Unban a member from a Discord guild. Defaults to dry-run mode.
AI agents use discord.member.unban to create or update resources in Discord MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Discord MCP Server environment.
Unbanning a member reverses a previous ban, restoring access to a Discord guild. This is a reversible write operation (the member can be re-banned), not destructive. The dry-run default reduces misuse risk, but if triggered, it grants a previously-banned user access back to the server, which could have moderate security implications.
From the tool's definition 'Unban a member from a Discord guild. Defaults to dry-run mode.'
Documented attack patterns abuse exactly the kind of access discord.member.unban gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Discord MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for discord.member.unban:
{
"version": "1",
"default": "deny",
"tools": {
"discord.member.unban": {
"limits": [
{
"counter": "discord.member.unban_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}discord.member.unban stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
