## 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__rotation__list_active_groups` |
| 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 (1)

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

### `check_rotation`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Check a beekeeper's varroa treatment history against published resistance-rotation guidance. Deterministic rules only — no AI. Returns violations (same active group repeated, label withdrawal period breached), cautions, and the inputs it could not judge.
```

## Only reads (2)

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

### `get_thresholds`

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

Description, as the server wrote it:

```untrusted-server-text
Published varroa damage thresholds with their exact source, plus the monitoring cadence the guidance asks for. Quoted study values — not a recommendation.
```

### `list_active_groups`

- The name "list_active_groups" says "list": a word for reading.
- Tag private-data: The description's first sentence says "table": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
The active-group table this service rotates on: product, active ingredient, and IRAC mode-of-action group. Cite the group number when you record a treatment.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__rotation__list_active_groups",
      "mcp__rotation__get_thresholds"
    ],
    "ask": [
      "mcp__rotation__check_rotation"
    ],
    "deny": []
  }
}
```

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

- `mcp__rotation__list_active_groups`: private-data

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:19:35.313Z, unchanged since 2026-10-22T15:19:35.313Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#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://hive-ledger.rowb.app/mcp: tools/list returned 3 tools to an anonymous client, including check_rotation (write)
