**4 tools: 2 do something that can't be undone and 2 change things.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |

| Can't be undone | irreversible | 2 | ask |
| Changes things | write | 2 | ask |
| Only reads | read | 0 | allow |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input.

| 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. | `mcp__recipe-scale__convert_units` |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "convert_units" says "convert": a word for a change.
```

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "merge_shopping_list" says "merge": a word for a change that another call does not undo.
```


## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `convert_units`

- The name "convert_units" says "convert": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Convert one cooking amount between units: within volume or weight exactly, or between volume and weight using a built-in density for flour, sugar, brown sugar, butter, water, milk, rice, oats, cocoa or honey. Use for questions like 'how many grams is 2 cups of flour'. Do NOT use to change serving counts (use scale_recipe).
```

### `merge_shopping_list`

- The name "merge_shopping_list" says "merge": a word for a change that another call does not undo.
- 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
Combine several shopping or ingredient lists into one, summing the same item across lists (volumes and weights converted to a friendly unit) and noting which list each came from. Use when shopping for several recipes or meals at once. Do NOT use to resize one recipe (use scale_recipe) or price it (use cost_per_serving).
```

## Changes things (2)

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

### `cost_per_serving`

- 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
Total the cost of a recipe's ingredients and work out the cost per serving and per 10 servings. Use when budgeting a dish, pricing meal prep or comparing recipes on cost. Do NOT use to resize the recipe (use scale_recipe first, then price the scaled amounts here).
```

### `scale_recipe`

- 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
Scale every ingredient in a recipe from one serving count to another (0.1x to 20x), with kitchen-friendly fraction hints; items without a quantity pass through unchanged. Use when cooking for more or fewer people. Do NOT use to change units (use convert_units) or to combine several recipes' ingredients (use merge_shopping_list).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__recipe-scale__scale_recipe",
      "mcp__recipe-scale__convert_units",
      "mcp__recipe-scale__merge_shopping_list",
      "mcp__recipe-scale__cost_per_serving"
    ],
    "deny": []
  }
}
```

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

- `mcp__recipe-scale__convert_units`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:20:53.726Z, unchanged since 2026-10-22T15:20:53.726Z. 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 | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `4` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **high** 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 (2 irreversible, 2 write). Whether a call also works without credentials was not tested: tools are never called.

https://recipe-scale.magicteams.ai/mcp: tools/list returned 4 tools to an anonymous client, including convert_units (irreversible), merge_shopping_list (irreversible), scale_recipe (write), cost_per_serving (write)
```
