## 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 11 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 1083 tokens (~98/item across 11 items; 11 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability check failed: schema churn in the 8 days we've observed: 2 tool removals, 0 breaking changes, 0 auth/transport breaks, 0 additions.
- **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 (11)

### `search_esim_plans` (~117 tokens)

Search BuyUKeSIM travel/data eSIM plans for a country. Returns plan name, data amount, validity days, USD price, and package code. Pass a 2-letter ISO country code (e.g. GB, US, TR, JP). Omit country to get popular/featured plans.

Input parameters:

- `country` (string): 2-letter ISO country code, e.g. GB, US, TR, JP. Optional.
- `limit` (integer): Max plans to return (1-50). Default 20.

### `list_covered_countries` (~40 tokens)

List the countries/regions BuyUKeSIM travel eSIM data plans currently cover, with how many plans each has (2-letter ISO codes).

### `get_uk_number_info` (~70 tokens)

Get details of the BuyUKeSIM UK Number (+44) eSIM: a real UK mobile line for unlimited incoming SMS and calls (app verification, banking, WhatsApp/Telegram), no KYC, paid in crypto, instant QR. This is distinct from the travel data eSIM.

### `check_order_status` (~72 tokens)

Look up the status of a BuyUKeSIM order using its short lookup/magic code (the code the customer received). Returns only the order status - no personal data, no QR.

Input parameters:

- `code` (string, required): The order lookup / magic code, e.g. 8U6D-ANCM.

### `create_wallet` (~107 tokens)

Create a new BuyUKeSIM agent wallet - a prepaid, no-KYC balance an AI agent funds with crypto and spends on eSIMs. Returns an api_key (ak_live_...) and a wallet_code. Save both: pass the api_key as a Bearer token to use the wallet; the wallet_code lets a human sign back in. Balance can only be spent on eSIMs, never withdrawn.

Input parameters:

- `label` (string): Optional short label to recognise this wallet later.

### `check_balance` (~34 tokens)

Check the balance of the agent wallet (requires the ak_live_ api key as a Bearer token). Returns available USD balance.

### `create_deposit` (~103 tokens)

Top up the agent wallet with crypto (requires the ak_live_ api key). Returns a crypto payment address and amount; the balance is credited automatically once the payment confirms on-chain. Minimum $10.

Input parameters:

- `amount_usd` (number, required): USD amount to add, minimum 10.
- `coin` (string): Payment method id, e.g. usdttrc20 (default), btc, eth, trx. See payment options on buyukesim.com.

### `list_transactions` (~33 tokens)

List the most recent transactions (deposits and purchases) on the agent wallet. Requires the ak_live_ api key.

### `purchase_esim` (~141 tokens)

Buy a travel/data eSIM using the agent wallet balance (requires the ak_live_ api key). Deducts the plan price from the balance and returns the eSIM QR code instantly. Get a package_code from search_esim_plans first. Pass a stable request_id to make retries safe (no double charge). This provisions a real eSIM - only call it when the user has confirmed the purchase.

Input parameters:

- `package_code` (string, required): The plan code from search_esim_plans, e.g. CKH253.
- `request_id` (string): Optional idempotency key - reuse the same value on a retry to avoid a double charge.

### `purchase_uk_number` (~105 tokens)

Buy a UK +44 Number eSIM (a real UK mobile line for incoming verification SMS and calls) using the agent wallet balance. Deducts about $25 and delivers a QR from stock instantly. Requires the ak_live_ api key. Pass request_id for safe retries. This delivers a real eSIM - only call it once the user has confirmed.

Input parameters:

- `request_id` (string): Optional idempotency key - reuse on a retry to avoid a double charge.

### `get_one_time_code` (~85 tokens)

Poll a purchased One-Time Code order for its SMS code. Returns the phone number and, once it arrives, the verification code. Call repeatedly (every few seconds) until phase is code_ready or failed. Requires the ak_live_ api key and the order_id from purchase_one_time_code.

Input parameters:

- `order_id` (integer, required): The order_id returned by purchase_one_time_code.
