1 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.

create_short_linkShorten a public website for easy typing on a TV remote, console browser, phone or computer.Reads text others writeCan send data outNo findings
Why it is in this group
- The name "create_short_link" says "create": a word for a change.
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 Shorten a public website for easy typing on a TV remote, console browser, phone or computer. Returns a short preview URL, four digits, one-hour idle expiry and instructions. Free beta, no account or API key. Appropriate for temporary device handoff; not permanent bookmarks, private links, casting or sign-in transfer. Publishes the submitted URL behind a guessable code. Requires a fresh random UUID request_id; reuse the same URL and ID for retries. Five new attempts per network daily and shared beta capacity; do not evade limits.
Annotations the server declares

Why it is in this group
- The name "get_service_info" says "get": a word for reading.
Description, as the server wrote it Read what LKJ does, whether new agent links are currently enabled, its fair-use limits and when to choose four-digit temporary links. Does not create or open a code, check a destination or consume a creation allowance.

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.
Install
Pinned to version 0.6.0. Values in angle brackets are yours to fill in.

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [
"mcp__short-links__get_service_info"
],
"ask": [
"mcp__short-links__create_short_link"
],
"deny": []
}
}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 short-links. Review it before you use it.
