aggregate_statistics
AI agents call aggregate_statistics to retrieve information from Korean Stat without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on the server's purpose and naming pattern of sibling tools, this tool likely performs read-only aggregation operations on statistical data. While the description is empty, the context strongly suggests a data retrieval/analysis function rather than write, execute, or destructive operation.
From the tool's definition Tool is part of a server that 'search, retrieve, and analyze Korean statistical data' with sibling tools named get_statistics_data, get_table_metadata, and filter_statistics.
Attacks that exploit this kind of access
aggregate_statistics. It is categorised as a Read tool in the Korean Stat MCP Server, which means it retrieves data without modifying state.
Register the Korean Stat MCP server in PolicyLayer and add a rule for aggregate_statistics: 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 Korean Stat. Nothing to install.
aggregate_statistics 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 aggregate_statistics 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 aggregate_statistics. 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.
aggregate_statistics is provided by the Korean Stat MCP server (seolcoding/korean-stat-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
