Delete rows from Knowledge Matrix with confirmation requirement. First call shows preview, second call with confirm=true executes deletion. Cannot delete header rows (1-2).
AI agents call delete_matrix_rows to permanently remove resources in Revenue Engine MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes data rows from a structured knowledge management system. Although it includes a safety mechanism (two-step confirmation with preview), the core action is irreversible deletion of data. This qualifies as Destructive rather than Write because the operation cannot be undone.
From the tool's definition Tool name 'delete_matrix_rows' and description explicitly states it 'Delete rows from Knowledge Matrix'. Deletion is irreversible data destruction.
Attacks that exploit this kind of access
Delete rows from Knowledge Matrix with confirmation requirement. First call shows preview, second call with confirm=true executes deletion. Cannot delete header rows (1-2). It is categorised as a Destructive tool in the Revenue Engine MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Revenue Engine MCP server in PolicyLayer and add a rule for delete_matrix_rows: 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 Revenue Engine MCP. Nothing to install.
delete_matrix_rows 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_matrix_rows 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_matrix_rows. 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_matrix_rows is provided by the Revenue Engine MCP server (promptishoperations/mcpspec). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
