Destroy consumer group.
AI agents call stream_group_destroy to permanently remove resources in AWS IoT SiteWise MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool performs an irreversible destructive action on a consumer group stream resource. While not a database drop or file deletion, destroying a consumer group eliminates message queue state, offset tracking, and group metadata that typically cannot be recovered. This is categorized as Destructive rather than Execute because the action is inherently destructive in nature and unrecoverable.
From the tool's definition Tool name 'stream_group_destroy' combined with description 'Destroy consumer group' indicates irreversible deletion of a resource. The verb 'Destroy' explicitly signals permanent removal with no undo capability.
Attacks that exploit this kind of access
Destroy consumer group. It is categorised as a Destructive tool in the AWS IoT SiteWise MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the AWS IoT SiteWise MCP Server MCP server in PolicyLayer and add a rule for stream_group_destroy: 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 AWS IoT SiteWise MCP Server. Nothing to install.
stream_group_destroy 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 stream_group_destroy 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 stream_group_destroy. 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.
stream_group_destroy is provided by the AWS IoT SiteWise MCP Server MCP server (awslabs.aws-iot-sitewise-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
