## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__leads__get_list_details` `mcp__leads__get_market_stats` `mcp__leads__search_lists` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__leads__get_list_details` `mcp__leads__get_market_stats` |
| 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 `request_custom_list` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "request_custom_list" says "request": a word for a change.
```


## Changes things (1)

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

### `request_custom_list`

- The name "request_custom_list" says "request": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
When no ready-made list fits (an unusual industry, a county or a radius, several industries together), return the link to request a custom list and its price. We measure the data and reply with the real count before any payment.
```

## Only reads (4)

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

### `get_list_details`

- The name "get_list_details" says "get": a word for reading.
- Tag private-data: The description's first sentence says "file": it reads files.
- Tag untrusted-input: The description's first sentence says "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Details of one list from search_lists: the fields included in the file, the price, the freshness policy, and a masked 5-row sample (business name, city, Google rating; emails and phones are masked). Pass the list value search_lists returned, or the list's publicleads.com URL.
```

### `get_market_stats`

- The name "get_market_stats" says "get": a word for reading.
- Tag private-data: The description's first sentence says "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Aggregate statistics for an industry in a place: number of operational businesses, average Google rating, total reviews, and the percentage with an email, with a company-domain email, with a phone, with a website and with a street address. No contact details. Use for market-sizing questions such as "how many plumbers are there in Ohio".
```

### `list_trades`

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

Description, as the server wrote it:

```untrusted-server-text
List every industry (trade) PublicLeads sells business lists for, with the slug to pass to search_lists, plus the countries covered (US, Canada, Australia). Call this when the user's industry may not match a name directly.
```

### `search_lists`

- The name "search_lists" says "search": a word for reading.
- Tag private-data: The description's first sentence says "find" and "contact": it reads contacts.

Description, as the server wrote it:

```untrusted-server-text
Find ready-made business contact lists for sale by industry and location. Returns up to 10 lists, best match first (the exact city, then its state/province, then the country): name, scope, number of businesses, how many have an email, price, and preview and buy links. Location can be a city ("Austin", "Austin, TX"), a state or province ("Ontario"), or a country ("USA", "Canada", "Australia"); spelling is matched loosely. Use when someone needs leads or prospects of a type of local business.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__leads__list_trades",
      "mcp__leads__search_lists",
      "mcp__leads__get_list_details",
      "mcp__leads__get_market_stats"
    ],
    "ask": [
      "mcp__leads__request_custom_list"
    ],
    "deny": []
  }
}
```

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

- `mcp__leads__search_lists`: private-data
- `mcp__leads__get_list_details`: private-data, untrusted-input
- `mcp__leads__get_market_stats`: private-data, untrusted-input
