Permanently delete a table and all its data.
AI agents call delete_table to permanently remove resources in Dune — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool performs an irreversible deletion operation (delete_table) that destroys data completely. It cannot be undone and eliminates an entire dataset and its schema. While not financial in nature, it is more severe than Write or Execute because the effects are permanent and unrecoverable.
From the tool's definition 'Permanently delete a table and all its data' — the tool irreversibly removes data without recovery options.
Attacks that exploit this kind of access
Permanently delete a table and all its data. It is categorised as a Destructive tool in the Dune MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Dune MCP server in PolicyLayer and add a rule for delete_table: 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 Dune. Nothing to install.
delete_table 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_table 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_table. 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_table is provided by the Dune MCP server (mwamedacen/dune-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
delete_table is one line of Dune's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
