Delete a basin. This is irreversible.
AI agents call delete_basin to permanently remove resources in S2 StreamStore MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a basin is an irreversible operation that destroys data structures and associated resources. This meets the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone.' While not as critical as financial operations, the permanent loss of a basin and its contents (confirmed by 'irreversible' language) justifies 'high' severity, as an AI agent misusing this…
From the tool's definition Tool name is 'delete_basin' and description explicitly states 'Delete a basin. This is irreversible.' The irreversibility clause directly indicates data cannot be recovered.
Attacks that exploit this kind of access
Delete a basin. This is irreversible. It is categorised as a Destructive tool in the S2 StreamStore MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the S2 StreamStore MCP Server MCP server in PolicyLayer and add a rule for delete_basin: 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 S2 StreamStore MCP Server. Nothing to install.
delete_basin 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 delete_basin 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 delete_basin. 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.
delete_basin is provided by the S2 StreamStore MCP Server MCP server (s2-streamstore/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
