## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `verify_payment`

- The name "verify_payment" says "payment": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Submit tx_hash after paying an invoice. Supports XRPL, Xahau, Base (0x… hash), and Solana. Returns a signed JWT access_token (1-hour TTL). For a Xahau invoice with fee_required=true, also submit fee_tx_hash (the 0.01 XAH facilitator-fee payment) — settlement requires both payments. Free.
```

## Changes things (7)

Xahau invoices for third-party endpoints also return fee_required/fee_amount/fee_pay_to/fee_memo_hex: a flat 0.01 XAH facilitator fee paid as a second Xahau Payment (SML endpoints are fee-exempt; the XRPL rail has no facilitator fee). Free.
