**6 tools: 1 can delete or cancel things, 2 change things and 3 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__stivio__generate_video` `mcp__stivio__get_video_status` `mcp__stivio__upload_image` |
| 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 `get_video_status` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

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


## Deletes or cancels (1)

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

### `generate_video`

- The name "generate_video" says "generate": a word for a change.
- The server marks it destructive (destructiveHint: true).
- 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
Start a paid video job with user approval and an exact expectedCredits quote. Required requestId deduplicates identical retries for 24h. Never use a new id to retry an uncertain submission. Returns taskId. For i2v upload the image first; for t2v select a -t2v model.
```

## Changes things (2)

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

### `get_video_status`

- The name "get_video_status" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- 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
Check your own task. Poll no faster than every 10 seconds. On success returns videoUrl for the MP4; failures use Stivio's refund flow. Can finalize storage or refunds; requires a key.
```

### `upload_image`

- The name "upload_image" says "upload": a word for a change.
- 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
Upload and moderate a PNG/JPEG/WebP image for video generation. Provide raw base64 (no data URL), maximum 3 MiB decoded. Use the returned url as imageUrl or lastFrameUrl. Requires a key. Clients with file/shell access can instead POST multipart file to https://stivio.ai/api/upload with the same Bearer key; do not ask the language model to transcribe image bytes.
```

## Only reads (3)

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

### `estimate_video_cost`

- The description's first verb is "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validate settings and calculate the exact credit cost. Free; does not generate or reserve credits.
```

### `get_credit_balance`

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

Description, as the server wrote it:

```untrusted-server-text
Read your spendable Stivio credit balance. Requires a key; does not reconcile or render videos.
```

### `list_video_models`

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

Description, as the server wrote it:

```untrusted-server-text
List Stivio video models, supported settings and per-second credit rates. Public; no key needed.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__stivio__list_video_models",
      "mcp__stivio__estimate_video_cost",
      "mcp__stivio__get_credit_balance"
    ],
    "ask": [
      "mcp__stivio__upload_image",
      "mcp__stivio__get_video_status"
    ],
    "deny": [
      "mcp__stivio__generate_video"
    ]
  }
}
```

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

- `mcp__stivio__upload_image`: untrusted-input
- `mcp__stivio__generate_video`: untrusted-input
- `mcp__stivio__get_video_status`: untrusted-input
