edit_role · Discord MCP Server MCP: Risk & Policy

WHAT IT DOES

What edit_role does on Discord MCP Server

AI agents use edit_role 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 edit_role needs a policy

The tool performs reversible modifications to Discord roles. While editing roles can have significant blast radius (e.g., reducing admin permissions, changing visibility), the action is not irreversible—roles can be edited again to restore previous state. This places it in the Write category rather than Destructive.

From the tool's definition Tool name is 'edit_role' and description states 'Edit an existing role'. This modifies existing role configurations (permissions, name, color, etc.) in a Discord server but does not permanently delete roles or create destructive irreversible changes.

Verdict

edit_role Rate-limited

edit_role 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.
