AI agents call list_backup_policies 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.
The tool retrieves information about backup policies without side effects. Although the description is empty, the function name clearly indicates a read-only operation that queries existing backup policy configurations. No write, execute, or destructive capability is evident. Severity is low because listing policies reveals administrative configuration but does not affect data or systems directly.
From the tool's definition Tool name 'list_backup_policies' indicates listing/querying backup policies; no parameters provided to modify or delete policies. The 'list' verb is a standard read operation.
Documented attack patterns abuse exactly the kind of access list_backup_policies 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 list_backup_policies:
{
"version": "1",
"default": "deny",
"tools": {
"list_backup_policies": {}
}
}list_backup_policies is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_backup_policies. 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 list_backup_policies: 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.
list_backup_policies 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 list_backup_policies 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 list_backup_policies. 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.
list_backup_policies 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.
