Returns trading information performed by insiders.
AI agents call GetInsiderTransactions to retrieve information from Twelve Data MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves historical insider trading data. It is a read-only operation that accesses financial market data without side effects. While the data concerns insider transactions (which are sensitive market information), the tool itself only performs data retrieval. There is no capability to execute trades, modify data, delete records, or commit financial transactions.
From the tool's definition Tool name is 'GetInsiderTransactions' and description states it 'Returns trading information performed by insiders' — a retrieval operation with no modification, deletion, or execution capabilities.

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 GetInsiderTransactions:
{
"version": "1",
"default": "deny",
"tools": {
"GetInsiderTransactions": {}
}
}GetInsiderTransactions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
