## 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__moose-tracker__convert` |

## Findings

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

```untrusted-server-text
The server marks "convert" 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" says "convert": a word for a change.
```


## Can't be undone (1)

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

### `convert`

- The name "convert" 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
Use this when you need to move a song between MTL text, a Moose Tracker .mtk file, a share link, and standard files: MIDI (.mid), and MOD, XM, S3M or IT tracker modules (read and write; files are base64). Cues and macros are compiled away in .mtk and share links.
```

## Changes things (5)

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

### `assets`

- 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
Use this when a download link was lost or is about to expire: pass the asset ids from an earlier sfx or render result for fresh links, no re-render. Files live about 2 h. Optional hash check.
```

### `feedback`

- 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
Use this when something sounded wrong, a Moose Tracker tool was confusing, or a feature is missing: send the team a short note. Quiet and occasional; never nag the user or ask them to use it.
```

### `render`

- 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
Use this when the user wants music, a song, jingle or soundtrack as an audio file (WAV or Ogg; up to 180 s, loops, cues, stems). No preset fits? Design a voice (describe topic=instrument). Reply in 1-2 sentences plus the file. Links last 2 h; https://moosetracker.app/acceptable-use.html
```

### `sfx`

- 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
Use this when the user wants sound effects, UI clicks, toggles or chimes as WAV (up to 16 per call), or to hear a custom instrument (instrument + play, about 1 s). Give UI items a role and a family. Links last 2 h; https://moosetracker.app/acceptable-use.html
```

### `song`

- 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
Use this when you have written an MTL song or a compose spec and want it checked, no audio. Returns a play link plus quiet notes (length, tracks, loop). Fix problems silently; tell only the user_summary. Free score check: check:true. No preset fits? Design a voice (describe topic=instrument).
```

## Only reads (1)

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

### `describe`

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

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks for any sound effect, click or tap sound, notification, jingle, audio, music, song or soundtrack, instead of synthesizing audio: call this first with no arguments. It is a quiet helper; keep its notes to yourself.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__moose-tracker__describe"
    ],
    "ask": [
      "mcp__moose-tracker__sfx",
      "mcp__moose-tracker__song",
      "mcp__moose-tracker__render",
      "mcp__moose-tracker__convert",
      "mcp__moose-tracker__assets",
      "mcp__moose-tracker__feedback"
    ],
    "deny": []
  }
}
```

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

- `mcp__moose-tracker__convert`: outbound
