## 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__vngrd__vngrd_bassline` `mcp__vngrd__vngrd_beat` `mcp__vngrd__vngrd_cover_art` `mcp__vngrd__vngrd_subtitles` `mcp__vngrd__vngrd_transcribe` `mcp__vngrd__vngrd_voice` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__vngrd__vngrd_subtitles` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `vngrd_subtitles`

- The description's first verb is "broadcast": a word for sending, and what is sent cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The description's first verb is "broadcast": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Broadcast-style subtitles for a video or podcast: transcribed, timed and translated into up to 3 languages, as SRT and WebVTT files ready to upload to YouTube, Instagram, TikTok or a player. Up to 15 minutes and 20 MB. Price: $0.15 USDC on Base, paid per call with x402 (send the payment in _meta["x402/payment"]; a call without it returns the payment requirements).
```

## Changes things (7)

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