## 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__free-aeo-tools__check_ai_crawler_access` `mcp__free-aeo-tools__check_structured_data` `mcp__free-aeo-tools__generate_llms_txt` `mcp__free-aeo-tools__run_aeo_audit` `mcp__free-aeo-tools__score_answer_readiness` `mcp__free-aeo-tools__validate_llms_txt` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__free-aeo-tools__check_ai_crawler_access` `mcp__free-aeo-tools__check_structured_data` `mcp__free-aeo-tools__generate_llms_txt` `mcp__free-aeo-tools__run_aeo_audit` `mcp__free-aeo-tools__score_answer_readiness` `mcp__free-aeo-tools__validate_llms_txt` |

## Findings

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

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

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

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

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

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":true}; The name "run_aeo_audit" says "run": a word for a change.
```


## Changes things (5)

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.
- 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
Checks whether the crawlers behind ChatGPT, Claude, Perplexity, Google AI Overviews, Copilot and 14 more may read a page: robots.txt rules (RFC 9309), robots meta and X-Robots-Tag directives, and whether the site's firewall refuses each crawler's user agent. Separates search and user crawlers (which decide whether you can be cited) from training crawlers (which do not). Free, no key. Docs: https://aeolookup.com/aeo-tools/ai-crawler-checker/
```

### `check_structured_data`

- 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
Extracts every JSON-LD block on a page, lists the schema.org types it describes, flags missing required and recommended properties (Organization, LocalBusiness, Article, FAQPage, Product, Service, Person, BreadcrumbList, Event) and scores entity signals: a named organisation, sameAs links to other profiles, a logo and an @id. Free, no key. Docs: https://aeolookup.com/aeo-tools/schema-checker/
```

### `generate_llms_txt`

- The name "generate_llms_txt" 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
Drafts an llms.txt for a site: the name and summary from its home page, then its pages from the sitemap grouped by section, with titles and descriptions read from up to 24 pages. Returns the file as text, for a person to edit before publishing. Free, no key. Docs: https://aeolookup.com/aeo-tools/llms-txt-validator/
```

### `run_aeo_audit`

- The name "run_aeo_audit" says "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.
- 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
Runs all four checks on one address (AI crawler access, structured data, llms.txt, answer readiness) and returns each result plus an overall score: the mean of the crawler, schema and answer-readiness scores. llms.txt is reported but not scored, because the evidence says few systems read it. Free, no key. Docs: https://aeolookup.com/aeo-tools/api/
```

### `score_answer_readiness`

- 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
Scores a page out of 100 on 14 published checks: indexable, title and description, one H1, question headings, direct first-sentence answers, structured data, dates, a named author, lists and tables, source links, specific figures, length, declared language and stock AI phrasing. Returns each check's points, what it found and the fix, ordered by points available. Free, no key. Docs: https://aeolookup.com/aeo-tools/answer-readiness-checker/
```

## Only reads (1)

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

### `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
Fetches /llms.txt (or the llms.txt address given), validates it against the llmstxt.org proposal (one H1, optional summary, H2 sections of [name](url): notes links), tests up to eight of its links and reports whether llms-full.txt exists. States the evidence on how little the file is read. Free, no key. Docs: https://aeolookup.com/aeo-tools/llms-txt-validator/
```

## Claude Code permissions

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

```json

      "mcp__free-aeo-tools__run_aeo_audit"
    ],
    "deny": []
