Remove an object from a MinIO bucket
AI agents call minio_remove_object to permanently remove resources in MinIO MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of stored objects is an irreversible action that destroys data. This falls under the Destructive category, which takes precedence over Write operations. Severity is high because unintended deletion of objects in production storage could result in significant data loss, though the blast radius depends on what data is stored and access controls in place.
From the tool's definition Tool name 'minio_remove_object' and description 'Remove an object from a MinIO bucket' indicate deletion of data. The operation is irreversible—once removed, the object cannot be recovered without external backups.
Attacks that exploit this kind of access
Remove an object from a MinIO bucket. It is categorised as a Destructive tool in the MinIO MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MinIO MCP Server MCP server in PolicyLayer and add a rule for minio_remove_object: 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 MinIO MCP Server. Nothing to install.
minio_remove_object 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 minio_remove_object 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 minio_remove_object. 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.
minio_remove_object is provided by the MinIO MCP Server MCP server (raphaelren/minio-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
