Why search_case_law needs a policy

The tool retrieves or queries legal case data from public court opinions and PACER filings. Search operations are read-only with no capability to modify, delete, or execute external actions. The sibling tools (find_cited_cases, find_citing_cases, get_*) further confirm this is a data retrieval server.

From the tool's definition Tool name 'search_case_law' and server description indicating it 'enables AI assistants to search over 4 million US court opinions' and 'access PACER federal filings through natural language' establishes this as a search/query operation with no side effects.

POLICY

How to control search_case_law

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

policy.json

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

search_case_law 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 LegalMCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
