AI agents call fiscal_query to retrieve information from Fiscal Api without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves Korean national fiscal data (budgets, settlements, fiscal programs) through API queries. The parameters (api_code, page_size) and description show it performs read-only operations that query existing data without creating, modifying, deleting, or executing arbitrary operations. No side effects are described beyond returning results.
From the tool's definition Tool description states '열린재정 API를 호출해 데이터를 조회합니다' (calls the open fiscal API to inquire/retrieve data). The term '조회' (retrieve/query) and parameters like 'page_size' indicate a data retrieval operation with no modification or deletion capability.

Register the Fiscal Api MCP server in PolicyLayer and add a rule for fiscal_query: 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 Fiscal Api. Nothing to install.
fiscal_query 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 fiscal_query 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 fiscal_query. 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.
fiscal_query is provided by the Fiscal Api MCP server (yangheeseok1/fiscal-api-mcp-). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
