What hent_data does on Statfin
AI agents call hent_data to retrieve information from Statfin without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why hent_data is rated Low
The tool retrieves data from an official statistics database without creating, modifying, deleting, or executing any operations. It is a straightforward data query with no side effects or destructive potential. The worst outcome of misuse would be unauthorized data access to public statistics, which is a read-level risk.
From the tool's definition Tool description states 'Fetch actual data values from a StatFin table as JSON-stat2' — a retrieval operation with no modification, deletion, or execution capability.
Attacks that exploit this kind of access
The rule that runs hent_data safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Statfin, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hent_data, this is the rule to start with:
hent_data is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Statfin, apply this rule, and every hent_data call is checked against it from then on.
