Permanently deletes a group chat from RongCloud.
AI agents call dismiss_group to permanently remove resources in RongCloud MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes data (a group chat) from RongCloud, which cannot be undone. This is a classic destructive operation that aligns with the Destructive category definition. The severity is high because deleting a group chat affects all members and loses all associated message history and group state, making it a significant operation with broad impact if triggered by mistake or malicious agent behavior.
From the tool's definition Tool description states "Permanently deletes a group chat" - the word "deletes" is explicit and "permanently" confirms irreversibility.
Attacks that exploit this kind of access
Permanently deletes a group chat from RongCloud. It is categorised as a Destructive tool in the RongCloud MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the RongCloud MCP Server MCP server in PolicyLayer and add a rule for dismiss_group: 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 RongCloud MCP Server. Nothing to install.
dismiss_group 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 dismiss_group 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 dismiss_group. 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.
dismiss_group is provided by the RongCloud MCP Server MCP server (rongcloud/rongcloud-server-mcp-python). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
