## 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 (3)

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

### `check_cells_available`

- 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
Price a selection of cells right now and say whether it can be ordered (meets the minimum, not reserved, not in image review). Nothing is reserved or charged. Wraps POST /api/quote. Wall coordinates: x 0..999 (left to right), y 0..999 (top to bottom); cell index = y*1000 + x.
```

### `create_order`

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

Description, as the server wrote it:

```untrusted-server-text
Create an order for cells and return the USDC payment details (recipient wallet, token, amount_units, Solana reference, pay_by, status URL). This tool does not pay: the caller sends the USDC transfer itself before pay_by. Same validation and limits as the website (minimum cells, at most 16 colours (image orders are not supported here), rate limits, unpaid orders per IP). accepted_terms must be true and means you accept the terms at https://cellionaire.com/terms. Wall coordinates: x 0..999 (left to right), y 0..999 (top to bottom); cell index = y*1000 + x.
```

### `wall_overview`

- 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
Current wall version, the URL of the full-wall PNG (1 pixel = 1 cell; alpha 0 empty, 255 bought, 254 site-owned house art) and how to read regions. Wraps GET /api/wall. No input.
```

## Only reads (3)

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

### `get_order_status`

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

Description, as the server wrote it:

```untrusted-server-text
Status of an order and its USDC payment (state, received, remaining, confirmations, refunds). Wraps GET /api/order/{id}. status: pending, processing, paid, pending_review, expired, cancelled, late_paid, refund_pending, refunded, failed.
```

### `get_wall_info`

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

Description, as the server wrote it:

```untrusted-server-text
Rules, prices, size, minimum order, payment networks, terms version and whether purchases are open. Numbers come from the live settings. No input.
```

### `read_region`

- The name "read_region" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Pixels and owners of a rectangle (w*h <= 10000). format "json" (default): base64 RGBA pixels plus runs of empty / buyer (with public display name) / house cells. format "png": the rectangle as a PNG image. Wraps GET /api/region. Wall coordinates: x 0..999 (left to right), y 0..999 (top to bottom); cell index = y*1000 + x.
```
