The Stochastic RSI (STOCHRSI) is an oscillator that applies the Stochastic formula to RSI values, providing a more sensitive indicator for identifying overbought or oversold conditions and potential trend reversals.
AI agents call GetTimeSeriesStochRsi 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 retrieves pre-calculated technical indicator data (Stochastic RSI oscillator values) for financial instruments. It is purely informational and analytical — it reads and returns time series data without side effects, state changes, or irreversible actions.
From the tool's definition Tool name 'GetTimeSeriesStochRsi' uses the 'Get' prefix and description states it 'provides a more sensitive indicator' — a calculation or retrieval of financial market analysis data.

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

The Stochastic RSI (STOCHRSI) is an oscillator that applies the Stochastic formula to RSI values, providing a more sensitive indicator for identifying overbought or oversold conditions and potential trend reversals. It is categorised as a Read tool in the Twelve Data MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Twelve Data MCP Server MCP server in PolicyLayer and add a rule for GetTimeSeriesStochRsi: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Twelve Data MCP Server. Nothing to install.
GetTimeSeriesStochRsi is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the GetTimeSeriesStochRsi rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for GetTimeSeriesStochRsi. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
GetTimeSeriesStochRsi is provided by the Twelve Data MCP Server MCP server (twelvedata/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
