The Ichimoku Cloud (ICHIMOKU) is a comprehensive trend-following indicator that combines multiple moving averages and support/resistance levels to help traders identify potential entry and exit points, trend direction, and momentum.
AI agents call GetTimeSeriesIchimoku 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.
GetTimeSeriesIchimoku is a data retrieval function that calculates and returns technical indicator values from market data. It performs no mutations, financial transactions, destructive operations, or external executions.
From the tool's definition Tool retrieves financial market data (Ichimoku Cloud indicator values derived from time series) with no side effects. Description states it 'helps traders identify' trends, indicating analysis and retrieval rather than modification or execution.

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