AI agents call search_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 retrieves and queries legal documents without any side effects. It enables searching through published labor law data, which is a pure read operation. The minimal severity reflects that search results are informational only and cannot harm systems or data when misused by an AI agent.
From the tool's definition Tool performs keyword search (検索) of labor and social insurance laws (法令) using e-Gov API. The Japanese description explicitly states it searches (キーワードで検索する) laws when the law name is unknown, and returns legal texts.
Documented attack patterns abuse exactly the kind of access search_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 search_law:
{
"version": "1",
"default": "deny",
"tools": {
"search_law": {}
}
}search_law is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Labor Law MCP server in PolicyLayer and add a rule for search_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.
search_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 search_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 search_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.
search_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.
