## 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__storefinch__get_place` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__storefinch__verify_websites` |
| 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 (2)

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

### `export_leads`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Build a lead list as a CSV download link (valid 24 h): name, category, address, phone, website,
        email, socials, coordinates, source and license per row. Needs a category and a location.
        Rows count against the plan's monthly export quota; preview shows the first rows.
```

### `verify_websites`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Check whether each place's listed website is live right now (status per place: live,
        live_bot_protected, redirected_elsewhere, page_not_found, dead_domain, unreachable, ...).
        Use before outreach. Each place checked counts as one call.
```

## Only reads (3)

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

### `find_categories`

- The name "find_categories" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find category ids to use with search_places / export_leads. Returns matching ids, their place
        in the taxonomy, and how many US places each has. Broader ids include all their subcategories.
```

### `get_place`

- The name "get_place" says "get": a word for reading.
- Tag private-data: The description's first sentence says "contact": it reads contacts.

Description, as the server wrote it:

```untrusted-server-text
Full record for one place: all contact fields, coordinates, category path, data sources and
        license, and the latest website check if one was run.
```

### `search_places`

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

Description, as the server wrote it:

```untrusted-server-text
Search US businesses and places by category, name and location. Needs at least one location
        filter or a name. Returns up to 100 compact results per call plus the total match count; use
        export_leads instead when you need more than a few pages.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__storefinch__find_categories",
      "mcp__storefinch__search_places",
      "mcp__storefinch__get_place"
    ],
    "ask": [
      "mcp__storefinch__export_leads",
      "mcp__storefinch__verify_websites"
    ],
    "deny": []
  }
}
```

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

- `mcp__storefinch__get_place`: private-data
- `mcp__storefinch__verify_websites`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-11-13T11:21:06.343Z, unchanged since 2026-11-13T11:21:06.343Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `401` |
| tools/list served without credentials | `no` |
| Tools that change things, listed without credentials | `0` |
| Protocol version | `none` |
| WWW-Authenticate on 401 | `yes` |
| resource_metadata in WWW-Authenticate | `https://storefinch.com/.well-known/oauth-protected-resource` |
| RFC 9728 protected resource metadata | `https://storefinch.com/.well-known/oauth-protected-resource` |
| Authorization servers | `https://storefinch.com` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `yes` |
| Client ID metadata documents | `no` |

Posture changes:

- 2026-11-13T11:21:06.343Z: HTTP status of an anonymous initialize `200` -> `401`; tools/list served without credentials `yes` -> `no`; Tools that change things, listed without credentials `2` -> `0`; Protocol version `2025-06-18` -> `none`; WWW-Authenticate on 401 `not observed` -> `yes`; resource_metadata in WWW-Authenticate `none` -> `https://storefinch.com/.well-known/oauth-protected-resource`; RFC 9728 protected resource metadata `none` -> `https://storefinch.com/.well-known/oauth-protected-resource`; Authorization servers `none` -> `https://storefinch.com`; Dynamic client registration `not observed` -> `yes`; Client ID metadata documents `not observed` -> `no`
