It is categorised as a Destructive tool in the Discord MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Discord MCP Server MCP server in PolicyLayer and add a rule for kick_member: 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.
kick_member 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 kick_member 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 kick_member. 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.
kick_member is provided by the Discord MCP Server MCP server (jackglick/discord-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
