## 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.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `scan_for_leaks`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Check text BEFORE your agent sends it to an LLM, tool, log or webhook: finds crypto wallet keys (BIP39 seed phrases with checksum, EVM/Solana private keys, WIF, xprv), API secrets (GitHub, AWS, Stripe, OpenAI, Anthropic, Slack, Telegram, npm, JWT, PEM) and PII (cards, IBAN, SSN, email, phone). Free preview tier: verdict, safe_to_send and counts by type (text up to 8192 bytes). Redacted text: paid x402 endpoint /v1/lite ($0.005); JSON payloads and live balances of wallets whose keys leaked: /v1/scan ($0.02).
```
