Why search_citing_cases needs a policy

This tool retrieves citation relationships from a legal database (jade.io) without creating, modifying, or deleting any data. It is a straightforward information lookup with no side effects. The blast radius of misuse is minimal—an agent might retrieve irrelevant or excessive legal citations, but cannot corrupt data or cause material harm.

From the tool's definition Tool name 'search_citing_cases' and description 'Find cases that cite a given case' indicate a query/search operation.

POLICY

How to control search_citing_cases

PolicyLayer is an MCP gateway — it sits between your AI agents and AusLaw MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for search_citing_cases:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_citing_cases": {}
  }
}

search_citing_cases is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register AusLaw MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
