The Connors RSI is a composite indicator combining the Relative Strength Index (RSI), the Rate of Change (ROC), and the Up/Down Length, providing a more comprehensive view of momentum and potential trend reversals.
AI agents call GetTimeSeriesCrsi 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 financial market data and returns computed technical analysis results. It is purely informational; it does not create, modify, delete, or execute any operations that would affect financial positions or external systems. The blast radius of misuse is minimal — an AI agent could only retrieve misleading technical analysis data, not perform transactions or cause data loss.
From the tool's definition GetTimeSeriesCrsi retrieves and calculates a technical indicator (Connors RSI) based on time series data. The tool name starts with 'Get' and the description indicates it provides 'a view of momentum and potential trend reversals' — a passive…

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

The Connors RSI is a composite indicator combining the Relative Strength Index (RSI), the Rate of Change (ROC), and the Up/Down Length, providing a more comprehensive view of momentum 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 GetTimeSeriesCrsi: 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.
GetTimeSeriesCrsi 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 GetTimeSeriesCrsi 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 GetTimeSeriesCrsi. 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.
GetTimeSeriesCrsi 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.
