## 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__rankroot__audit_ai_visibility` `mcp__rankroot__check_ai_crawler_access` `mcp__rankroot__generate_ai_visibility_files` `mcp__rankroot__validate_llms_txt` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__rankroot__audit_ai_visibility` `mcp__rankroot__check_ai_crawler_access` `mcp__rankroot__generate_ai_visibility_files` `mcp__rankroot__validate_llms_txt` |

## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "generate_ai_visibility_files" says "generate": a word for a change.
```


## Changes things (3)

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

### `audit_ai_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.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Score how discoverable a website is by AI answer engines (ChatGPT, Perplexity, Claude, Google AI Overviews) and AI agents. Returns a 0-100 score, per-category scores and a prioritized fix list.
```

### `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.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Check which AI crawlers (OAI-SearchBot, ChatGPT-User, GPTBot, ClaudeBot, Claude-SearchBot, PerplexityBot, Google-Extended and more) a site's robots.txt and firewall/CDN let in. Flags blocked AI search bots, which cost citations.
```

### `generate_ai_visibility_files`

- The name "generate_ai_visibility_files" says "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 ready-to-publish llms.txt, an AI-bot-friendly robots.txt and schema.org JSON-LD for a website, based on its current homepage.
```

## Only reads (3)

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

### `get_checkout_link`

- The name "get_checkout_link" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the Polar checkout link for one RankRoot plan, to hand to the user. The user pays on Polar and receives a license key by email; pass it as 'Authorization: Bearer <key>' for higher API/MCP limits. If checkoutOpen is false, the link is an application form the user fills in instead.
```

### `get_pricing`

- The name "get_pricing" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List RankRoot plans (free scan, Fix Pack one-time, done-for-you AI Visibility Employee monthly) with prices, limits, checkout links and which plan fits which user. Agents cannot pay: give the user the checkout link.
```

### `validate_llms_txt`

- The name "validate_llms_txt" says "validate": a word for reading.
- 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.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Fetch a site's llms.txt (pass the site URL, or a URL ending in /llms.txt or /llms-full.txt for a subpath file) and check it against the llmstxt.org format: H1, summary, H2 link lists, Optional section.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__rankroot__get_pricing",
      "mcp__rankroot__get_checkout_link"
    ],
    "ask": [
      "mcp__rankroot__audit_ai_visibility",
      "mcp__rankroot__generate_ai_visibility_files",
      "mcp__rankroot__check_ai_crawler_access",
      "mcp__rankroot__validate_llms_txt"
    ],
    "deny": []
  }
}
```

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

- `mcp__rankroot__audit_ai_visibility`: untrusted-input, outbound
- `mcp__rankroot__generate_ai_visibility_files`: untrusted-input, outbound
- `mcp__rankroot__check_ai_crawler_access`: untrusted-input, outbound
- `mcp__rankroot__validate_llms_txt`: 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 8 tools that change things (8 write). Whether a call also works without credentials was not tested: tools are never called.

https://getrankroot.com/api/mcp: tools/list returned 12 tools to an anonymous client, including audit_ai_visibility (write), generate_ai_visibility_files (write), check_ai_crawler_access (write), amplify_preview (write), amplify_create_campaign (write) and 3 more
