Modify a Discord guild. Defaults to dry-run mode.
AI agents use discord.guild.modify 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.
This tool modifies a Discord guild (server), which includes potentially sensitive server-wide settings such as name, icon, region, verification level, and ownership. Changes are reversible in principle but can have broad blast radius affecting all members. The dry-run default slightly lowers immediate risk but the live mode is Write with high severity due to guild-wide impact.
From the tool's definition 'Modify a Discord guild' — modifies server-level settings; 'Defaults to dry-run mode' suggests actual execution is possible
Documented attack patterns abuse exactly the kind of access discord.guild.modify 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.guild.modify:
{
"version": "1",
"default": "deny",
"tools": {
"discord.guild.modify": {
"limits": [
{
"counter": "discord.guild.modify_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}discord.guild.modify 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.

Modify a Discord guild. Defaults to dry-run mode. It is categorised as a Write tool in the Discord MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Discord MCP Server MCP server in PolicyLayer and add a rule for discord.guild.modify: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Discord MCP Server. Nothing to install.
discord.guild.modify is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the discord.guild.modify rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for discord.guild.modify. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
discord.guild.modify is provided by the Discord MCP Server MCP server (rastrian/discordmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Discord MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
