| Group | Class | Tools | Claude Code |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| 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__youtube-transcripts__get_download_url` `mcp__youtube-transcripts__get_job_status` `mcp__youtube-transcripts__get_transcript` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__youtube-transcripts__start_channel_job` |

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__youtube-transcripts__get_transcript",
      "mcp__youtube-transcripts__get_channel_info",
      "mcp__youtube-transcripts__list_channel_videos",
      "mcp__youtube-transcripts__get_job_status",
      "mcp__youtube-transcripts__get_download_url"
    ],
    "ask": [
      "mcp__youtube-transcripts__start_channel_job",
      "mcp__youtube-transcripts__start_playlist_job"
    ],
    "deny": [
      "mcp__youtube-transcripts__cancel_job"
    ]
  }
}
```

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

- `mcp__youtube-transcripts__get_transcript`: untrusted-input
- `mcp__youtube-transcripts__start_channel_job`: outbound
- `mcp__youtube-transcripts__get_job_status`: untrusted-input
- `mcp__youtube-transcripts__get_download_url`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:59:05.423Z, unchanged since 2026-10-22T14:59:05.423Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `3` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **high** 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 3 tools that change things (1 destructive, 2 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.youtubetranscripts.fbetteo.com/mcp: tools/list returned 8 tools to an anonymous client, including cancel_job (destructive), start_channel_job (write), start_playlist_job (write)
