AI agents call lookup_upjong_code to retrieve information from Taxlaw Nts without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple database lookup operation that retrieves and maps industry classification data. It has no side effects—it only queries existing data and returns results. No data is created, modified, deleted, or executed. The low severity reflects minimal blast radius; misuse would only return incorrect or irrelevant classification mappings without affecting tax systems or obligations.
From the tool's definition lookup_upjong_code receives a 6-digit industry code and returns mappings to KSIC classification, size category names, and codes from a database. The verb 'lookup' and 'returns' (반환합니다) indicate retrieval only.

Register the Taxlaw Nts MCP server in PolicyLayer and add a rule for lookup_upjong_code: 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 Taxlaw Nts. Nothing to install.
lookup_upjong_code 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 lookup_upjong_code 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 lookup_upjong_code. 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.
