AI agents call query_regulation to retrieve information from Mcp Taiwan Legal Db without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs retrieval operations on public legal data (court judgments, regulations, constitutional interpretations). It has no side effects—it searches, retrieves, and returns information without creating, modifying, deleting, or executing anything. The include_history parameter merely controls what data is returned in the response, not whether data is altered.
From the tool's definition The tool description explicitly states "查詢全國法規資料庫的法規條文" (query Taiwan's national legal database regulations) with parameters like law_name, article_no, from_no, to_no.
Documented attack patterns abuse exactly the kind of access query_regulation gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Taiwan Legal Db, and nothing reaches the server without passing your rules. This is the rule we recommend for query_regulation:
{
"version": "1",
"default": "deny",
"tools": {
"query_regulation": {}
}
}query_regulation is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
