## Exfil surface

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

| 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__advertiserleads__check_store` `mcp__advertiserleads__lookup_brand` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

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

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


## Changes things (1)

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

### `check_store`

- The name "check_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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Store platform (Shopify, WooCommerce, BigCommerce, other store or not a store), catalog size, price range and store age for a domain, plus the tracking pixels and marketing tools on its homepage (Meta, Google Ads, TikTok, Pinterest, Klaviyo, Triple Whale and more). Results under a day old are reused; fresh checks are limited per day (10 without signing in, 50 signed in).
```

## Only reads (3)

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

### `list_niches`

- The name "list_niches" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The niches AdvertiserLeads tracks, the signal types and filter values search_signals accepts, and what the caller's plan includes.
```

### `lookup_brand`

- The name "lookup_brand" says "lookup": a word for reading.
- 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
Is this store running Meta ads? Finds the Facebook page behind a store domain and returns advertising since, live ads, trend (new, scaling, stable, stopped), channels and store platform. Signed in: catalog size, price range, recent launches and store age (free plan: 5 new domains a day); Pro and up also get recent ads. Unknown domains are checked live in the Meta Ad Library, within a daily limit.
```

### `search_signals`

- The name "search_signals" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
US ecommerce brands flagged on the latest day for a change in their Meta (Facebook/Instagram) ads: newly advertising, scaling, struggling or stopped, with store platform, live ad count and other ad channels. Defaults to new and scaling brands in every niche the caller's plan covers. Without signing in or on the free plan, brand names and domains are masked and only the niche filter applies. On paid plans each brand returned counts toward the account's monthly export rows (the same brand again that month is free).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__advertiserleads__search_signals",
      "mcp__advertiserleads__lookup_brand",
      "mcp__advertiserleads__list_niches"
    ],
    "ask": [
      "mcp__advertiserleads__check_store"
    ],
    "deny": []
  }
}
```

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

- `mcp__advertiserleads__lookup_brand`: untrusted-input
- `mcp__advertiserleads__check_store`: untrusted-input
