**4 tools: 2 change things and 2 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 2 | ask |
| Only reads | read | 2 | allow |

## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__calories__list_chains` |
| 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 `sum_items` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "add": a word for a change.
```


## Changes things (2)

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

### `request_missing`

- The name "request_missing" says "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Tell the site operator that a restaurant chain or menu item is missing. Use only after search_menu / list_chains could not find it AND the user actually wanted it. One request per chain or item. Only the chain, item and note are stored (no personal information is needed or kept). Requests are counted (not shown publicly) and used to decide what to add next. Some chains do not publish nutrition values at all, so a request does not guarantee coverage.
```

### `sum_items`

- The description's first verb is "add": 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
Add up nutrition for a set of items (a meal, a day) using ids from search_menu. Nutrients that some items do not publish are reported in incomplete, because their total is an underestimate.
```

## Only reads (2)

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

### `list_chains`

- The name "list_chains" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
List the restaurant chains covered, with item counts, which nutrients each chain publishes, the source document and when it was fetched. query filters by chain name.
```

### `search_menu`

- The name "search_menu" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search menu items of Japanese restaurant chains and get their nutrition facts. Queries that return no results are counted anonymously (the query text and chain only) to decide which chains to add. query matches item name, size, category, genre and chain name (Japanese; spaces mean AND; katakana/hiragana and full/half width are treated alike; common chain nicknames like ケンタ, マック, サイゼ work). Combine with chain / genre / kcal range. Use nutrient to find items rich in a nutrient (only chains that publish it). With a query, results are sorted by how well the item name matches (default sort "relevance"); otherwise by kcal ascending. Each item has an id for sum_items, a page url, and the chain's source_file.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__calories__search_menu",
      "mcp__calories__list_chains"
    ],
    "ask": [
      "mcp__calories__sum_items",
      "mcp__calories__request_missing"
    ],
    "deny": []
  }
}
```

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

- `mcp__calories__list_chains`: private-data

- **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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://calories.omikuji.dev/mcp: tools/list returned 4 tools to an anonymous client, including sum_items (write), request_missing (write)
