AI agents call delete_tenant to permanently remove resources in Mcp Oceanbase — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool name 'delete_tenant' clearly indicates deletion of a tenant entity. Tenant deletion is an irreversible operation that cannot be undone and would result in permanent loss of data and infrastructure. This represents the most severe category (Destructive) due to its irreversible nature and high blast radius if invoked erroneously by an AI agent.
From the tool's definition Tool name is 'delete_tenant' which indicates irreversible deletion of a tenant resource. Description is empty but the naming is explicit.
Documented attack patterns abuse exactly the kind of access delete_tenant gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Oceanbase, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_tenant:
{
"version": "1",
"default": "deny",
"hide": [
"delete_tenant"
]
}delete_tenant disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

delete_tenant. It is categorised as a Destructive tool in the Mcp Oceanbase MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp Oceanbase MCP server in PolicyLayer and add a rule for delete_tenant: 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 Mcp Oceanbase. Nothing to install.
delete_tenant 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_tenant 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_tenant. 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_tenant is provided by the Mcp Oceanbase MCP server (oceanbase/awesome-oceanbase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
