Why get_cached_citation needs a policy

This tool only retrieves pre-existing cached citation data and performs no modifications, deletions, or external operations. It is a pure read operation with minimal blast radius - worst case, an agent retrieves incorrect or sensitive legal citations, but cannot modify data, execute code, or cause financial harm.

From the tool's definition Tool description states it 'Retrieve[s] a citation from the local cache' - a retrieval operation with 'no network calls'. The lookup parameters (cite key, AGLC4 string, neutral citation, case title) are all read-only queries against cached data.

POLICY

How to control get_cached_citation

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 get_cached_citation:

policy.json

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

get_cached_citation 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.
