## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__tokenverdict__check_token` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Base64 strings in `check_token` ([base64-blob](https://anlyon.dev/methodology#base64-blob))

```untrusted-server-text
The input schema at properties.token.description contains a 42-character base64 string.

inputSchema.properties.token.description: "...tract address, e.g. 0x532f27101965dd16442E59d40670FaF5eBB142E4"
```


## Changes things (1)

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

### `check_token`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Safety verdict for a Base (chain 8453) ERC-20 token: SAFE / CAUTION / DANGER with a 0-100 score, from a simulated buy-transfer-sell (honeypot and tax detection), owner powers, proxy, liquidity, holders, verification and age. Free preview tier: verdict, score and flag counts. The paid x402 endpoints /v1/lite ($0.005), /v1/quick ($0.015) and /v1/deep ($0.05) add the reasons and evidence. Informational, not financial advice.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `tokenverdict`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__tokenverdict__check_token"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__tokenverdict__check_token`: untrusted-input
