AI agents call list_tables 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 is a read-only operation that enumerates available tables in a database. It retrieves descriptive information without side effects, making it a Read category tool. Severity is low because listing tables poses minimal risk—it exposes only organizational metadata about publicly available Finnish statistics, not sensitive personal data or financial operations.
From the tool's definition Tool name 'list_tables' and description 'List all statistical tables within a subject area' indicates a retrieval operation with no modification, deletion, or execution capability. It browses metadata about available statistical tables.
Documented attack patterns abuse exactly the kind of access list_tables 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 list_tables:
{
"version": "1",
"default": "deny",
"tools": {
"list_tables": {}
}
}list_tables is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Tilastokeskus StatFin MCP Server MCP server in PolicyLayer and add a rule for list_tables: 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.
list_tables 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_tables 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_tables. 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_tables 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.
