- Actively maintained (last published 63 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability74
- AI-judged instruction clarity (excellent).Pass

Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
esim_check_order ~77
Poll an order's status. Returns `status: pending` while waiting for payment, `status: processing` or `completed` once paid, with `activation` data (ICCID, QR URL, install instructions).
| Name | Type | Req | Description |
|---|---|---|---|
| order_id | number | yes | – |
| order_token | string | yes | The opaque token returned by esim_create_order. |
No output schema declared.
No examples provided.
esim_create_order ~309
Create a pending order. With `payment_method: "stripe"` (default) you get back a `payment_link_url` — present it to the user to tap and pay on Stripe's hosted page. With `payment_method: "btc"` you get back a `btc` block (on-chain address + amount + QR data URI + expiry) — present the address and amount to the user to pay from any Bitcoin wallet; no redirect. If the user hasn't said how they want to pay, ask: card or Bitcoin. The eSIM QR code arrives at `email` within ~30 seconds of payment clearing. Use `esim_check_order` to poll status.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_source | string | – | Optional: identifier for the calling agent (e.g. 'claude-code', 'cursor'). Used for our analytics; not seen by the buyer. |
| string | yes | Buyer's email address. The eSIM QR code will be delivered here. | |
| payment_method | string | – | How the buyer pays. 'stripe' (default) → hosted card checkout, returns a payment_link_url. 'btc' → on-chain Bitcoin, returns a btc block (address + sats + QR) to show the user directly. BTC may be de… |
| variation_id | number | yes | The specific variation ID to buy (from esim_search_plans or esim_get_plan). |
No output schema declared.

|---|---|---|---|
| slug | string | yes | Plan slug, e.g. 'spain' or 'europe'. |
No output schema declared.
No examples provided.
esim_search_plans ~240
Search the Worldcitisim eSIM catalog. Returns plans matching the given filters (country ISO code, region, desired days, desired GB). Plans have variations — each variation is one specific (days × GB × price) combo. The user picks one variation_id to buy.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | – | Two-letter ISO 3166-1 alpha-2 country code (e.g. 'JP', 'ES', 'US') OR a plan slug ('spain', 'japan', 'europe', 'global'). Matched case-insensitively against plan slugs and display names. |
| limit | number | – | Max plans to return (default 5, max 20). |
| max_days | number | – | Maximum plan duration in days. |
| min_days | number | – | Minimum plan duration in days. |
| min_gb | number | – | Minimum data allowance in GB. Use -1 for 'unlimited'. |
