## 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__aeo-visibility__analyze_website_aeo` `mcp__aeo-visibility__check_ai_visibility` `mcp__aeo-visibility__compare_competitor_visibility` `mcp__aeo-visibility__discover_ranking_prompts` `mcp__aeo-visibility__get_visibility_report` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__aeo-visibility__analyze_website_aeo` `mcp__aeo-visibility__check_ai_visibility` `mcp__aeo-visibility__compare_competitor_visibility` `mcp__aeo-visibility__discover_ranking_prompts` `mcp__aeo-visibility__get_visibility_report` |

## Findings

- **warn** Annotations that disagree with the tool in `discover_ranking_prompts` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "discover_ranking_prompts" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The description's first verb is "generate": a word for a change.
```

- **warn** Annotations that disagree with the tool in `compare_competitor_visibility` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "compare_competitor_visibility" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "compare_competitor_visibility" says "compare": a word for reading.
```


## Changes things (2)

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

### `compare_competitor_visibility`

- The name "compare_competitor_visibility" says "compare": a word for reading.
- The description's first verb is "run": a word for a change.
- 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. 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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Run one Perplexity Sonar query and rank several competitor URLs by whether and where each is cited for the prompt.
```

### `discover_ranking_prompts`

- The description's first verb is "generate": a word for a change.
- 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.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Generate realistic user prompts a site should aim to be cited for on a topic, using Perplexity Sonar. Optionally tests a few of them for live visibility.
```

## Only reads (3)

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

### `analyze_website_aeo`

- The name "analyze_website_aeo" says "analyze": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The name "analyze_website_aeo" says "analyze" and "website": it reads web pages, which anyone can write. The description's first sentence says "crawl": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): 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
Crawl a URL, parse its HTML and structured data, and score it for answer-engine optimization (AEO). Returns an AEO-focused summary, AI-bot access, and crawl-hint files.
```

### `check_ai_visibility`

- The description's first verb is "query": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "query" and "url": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): 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
Query Perplexity Sonar with a prompt and inspect its citations to determine whether the given URL is cited as a source, and at what rank.
```

### `get_visibility_report`

- The name "get_visibility_report" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "url": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): 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
Combine an AEO audit of a URL with per-prompt AI-visibility checks into a single report with an overall citation rate.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__aeo-visibility__analyze_website_aeo",
      "mcp__aeo-visibility__check_ai_visibility",
      "mcp__aeo-visibility__discover_ranking_prompts",
      "mcp__aeo-visibility__get_visibility_report",
      "mcp__aeo-visibility__compare_competitor_visibility"
    ],
    "deny": []
  }
}
```

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

- `mcp__aeo-visibility__analyze_website_aeo`: untrusted-input, outbound
- `mcp__aeo-visibility__check_ai_visibility`: untrusted-input, outbound
- `mcp__aeo-visibility__discover_ranking_prompts`: untrusted-input, outbound
- `mcp__aeo-visibility__get_visibility_report`: untrusted-input, outbound
- `mcp__aeo-visibility__compare_competitor_visibility`: untrusted-input, outbound
