## 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__lists__count_homes` `mcp__lists__preview_market` `mcp__lists__start_checkout` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `start_checkout`

- The name "start_checkout" says "start": a word for a change.
- 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
Start buying a mailing list of the matching homes: owner names and mailing addresses delivered as an Excel file plus a CSV. Returns a Stripe Checkout URL; the user opens it and pays there (this tool never handles card details). Minimum 1000 addresses ($349). Needs a Meadley Bros. API key. Members create keys in Profile and billing under Advanced integrations. Only call this when the user has clearly asked to buy.
```

## Only reads (2)

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

### `count_homes`

- The name "count_homes" says "count": 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
How many households in a service area fit a contractor's trade, judged from property signals (tree canopy, slope, lot size, pool) rather than just addresses. Free, no key needed. Returns the count, the price to buy, and a link where the user can buy the list in one step.
```

### `preview_market`

- The name "preview_market" says "preview": 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
The measured count for a trade and area, plus every strategy card the trade offers (id, name, whether it is the widest) so the user can narrow by sending strategyIds, and which property signals are measured there. Needs a Meadley Bros. API key. Members create keys in Profile and billing under Advanced integrations.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__lists__count_homes",
      "mcp__lists__preview_market"
    ],
    "ask": [
      "mcp__lists__start_checkout"
    ],
    "deny": []
  }
}
```

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

- `mcp__lists__count_homes`: untrusted-input
- `mcp__lists__preview_market`: untrusted-input
- `mcp__lists__start_checkout`: untrusted-input
