Remove ALL permission overwrites on a channel, so only role/server-level permissions apply. Does NOT re-sync with the category — use discord_lock_channel_permissions for that. IRREVERSIBLE — the cleared overwrites cannot be recovered. Requires the Manage Roles permission.
AI agents call discord_reset_channel_permissions to permanently remove resources in Discord — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes permission configurations. Once overwrites are cleared, they cannot be recovered, making it a destructive operation. While the blast radius is primarily limited to a single channel's permissions (not organization-wide), the irreversible nature and the potential for significant disruption to channel access control justifies 'high' severity.
From the tool's definition 'Remove ALL permission overwrites on a channel' and 'IRREVERSIBLE — the cleared overwrites cannot be recovered.' The tool explicitly deletes all permission data on a channel with no undo mechanism.

IRREVERSIBLE — the cleared overwrites cannot be recovered. Requires the Manage Roles permission. It is categorised as a Destructive tool in the Discord MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Discord MCP server in PolicyLayer and add a rule for discord_reset_channel_permissions: 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. Nothing to install.
discord_reset_channel_permissions is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the discord_reset_channel_permissions 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_reset_channel_permissions. 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_reset_channel_permissions is provided by the Discord MCP server (@pasympa/discord-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
