Documented attack patterns abuse exactly the kind of access GetEarnings gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Twelve Data MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for GetEarnings:
{
"version": "1",
"default": "deny",
"tools": {
"GetEarnings": {}
}
}GetEarnings is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
