Get OceanBase cluster Zone list This interface is used to query the Zone list of an OceanBase cluster. Args: cluster_id: The ID of the OceanBase cluster to query Zone list Returns: Dictionary containing Zone list and pagination information
AI agents call get_oceanbase_cluster_zones to retrieve information from Mcp Oceanbase without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves cluster zone information from OceanBase without any side effects. It is a read-only query operation that fetches existing data about cluster zones. The narrow scope (zone list metadata only), lack of external execution, and informational nature classify it as a low-severity Read operation.
From the tool's definition Tool description explicitly states 'query the Zone list' and 'Returns: Dictionary containing Zone list' - pure data retrieval with no modification, deletion, or execution capabilities.
Documented attack patterns abuse exactly the kind of access get_oceanbase_cluster_zones 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 get_oceanbase_cluster_zones:
{
"version": "1",
"default": "deny",
"tools": {
"get_oceanbase_cluster_zones": {}
}
}get_oceanbase_cluster_zones is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get OceanBase cluster Zone list This interface is used to query the Zone list of an OceanBase cluster. Args: cluster_id: The ID of the OceanBase cluster to query Zone list Returns: Dictionary containing Zone list and pagination information. It is categorised as a Read tool in the Mcp Oceanbase MCP Server, which means it retrieves data without modifying state.
Register the Mcp Oceanbase MCP server in PolicyLayer and add a rule for get_oceanbase_cluster_zones: 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.
get_oceanbase_cluster_zones is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_oceanbase_cluster_zones 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 get_oceanbase_cluster_zones. 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.
get_oceanbase_cluster_zones 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.
