## 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__roomproof__read_product` |
| 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 (6)

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

### `check_plan`

- 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
Re-checks the saved layout only: pieces sticking out, overlaps, blocked areas including door swings, and a 0.9 m path to every piece. Does not place, move or spend a wish. Call it after move_furniture or when issues are unclear; ok true with an empty issues list is the condition for open_plan. Needs key on your own project, free on beispiel-wohnzimmer.
```

### `create_room`

- The name "create_room" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Free, no key. Creates a new plan at scale 1:50 and returns its project id plus purchase_url. Send name, plus either width_m and depth_m (rectangle) or rectangles (L-shape, alcove, bay), never both. Always send openings in this same call; without openings the checker treats the room as having no doors and skips the door-swing check. Each side 0.3 to 200 m. Coordinates: x to the right, y down, origin at the room's top-left corner.
```

### `move_furniture`

- The name "move_furniture" says "move": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Moves, rotates or removes one piece in the saved layout and returns the re-checked plan as an image with issues. Send x and y together (piece center, meters), rot, or remove true. The result is saved even with issues, so read them and move again if needed. Needs key on your own project, free on beispiel-wohnzimmer (not saved).
```

### `open_plan`

- The name "open_plan" says "open": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call only after the last check_plan returned no issues. Returns view_url (read-only, to share) and edit_url (for the owner, with the scaled PDF download). Needs key; not available on beispiel-wohnzimmer.
```

### `place_furniture`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Places furniture and returns the checked plan as an image plus placed, rejected, issues and image_prompt. Send exactly one of spots, placement, or wish. Prefer spots: you name each piece and a rough position (at), the server finds the exact spot, snaps to a 5 cm grid and avoids walls, doors and other pieces. Use placement only when the user gives exact positions; never invent x, y or rot. Use wish only when the user describes the room without naming pieces; it calls Roomproof's own model, is slower and less predictable. Every way is checked against the floor area, overlaps, blocked areas and a 0.9 m path; what does not fit comes back in rejected with a reason. Dimensions in millimeters; x and y in meters to the CENTER of the piece, from the room's top-left corner. Needs key on your own project, free on beispiel-wohnzimmer (nothing is saved there).
```

### `set_door`

- The name "set_door" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Replaces the full openings list of a project you created (an empty list removes all). Windows have no hinge. Until openings exist, door-swing clearance is not checked. Saved layouts may get new issues afterwards; run check_plan. Needs key; not available on beispiel-wohnzimmer.
```

## Only reads (3)

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

### `read_product`

- The name "read_product" says "read": 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
Free, no key. Turns a product link (IKEA, any furniture shop) or the pasted text of a product page into real dimensions: name, width_mm, depth_mm, height_mm, price, link. Call it as soon as the user gives a furniture link. On success pass name, width_mm, depth_mm, height_mm, price and link unchanged into a custom piece in place_furniture. If blocked is true, ask the user to paste the product page text and call read_product again with that text as input. Never guess millimeters; a missing dimension is listed in missing.
```

### `show_catalog`

- The name "show_catalog" says "show": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free, no key. Lists every piece Roomproof knows: catalog id (ASCII slug, copy it exactly), display name, width_mm, depth_mm, group. Call it with no group first. Custom pieces (name plus width_mm and depth_mm, e.g. from read_product) do not need the catalog.
```

### `show_plan`

- The name "show_plan" says "show": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the saved plan as an image drawn to scale, plus image_prompt and image_positions. For a photo of the room copy image_prompt verbatim into your own image generator; Roomproof does not render photos. Needs key on your own project, free on beispiel-wohnzimmer.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__roomproof__read_product",
      "mcp__roomproof__show_catalog",
      "mcp__roomproof__show_plan"
    ],
    "ask": [
      "mcp__roomproof__create_room",
      "mcp__roomproof__place_furniture",
      "mcp__roomproof__set_door",
      "mcp__roomproof__move_furniture",
      "mcp__roomproof__check_plan",
      "mcp__roomproof__open_plan"
    ],
    "deny": []
  }
}
```

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

- `mcp__roomproof__read_product`: untrusted-input

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 6 tools that change things (6 write). Whether a call also works without credentials was not tested: tools are never called.

https://getroomproof.com/mcp: tools/list returned 9 tools to an anonymous client, including create_room (write), place_furniture (write), set_door (write), move_furniture (write), check_plan (write) and 1 more
