AI agents call get_current_time 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 queries and retrieves the current time from a database. It performs a read-only operation with no ability to modify, delete, or execute code. The blast radius is minimal as it only returns a timestamp value. No financial, destructive, or executable operations are possible.
From the tool's definition Tool name 'get_current_time' and description 'Get current time from seekdb database' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_current_time 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_current_time:
{
"version": "1",
"default": "deny",
"tools": {
"get_current_time": {}
}
}get_current_time is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get current time from seekdb database. 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_current_time: 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_current_time 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_current_time 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_current_time. 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_current_time 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.
