  • Each tool you adopt gets approvals and receipts.
  • Your agent never holds the key.

A tool your agent calls directly is not routed through Anlyon and is not governed by it. anlyon.dev only lists and labels, and these labels are the same either way.

What the YouTube Transcript, Comments & Video Data API MCP Server can do

The YouTube Transcript, Comments & Video Data API MCP Server is published by youtubeapi.io, a domain the MCP Registry verified. It has 8 tools. It can create or change data (2 tools: youtube_transcript and youtube_comments), but cannot delete data. 6 tools only read.

1 tool brings in text other people can write (youtube_channel); 1 tool can send data out of your system (youtube_channel).

None of the fixed checks matched anything in its tool definitions. That is not a safety guarantee.

Last scanned Nov 5, 2026, version 1.0.1.

  • youtube_transcriptExtract timed subtitle segments (offset_ms, duration_ms) and complete plain-text transcript for any YouTube video or Short.No findings

    Why it is in this group

    Why it is in this group

    • The description's first verb is "resolve": a word for reading.

    What it can reach

    • untrusted-inputThe description's first sentence says "resolve" and "url": it reads web pages, which anyone can write.
    • untrusted-inputThe input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
    • outboundThe 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

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

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

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write1
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out1
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as youtubeapi. Review it before you use it.
