## 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_xrp_payment`

- The name "verify_xrp_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 an XRP transaction hash for FDC attestation on Flare. Subscription API keys inside quota are not charged extra. Without a key, or over quota, the tool returns an x402 payment challenge (XRP or RLUSD via the XRPL facilitator). A valid PAYMENT-SIGNATURE pays for exactly one attestation. Status checks are free. Proof takes ~90-180 seconds; use get_attestation_status.
```

## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `get_attestation_by_round`

- The name "get_attestation_by_round" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List all attestations for a given FDC voting round ID.
```

### `get_attestation_status`

- The name "get_attestation_status" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the current status of an attestation by its UUID. Call this after verify_xrp_payment to check if the proof is ready and verified on-chain.
```

### `get_server_info`

- The name "get_server_info" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get XRPLink server information, network details, contract addresses, and white-label branding.
```

### `lookup_attestation_by_tx`

- The name "lookup_attestation_by_tx" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up an attestation by its original XRP transaction hash. Returns the full attestation record if one exists.
```
