Delete a file from DUAL storage.
AI agents call dual_delete_file to permanently remove resources in DUAL MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of files is a destructive action that cannot be undone. Even though the blast radius depends on file sensitivity and backup policies, the irreversible nature of the operation and the context of a blockchain/Web3 system where files may contain critical data (keys, contracts, configurations) warrants high severity. Confidence is very high given the explicit 'delete' language in both name and description.
From the tool's definition Tool name is 'dual_delete_file' and description explicitly states 'Delete a file from DUAL storage.' The verb 'delete' is unambiguous and irreversible.
Attacks that exploit this kind of access
Delete a file from DUAL storage. It is categorised as a Destructive tool in the DUAL MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the DUAL MCP Server MCP server in PolicyLayer and add a rule for dual_delete_file: 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 DUAL MCP Server. Nothing to install.
dual_delete_file 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 dual_delete_file 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 dual_delete_file. 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.
dual_delete_file is provided by the DUAL MCP Server MCP server (ro-ro-b/dual-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
