Delete a storage bucket from Supabase. The bucket must be empty before deletion. Use sb_delete_objects to remove files first.
Part of the Supabase MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents may call sb_delete_bucket to permanently remove or destroy resources in Supabase. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call sb_delete_bucket in a loop, permanently destroying resources in Supabase. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.

sb_delete_bucket 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 sb_delete_bucket rule in your Intercept 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 Intercept policy for sb_delete_bucket. 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.
sb_delete_bucket is provided by the Supabase MCP server (@supabase-community/supabase-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
