Archive/Delete a query. (Requires Paid Plan)
AI agents call archive_query 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.
Archiving or deleting a query permanently removes it from Dune Analytics. This is a destructive action that cannot be undone, making it the most severe applicable category. The blast radius is high because saved queries may be shared, relied upon by dashboards or automated workflows, and losing them could disrupt analytics pipelines.
From the tool's definition Archive/Delete a query — the tool explicitly states it archives or deletes a query, which is an irreversible removal of data.
Attacks that exploit this kind of access
Archive/Delete a query. (Requires Paid Plan). 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 archive_query: 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.
archive_query 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 archive_query 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 archive_query. 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.
archive_query is provided by the Dune MCP server (nice-bills/dune-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
