AI agents call get_law to retrieve information from Labor Law without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a lookup/retrieval operation against a legal database. It takes a law abbreviation or name as input and returns corresponding legal provisions. There is no mention of creating, modifying, deleting, or executing operations. The blast radius of misuse is minimal—an AI agent querying incorrect provisions would simply retrieve irrelevant legal text, with no destructive or financial consequences.
From the tool's definition Tool retrieves ('取得する') specific provisions from Japanese laws using the e-Gov API. The description indicates it fetches legal text content without modification or deletion. No side effects beyond data retrieval.
Documented attack patterns abuse exactly the kind of access get_law gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Labor Law, and nothing reaches the server without passing your rules. This is the rule we recommend for get_law:
{
"version": "1",
"default": "deny",
"tools": {
"get_law": {}
}
} get_law is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

日本の法令から特定の条文を取得する。e-Gov法令API v2を使用。略称にも対応(労基法→労働基準法、安衛法→労働安全衛生法 等)。. It is categorised as a Read tool in the Labor Law MCP Server, which means it retrieves data without modifying state.
Register the Labor Law MCP server in PolicyLayer and add a rule for get_law: 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 Labor Law. Nothing to install.
get_law 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 get_law 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 get_law. 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.
get_law is provided by the Labor Law MCP server (kentaroajisaka/labor-law-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Labor Law, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
