## 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__ai-crawler-check__check_ai_crawler_access` |
| 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.

### `check_ai_crawler_access`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Checks whether AI crawlers can reach and read a public website or web app: which AI crawlers (GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot, Google-Extended and more) robots.txt allows and the exact rule for each, how much text the homepage HTML carries for crawlers that do not run JavaScript (flags client-rendered app shells, common in apps built with Lovable, Bolt, Base44 or Replit), title/meta description/H1, llms.txt, sitemap, and the platform or host setting to change (Cloudflare, Vercel, Netlify). Use it when someone asks why their site or app does not show up in ChatGPT, Claude, Perplexity or other AI answers.
```

## Only reads (1)

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

### `list_ai_crawlers`

- The name "list_ai_crawlers" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists the AI crawler user-agent tokens Atalaya checks, by vendor and purpose (training, search index, user-triggered fetch), so you can write a robots.txt that keeps AI search while opting out of training.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `ai-crawler-check`:

```json
{
  "permissions": {
    "allow": [
      "mcp__ai-crawler-check__list_ai_crawlers"
    ],
    "ask": [
      "mcp__ai-crawler-check__check_ai_crawler_access"
    ],
    "deny": []
  }
}
```

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

- `mcp__ai-crawler-check__check_ai_crawler_access`: untrusted-input
