Available components
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. How we score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability77
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 577 tokens (~115/item across 5 items; 5 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

create_checkout ~143
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.
| Name | Type | Req | Description |
|---|---|---|---|
| string | yes | Buyer's email — the eSIM QR code is also sent here. | |
| lang | string | — | Delivery email language (default 'en'). |
| sku_or_id | string | yes | The plan sku or id to buy. |
No output schema declared.
No examples provided.
get_esim_plan ~73
Get one ALT eSIM plan by its sku or id. Returns full details: title, data amount, validity days, USD price, coverage carriers, product URL.
| Name | Type | Req | Description |
|---|---|---|---|
| sku_or_id | string | yes | The plan sku (e.g. 'eSIM_Alt_JP_1DG1') or id. |
No output schema declared.
No examples provided.
get_qr_code ~141
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.
| Name | Type | Req | Description |
|---|---|---|---|
| checkout_session_id | string | yes | The checkout_session_id from create_checkout (Stripe session id). |
No output schema declared.
No examples provided.
