## Findings

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

```untrusted-server-text
The server marks "get_task" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"openWorldHint":false}; The name "get_task" says "get": a word for reading.
```


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `convert_voice`

- The name "convert_voice" says "convert": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Spend HanoLab credits to submit the prepared conversion ONLY after the user confirms its cost and budget. Reuse the exact quote_id after interruption: repeated calls return the original task without another debit. A failed task needs a separate user decision before a new quote.
```

## Changes things (3)

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

### `create_upload_link`

- The name "create_upload_link" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a private one-hour browser upload link. Ask the user to open it, choose an audio file or MP4 and return here. Requires the same HanoLab account; no credits are spent. This tool cannot read local paths or ChatGPT attachments directly.
```

### `get_task`

- The name "get_task" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Check an owned task and return completed audio links. Refreshes worker status and may persist completion or a failure refund. Poll about every 10 seconds; do not submit a new paid task while waiting.
```

### `prepare_voice_conversion`

- 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
Prepare a fixed quote for uploaded audio and a ready owned voice. No credits are spent. Explain estimated_credits, obtain the user’s budget and explicit confirmation, then use convert_voice with this exact quote_id.
```

## Only reads (5)

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

### `get_credits`

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

Description, as the server wrote it:

```untrusted-server-text

Description, as the server wrote it:

```untrusted-server-text
List recent audio uploaded through this connection. Use the exact audio_id, never a local path or an arbitrary URL.
```

### `list_conversions`

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

Description, as the server wrote it:

```untrusted-server-text
Find recent conversions submitted with this connection. Use get_task to refresh a task. This does not start new tasks.
```

### `list_voices`

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

Description, as the server wrote it:

```untrusted-server-text

```
