the checkout runs. Returns available true/false; reason 'delisted' means the SKU left the catalog, 'unavailable' means it temporarily cannot be fulfilled.

Input parameters:

- `package_code` (string, required): The plan's package_code from search_plans.
- `quantity` (integer): Units to buy (default 1, max 10).

### `get_quote` (~101 tokens)

Quote an order

Price an order (package_code, quantity, optional promo code) exactly as checkout would: returns subtotal, discount, and the final total in USD cents, plus the promo status. Purely informational — no order is created.

Input parameters:

- `package_code` (string, required): The plan's package_code from search_plans.
- `promo_code` (string): Optional promo code to apply.
- `quantity` (integer): Units to buy (default 1, max 10).
