**6 tools: 1 change things and 5 only read.**

## 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__fmcg-network__lookup_nutrients` `mcp__fmcg-network__run_check` |
| 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 `run_check` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

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


## Changes things (1)

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

### `run_check`

- The name "run_check" says "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Run one check and get a cited answer. Pass check_id and the check's own arguments (see describe_check).
```

## Only reads (5)

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

### `describe_check`

- The name "describe_check" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Inputs, output, market and coverage of one check, plus a ready run_check call.
```

### `get_source`

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

Description, as the server wrote it:

```untrusted-server-text
The registers, regulations and references a check answers from, with licence and citation text.
```

### `list_regulations`

- The name "list_regulations" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Regulations and live registers the checks cover, each with its check_ids. Optional market filter.
```

### `lookup_nutrients`

- The name "lookup_nutrients" says "lookup": 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
Nutrient composition of a food from USDA FoodData Central: finds the best match for a query (or takes an fdc_id) and returns its nutrients with the record's data type and date.
```

### `search_checks`

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

Description, as the server wrote it:

```untrusted-server-text
Find food, cosmetics and FMCG compliance checks by keyword and market (us, eu, uk). Returns check_ids for describe_check and run_check. An empty query lists all checks.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__fmcg-network__search_checks",
      "mcp__fmcg-network__describe_check",
      "mcp__fmcg-network__get_source",
      "mcp__fmcg-network__list_regulations",
      "mcp__fmcg-network__lookup_nutrients"
    ],
    "ask": [
      "mcp__fmcg-network__run_check"
    ],
    "deny": []
  }
}
```

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

- `mcp__fmcg-network__run_check`: untrusted-input
- `mcp__fmcg-network__lookup_nutrients`: untrusted-input

## Remote posture

- **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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.fmcg.network/mcp: tools/list returned 6 tools to an anonymous client, including run_check (write)
