## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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.

### `asp_recommend_panels`

- 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
See how many Acoustic Sound Panels to plan for in a room and what they cost today. Give the room's length, width and ceiling height in feet and what the room is used for. Returns a starting panel size and count, the estimated echo before and after, exact current prices from the store when they are available, the shipping statement that applies, and a link to the product page. Panels are priced as Burch Fabrics Prime Time, and other fabrics show their own exact prices on the product page.
```

### `asp_start_free_room_analysis`

- The name "asp_start_free_room_analysis" says "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Ask the Acoustic Sound Panels team for a Free Room Analysis: a recommended layout and one written quote for the room. Before calling, ask the person for their first name, email address and ZIP code, and get a clear yes to sharing them with Acoustic Sound Panels for this request. Nothing is ordered or charged. Returns a confirmation and, for a new request, a personal link for adding photos, room dimensions or a short video.
```

## Only reads (2)

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

### `asp_calculate_room_acoustics`

- The description's first verb is "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find out how much echo a room is likely to have and how much of its walls and ceiling is worth covering. Give the room's length, width and ceiling height in feet and what the room is used for. Returns an estimated echo time in seconds with a plain rating for speech, and the share of walls and ceiling Acoustic Sound Panels suggests covering as a starting point. These are estimates for planning, based on a plain rectangular room. A Free Room Analysis gives the team's recommended layout.
```

### `asp_get_scan_link`

- The name "asp_get_scan_link" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get a way to capture a room for Acoustic Sound Panels: the Acoustic Sound Panels app for iPhone Pro and iPad Pro models with LiDAR. A personal link for sending photos, room dimensions or video comes with a Free Room Analysis request.
```

## Claude Code permissions

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.acousticsoundpanels.com: tools/list returned 4 tools to an anonymous client, including asp_recommend_panels (write), asp_start_free_room_analysis (write)
