## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| 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__seo-tools__ai-answer-change-alert` `mcp__seo-tools__ai-crawler-access-checker` `mcp__seo-tools__ai-overview-tracker` `mcp__seo-tools__llm-brand-visibility` `mcp__seo-tools__llms-txt-auditor` `mcp__seo-tools__social-preview-checker` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__seo-tools__social-preview-checker` |

## Findings

No check matched anything in these tool definitions.


## Changes things (6)

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

### `ai-answer-change-alert`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Ask an LLM the queries that matter to you, compare each answer against its stored baseline and get told what changed — the answer itself and which domains it now cites or stopped citing. One row per query x model. — $0.10/call, x402 (USDC on base).
```

### `ai-crawler-access-checker`

- 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
Check which AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended & more) can access your website. Bulk audit of robots.txt rules, llms.txt presence and sitemap for AI search visibility (GEO/AEO). — $0.01/call, x402 (USDC on base).
```

### `ai-overview-tracker`

- 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
For each query that matters, see which sources and domains AI assistants cite in their answer — grounded via Perplexity Sonar, GPT or Gemini through your own OpenRouter key. GEO citation tracking: the backlink profile of the AI-answer era. — $0.10/call, x402 (USDC on base).
```

### `llm-brand-visibility`

- 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
For each query that matters, check whether AI assistants recommend YOUR brand — and which competitors they cite instead. Grounded answers from Perplexity Sonar, GPT and Gemini via your own OpenRouter key. This is GEO: the SEO of the AI era. — $0.10/call, x402 (USDC on base).
```

### `llms-txt-auditor`

- 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
Give it a domain. It checks whether the site publishes a valid llms.txt / llms-full.txt (the emerging AI-crawler-friendly-docs convention) and whether robots.txt blocks GPTBot, ClaudeBot, Google-Extended, PerplexityBot and 5 other AI crawlers. llms.txt-first, no browser, no LLM, no API key. — $0.01/call, x402 (USDC on base).
```

### `pricing_info`

- 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
Free — list every paid tool in the 'seo-tools' bundle with its price, payTo address and network. Call this first if you don't have a wallet ready yet.
```

## Only reads (1)

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

### `social-preview-checker`

- The name "social-preview-checker" says "preview": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The input takes a URL (input.urls), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.urls): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
See exactly how your links look when shared on Telegram, WhatsApp, X, LinkedIn, Slack, Facebook & Discord. Bulk-audit Open Graph and Twitter Card tags, validate preview images, and find what breaks your link previews. — $0.01/call, x402 (USDC on base).
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `seo-tools`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__seo-tools__pricing_info",
      "mcp__seo-tools__ai-answer-change-alert",
      "mcp__seo-tools__ai-crawler-access-checker",
      "mcp__seo-tools__ai-overview-tracker",
      "mcp__seo-tools__llm-brand-visibility",
      "mcp__seo-tools__llms-txt-auditor",
      "mcp__seo-tools__social-preview-checker"
    ],
    "deny": []
  }
}
```

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

- `mcp__seo-tools__ai-answer-change-alert`: untrusted-input
- `mcp__seo-tools__ai-crawler-access-checker`: untrusted-input
- `mcp__seo-tools__ai-overview-tracker`: untrusted-input
- `mcp__seo-tools__llm-brand-visibility`: untrusted-input
- `mcp__seo-tools__llms-txt-auditor`: untrusted-input
- `mcp__seo-tools__social-preview-checker`: untrusted-input, outbound

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 6 tools that change things (6 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.timzinin.com/mcp/seo-tools: tools/list returned 7 tools to an anonymous client, including pricing_info (write), ai-answer-change-alert (write), ai-crawler-access-checker (write), ai-overview-tracker (write), llm-brand-visibility (write) and 1 more
