## 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**: 63/100
  - 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 check failed: the endpoint is reachable over plaintext HTTP.
  - 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**: 78/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 355 tokens (~118/item across 3 items; 3 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**: 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-05 (score 67, +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.

### 2026-11-04 (score 66, 0)

## MCP tools (3)

### `esim_find_plans` (~130 tokens)

Find NUM data eSIM plans for a country, city, airport code or region, with one recommended plan for the trip. Read only. Prices are in US dollars. Plans are data only, with no phone number.

Input parameters:

- `days` (integer): Length of the trip in days. Defaults to 14.
- `destination` (string, required): A country, city, airport code or region, such as Japan, Bali, BKK or Europe.
- `use` (string): How the phone will be used. light: maps and messages. regular: social and photos. heavy: video and hotspot.

### `esim_start_checkout` (~92 tokens)

Start an order for a plan from esim_find_plans and get a checkout link for the person. Nothing is charged here. The person must open the link, confirm their phone number in NUM, and pay on Stripe themselves. Ask the person before calling this.

Input parameters:

- `destination` (string, required): The same destination used to find the plan.
- `plan_id` (string, required): A plan id from esim_find_plans.

### `esim_order_status` (~54 tokens)

Check an order started with esim_start_checkout: waiting for verification, waiting for payment, paid, or ready in NUM. Never returns an install code.

Input parameters:

- `order_ref` (string, required): The order_ref from esim_start_checkout.
