| --- | --- | --- |
| 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__credits__credits_quote` |
| 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.


## Only reads (2)

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

### `credits_balance`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the remaining balance, spend and recent calls of a YourAITools credits key (yatc_...).
```

### `credits_quote`

- The description's first verb is "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "list" and "web": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Lists how many calls of each YourAITools paid API (PayGuard, TokenVerdict, SignCheck, WebRead, InjectScan, DomainCheck, PkgGuard, StackDetect, AgentGate) a $1 or $5 prepaid credits pack covers at today's prices, and where to buy it (x402).
```

## Claude Code permissions

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

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

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