## Why batch_klines is rated Low

This tool retrieves market kline (candlestick) data in batch for financial instruments. It has no side effects, creates no data modifications, executes no code, and performs no destructive or financial transactions. It is a pure data query operation. Confidence is slightly reduced from 1.0 due to empty tool description, but the naming pattern and server context clearly indicate a read operation.

From the tool's own definition: "Tool name 'batch_klines' combined with sibling tools (batch_depths, batch_quotes, batch_ticks, single_kline, single_quote, single_tick) all indicate data retrieval operations."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call batch_klines to retrieve information from Itick without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Itick:

```json

    "batch_klines": {}
  }
