**4 tools: 4 change things.**

## 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

- **warn** Annotations that disagree with the tool in `generate_report` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "generate_report" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "generate_report" says "generate": a word for a change.
```


## Changes things (4)

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

### `estimate_capacity`

- 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
How many complete SETS of one product fit in a single container? A product is 1+ carton types with qtyPerSet each (e.g. a table shipping as 2 cartons: top + legs). All cartons of a set ride in the SAME container. Uses real 3D packing (not just volume math) and reports the binding limit (dimension / weight / volume) per container. Omit `containers` to evaluate the standard 20' DC, 40' DC and 40' HC.
```

### `generate_report`

- The name "generate_report" says "generate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Generate a CAD-style PDF + 3D PNG report for a packing job. IMPORTANT: to keep the report consistent with a plan you already produced, pass the `result` object from your previous pack_containers call — the report then renders that exact plan instead of recomputing. Returns base64-encoded PDF + PNG per container.
```

### `pack_containers`

- 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
Pack a list of cargo SKUs into one or more shipping containers using the Kubova solver. Supports bulk loading (cartons straight into the container) and pallet loading (loadingMode:"pallet" + a pallet — cartons are stacked onto pallets first, then the pallets loaded). Per-SKU you can set allowed orientations, no-overstack/no-understack, and loading order. Returns per-container placements with x,y,z coordinates in cm, volume utilization, weight, a weightBalance object (centre of gravity + front/back & left/right weight split, flags an unbalanced load) for bulk loads, and any unplaced pieces.
```

### `verify_key`

- 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
Verify the connection. Returns the authenticated account identity and plan.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `container-loading`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__container-loading__pack_containers",
      "mcp__container-loading__generate_report",
      "mcp__container-loading__estimate_capacity",
      "mcp__container-loading__verify_key"
    ],
    "deny": []
  }
}
```

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://kubova.com/mcp: tools/list returned 4 tools to an anonymous client, including pack_containers (write), generate_report (write), estimate_capacity (write), verify_key (write)
