create_invite · Discord MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_invite does on Discord MCP Server

AI agents use create_invite 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.

WHY IT NEEDS A POLICY

Why create_invite needs a policy

This tool creates new invite links, which is a write operation that adds a resource to the system. It has minimal blast radius — invite links do not directly modify existing data, delete anything, execute code, or move money. The worst-case misuse (generating many invites) would be inconvenient but easily remedied by revoking them. This is clearly Write, not Destructive or Execute.

From the tool's definition Tool name is 'create_invite' and description states 'Create a custom invite link' — this creates a new resource (an invite link) that can be shared to allow others to join the Discord server.

create_invite Rate-limited

create_invite 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.
