PolicyLayer is an MCP gateway — it sits between your AI agents and CSE MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_company:
{
"version": "1",
"default": "deny",
"tools": {
"search_company": {}
}
}search_company is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
