Delete a collection (folder).
AI agents call delete_collection to permanently remove resources in Metabase Mcp Navi — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a collection irreversibly removes an entire folder and its contents. This cannot be undone and represents permanent data loss. Although it does not directly move money, it is more severe than Execute or Write because the action is destructive and affects organizational data structures. The blast radius is high if an AI agent mistakenly deletes a collection containing important dashboards or queries.
From the tool's definition Tool name is 'delete_collection' and description states 'Delete a collection (folder).' The verb 'delete' combined with an operation on a collection (a container of data/dashboards/cards) indicates irreversible data removal.
Attacks that exploit this kind of access
Delete a collection (folder). It is categorised as a Destructive tool in the Metabase Mcp Navi MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Metabase Mcp Navi MCP server in PolicyLayer and add a rule for delete_collection: 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 Metabase Mcp Navi. Nothing to install.
delete_collection 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_collection 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_collection. 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_collection is provided by the Metabase Mcp Navi MCP server (manish-coder-1007/metabase-mcp-navi). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
