Execute a query to retrieve actual statistical data from a table. WORKFLOW: search_statistics → get_table_metadata → query_table Selection types: - filter:
AI agents call query_table to retrieve information from Tilastokeskus StatFin MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves statistical data with no side effects. Even though it 'executes a query,' the scope is strictly reading from a curated public statistics database. The filter-based selection mechanism suggests parameterized queries rather than arbitrary code execution. Misuse would at worst cause rate-limiting or temporary service disruption, not data loss or financial harm.
From the tool's definition Tool executes a query to 'retrieve actual statistical data from a table.' The verb 'retrieve' and the context of a statistics database (StatFin) indicate read-only data access.
Documented attack patterns abuse exactly the kind of access query_table gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Tilastokeskus StatFin MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for query_table:
{
"version": "1",
"default": "deny",
"tools": {
"query_table": {}
}
}query_table is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Execute a query to retrieve actual statistical data from a table. WORKFLOW: search_statistics → get_table_metadata → query_table Selection types: - filter:. It is categorised as a Read tool in the Tilastokeskus StatFin MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Tilastokeskus StatFin MCP Server MCP server in PolicyLayer and add a rule for query_table: 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 Tilastokeskus StatFin MCP Server. Nothing to install.
query_table 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 query_table 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 query_table. 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.
query_table is provided by the Tilastokeskus StatFin MCP Server MCP server (markusl/statfin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Tilastokeskus StatFin MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
