WHAT IT DOES

What discord_add_member_role does on Discord

AI agents use discord_add_member_role to create or update resources in Discord, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Discord environment.

RISK

Why discord_add_member_role is rated Medium

Adding a role to a member modifies access control and permissions within the Discord server, which is a state change. However, it is reversible (the role can be removed), so it does not qualify as Destructive. It does not execute arbitrary code or external operations, so Execute does not apply. This is straightforward data modification (Write).

From the tool's definition Tool name 'discord_add_member_role' and description 'Add a role to a guild member' indicate creation/modification of member attributes in Discord. This is a write operation that modifies guild state reversibly.
