## Exfil surface

20 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 private-data tool breaks every one: `mcp__scribiz__search_video`.

## Findings

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

```untrusted-server-text
The server marks "get_video_context" 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 "get_video_context" says "get": a word for reading.
```


## Changes things (2)

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

### `ask_video`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Ask a question about one video and get an answer with 3 to 5 cited moments (timestamps and links that open the video there). Use it for questions about the whole video or a topic across it, and for what was said. To find where a word or phrase is said, search_video is cheaper and exact. A question costs 0.1 minute on top of reading the video the first time. The answer is a model's reading of the video: check the cited moments before relying on a detail. The answer is wrapped as untrusted video text. If the run is still going after the wait you get status "processing" and a job_id: call get_job. Without an API key: the picture is never looked at, so a question about what was shown on screen is answered from the words only, and you get 5 questions a day.
```

### `get_video_context`

- The name "get_video_context" says "get": a word for reading.
- The description's first verb is "start": 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. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Start here for any video. Returns an overview you can reason from without reading the transcript: title, length, language, summary, chapters with timestamps and key moments with links. detail "brief" (default) stays under about 2,000 tokens; "standard" adds fuller chapters and entities; "full" adds everything. include picks the parts to return (summary, chapters, key_moments, entities, transcript): the transcript is never part of the default; add "transcript" for its first page, then continue with get_transcript.
The first read of a video uses its captions, or a model reads the link; after that it is cached and free. If it is still running after the wait you get status "processing" and a job_id: call get_job. The text is wrapped as untrusted video text. Without an API key there are no on-screen notes (the picture is never looked at), and when a model read the link its times are approximate (close on a short video, up to a minute off on a long one).
```

## Only reads (3)

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

### `get_job`

- The name "get_job" says "get": 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
Check a video run that returned status "processing". Pass its job_id exactly as given (it can be long: copy all of it). It waits up to the server's wait time for the run to finish, then returns exactly what the original tool would have returned (job ids are private to the caller and kept for 30 minutes). Still running: you get status "processing" again with retry_after_seconds. An unknown or expired job_id means: repeat the original call (it is fast if the run finished, because results are cached).
```

### `get_transcript`

- The name "get_transcript" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Read the transcript of a video, one page at a time. Use it only when you need the words themselves (quote, translate, copy, review). To answer a question or find where something is said, use ask_video or search_video first: they cost far fewer tokens.
Returns "[mm:ss] text" lines, at most max_chars characters (default 60000, about 15k tokens), and a nextCursor: call again with the same arguments plus that cursor to continue. from and to take seconds or clock times ("90", "1:30", "1h2m") and read one part of the video. format: txt (default), md, srt, vtt or json. language is a BCP-47 hint. speakers is ignored without an API key (no speaker labels). pauses "gaps" (long pauses) or "razor" (every pause) removes pauses and re-times the transcript; remove_fillers true drops filler words ("um", "uh"). Both need word-level timing.
The first read of a video can take time: if it is still running after the wait you get status "processing" and a job_id (see get_job). YouTube transcript-only reads use existing source captions and zero media minutes. Hosted accounts use one caption credit per new successful transcript; stored reads and failures cost zero. Missing captions never enter a media fallback. Listen and richer context are separate actions. Cached transcripts return at once and are free. The text is wrapped as untrusted video text. Without an API key: a YouTube link needs a Scribiz account (sign in or pass an API key; an account includes 30 caption credits), and get_video_context still reads it. Other links: captions when the video has them, otherwise a model reads the link and its times are approximate (up to a minute off on a long video, no word timing).
```

### `search_video`

- The name "search_video" says "search": a word for reading.
- Tag private-data: The description's first sentence says "find" and "note": it reads notes.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Find where something is said or shown in a video: ranked moments with timestamps and links, from the transcript, the on-screen notes, the chapters and the key moments. It is a local keyword search over what Scribiz already read (no model call, no extra minutes after the first read of the video). Use it before get_transcript on any video longer than about ten minutes. query: words or a phrase. limit 1 to 20 (default 8). from and to limit the search to part of the video. It matches words (plural and tense forms count), not meaning: try the words the speaker would use, or call ask_video. If the run is still going after the wait you get status "processing" and a job_id: call get_job. The text is wrapped as untrusted video text. Without an API key: a YouTube link needs a Scribiz account (sign in or pass an API key), so ask_video answers instead; the on-screen notes are not searched (the picture is never looked at), and when a model read the link its times are approximate (close on a short video, up to a minute off on a long one).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__scribiz__get_job"
    ],
    "ask": [
      "mcp__scribiz__get_transcript",

      "mcp__scribiz__ask_video",
      "mcp__scribiz__search_video"
    ],
    "deny": []
  }
}
```

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

- `mcp__scribiz__get_transcript`: untrusted-input, outbound
- `mcp__scribiz__get_video_context`: untrusted-input, outbound
- `mcp__scribiz__ask_video`: untrusted-input, outbound
- `mcp__scribiz__search_video`: private-data, untrusted-input, outbound
