Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as data. Review it before you use it.

Keep track

Get told when this server's tools change: a new tool, a new description, a new class.

https://anlyon.dev/servers/se.aleva/data/changes.xml

An Atom feed. Works in any feed reader or Slack's RSS app.

Anlyon alternative

44 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.
