## 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**: 80/100
  - 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.
  - 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**: 69/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 582 tokens (~194/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 33/100
  - Stability observed for 10 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**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (3)

### `search_esim_plans` (~272 tokens)

Search travel eSIM plans

Find the cheapest travel eSIM data plans for a destination from 25 providers (Airalo, Holafly, Nomad eSIM, Saily, Ubigi, Yesim and more), filtered to what a trip needs. Returns plans sorted by price (cheapest first) with data allowance, validity, price, price per GB, local network, speed policy, the date the price was checked, a page on eSIMCompare that cites the source, and a buy link. Buy links marked affiliate_link may earn eSIMCompare a commission; the price is the provider's own either way, and where a buy link applies a reader discount the plan also gives price_through_buy_url_usd.

Input parameters:

- `destination` (string, required): Country or region, by name or ISO code: 'Japan', 'JP', 'United States', 'Europe', 'Global'.
- `limit` (integer): How many plans to return (default 5).
- `max_price_usd` (number): Highest total price in US dollars.
- `min_data_gb` (number): Least data the trip needs, in GB. Unlimited plans always qualify.
- `trip_days` (integer): Trip length in days: plans must stay valid at least this long.
- `unlimited_only` (boolean): Only unlimited-data plans.

### `esim_price_index` (~121 tokens)

Travel eSIM price index

What a week of mobile data costs a traveler: the cheapest eSIM with at least 5 GB valid for at least 7 days, per country, from eSIMCompare's price index of 197 countries. With a country: its price, the plan behind it, the cheapest price per GB, the cheapest unlimited week and its rank among all countries. Without one: the median, the cheapest and dearest countries, and which providers are cheapest most often.

Input parameters:

- `country` (string): Country name or ISO code. Omit for the global summary.

### `compare_esim_providers` (~100 tokens)

Compare travel eSIM providers

How travel eSIM providers stand against each other on eSIMCompare's data: plans and destinations covered, entry price, best price per GB, share of unlimited plans, an independent verdict, and links to the full review and head-to-head pages. Pass one to four providers, or none for all of them.

Input parameters:

- `providers` (array): Provider names, such as ['Airalo', 'Holafly']. Omit for every provider.
