## 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__site-check__check_ai_built_app` `mcp__site-check__check_site_email_security` `mcp__site-check__diagnose_shopify_store` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__site-check__check_ai_built_app` `mcp__site-check__check_site_email_security` `mcp__site-check__diagnose_shopify_store` |

## Findings

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

```untrusted-server-text
The server marks "diagnose_shopify_store" 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 "diagnose_shopify_store" says "store": a word for a change.
```


## Changes things (2)

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

### `check_site_email_security`

- 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 a domain's email is likely to reach the inbox (SPF, DKIM and DMARC records, mail servers) and whether the website has basic security in place (HTTPS, security headers, WordPress exposure, Lovable/Supabase setup). Reads only public DNS records and the public home page. The report is written in Portuguese.
```

### `diagnose_shopify_store`

- The name "diagnose_shopify_store" says "store": 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
Reads the public pages of a Shopify store and reports whether it offers social login and a wishlist, how many products show as sold out, and whether it runs storefronts for several countries. Reads only public pages.
```

## Only reads (1)

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

### `check_ai_built_app`

- The description's first verb is "read": 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 "read" and "web": 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
Reads the public pages and public JavaScript of a web app (typically built with Lovable, Bolt, v0, Replit or similar) and reports exposed API keys, public source maps, missing security headers, stale deploys, missing error monitoring and AI model calls made from the browser. Passive check: it never logs in, submits forms or probes private routes.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__site-check__check_site_email_security",
      "mcp__site-check__check_ai_built_app",
      "mcp__site-check__diagnose_shopify_store"
    ],
    "deny": []
  }
}
```

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

- `mcp__site-check__check_site_email_security`: untrusted-input, outbound
- `mcp__site-check__check_ai_built_app`: untrusted-input, outbound
- `mcp__site-check__diagnose_shopify_store`: untrusted-input, outbound
