## 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 5 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**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 577 tokens (~115/item across 5 items; 5 tools + 0 resources), lean.
  - 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**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (5)

### `search_esim_plans` (~135 tokens)

Search ALT eSIM travel data plans. Filter by destination country slug (e.g. 'japan', 'usa', 'europe'), region, and/or max USD price. Returns plans with sku, data amount, validity days, USD price and coverage carriers. All prices are USD.

Input parameters:

- `country` (string): Destination country/region slug, e.g. 'japan', 'south-korea', 'thailand', 'usa', 'europe'. Omit to list all.
- `max_price_usd` (number): Optional max price in USD.
- `region` (string): Optional region filter.

### `list_destinations` (~43 tokens)

List all ALT eSIM destinations (country/region slugs with English names and region). Use a slug as the 'country' argument for search_esim_plans.

### `get_esim_plan` (~73 tokens)

Get one ALT eSIM plan by its sku or id. Returns full details: title, data amount, validity days, USD price, coverage carriers, product URL.

Input parameters:

- `sku_or_id` (string, required): The plan sku (e.g. 'eSIM_Alt_JP_1DG1') or id.

### `create_checkout` (~143 tokens)

Create a secure Stripe payment link for an ALT eSIM plan. Returns a payment URL the BUYER opens to pay (the agent never handles card details) AND a checkout_session_id. After the buyer pays, call get_qr_code with that checkout_session_id to fetch the eSIM QR and show it to the buyer. The QR is also emailed. Charged in USD. You MUST collect the buyer's real email.

Input parameters:

- `email` (string, required): Buyer's email — the eSIM QR code is also sent here.
- `lang` (string): Delivery email language (default 'en').
- `sku_or_id` (string, required): The plan sku or id to buy.

### `get_qr_code` (~141 tokens)

Fetch the eSIM QR code(s) for an order, to show the buyer directly. Pass the checkout_session_id from create_checkout. Returns a clear `status`: 'awaiting_payment' (buyer has NOT paid — tell them to pay), 'processing' (paid, eSIM still provisioning — retry in ~30s), 'ready' (returns the QR image(s) + ICCID(s) to display), 'expired', 'refunded', or 'failed'. Use the status to tell the buyer exactly what's happening — never assume payment succeeded.

Input parameters:

- `checkout_session_id` (string, required): The checkout_session_id from create_checkout (Stripe session id).
