Anlyon alternative

30 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Why it is in this group
- 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.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
Description, as the server wrote it
YouTube video transcript as text. Subtitles of a YouTube video (manual or auto-generated) as plain text, optionally with timestamps, plus title and channel. Picks the requested language or the best available. Cached 6 h. Price $0.010 per call (x402: USDC on Base or Solana).
Annotations the server declares
- readOnlyHint: true

What it can reach

- 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.

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 write33: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; arbitrage

Can send data out6: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; evm_call

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

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 crypto-web-data-api. Review it before you use it.
