Anlyon alternative

Everything your agent needs in Discord. None of the key.

Anlyon has its own Discord integration. Every write runs under a limit you set and comes back with a receipt read from the provider.

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

    • The name "check_invite" says "invite": a word for sending, and what is sent cannot be taken back.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    What it can reach

    • outboundThe name "check_invite" says "invite": it sends or publishes something to other people.

      The server marks "check_invite" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

      What this check looks for
    Description, as the server wrote it
    Look up a Discord invite link or code (discord.gg/abc, discord.com/invite/abc, or just abc). Says whether disdex last saw it working (live), confirmed it dead, is still checking it (pending), or has never seen it (unknown), and which server it leads to, including dead invites, together with other working invites for that server when known.

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 or untrusted-input.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
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.

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.

Run in a terminal.

Claude Code permissions

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

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__discord-servers__search_servers",
      "mcp__discord-servers__get_server",
      "mcp__discord-servers__get_server_activity",

    ],
    "ask": [
      "mcp__discord-servers__check_invite"
    ],
    "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 discord-servers. Review it before you use it.
