activate_tenant

THE RISK

High Risk

The tool name suggests activating a tenant in an OceanBase database cluster, which is an operational state-change action (enabling a previously inactive or standby tenant). This is likely an Execute-level operation as it triggers an external system state change. However, the empty description significantly lowers confidence. It could also be Write if it merely updates tenant status.

From the tool's definition Tool name 'activate_tenant' on an OceanBase server; description is empty or uninformative.

HOW TO CONTROL ACTIVATE_TENANT

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 activate_tenant:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "activate_tenant": {
      "limits": [
        {
          "counter": "activate_tenant_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

activate_tenant stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Mcp Oceanbase — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
