## Why ccxt_fetch_binance_open_interest_hist is rated Low

This tool retrieves historical open interest data from Binance futures markets. The 'fetch' verb and the endpoint name (fapiDataGetOpenInterestHist) indicate a read-only query operation with no side effects. It neither modifies data, executes code, deletes information, nor commits financial transactions. The blast radius of misuse is minimal—an agent could only retrieve market data that is publicly available.

From the tool's own definition: "Tool name contains 'fetch' and description indicates it calls a data retrieval endpoint (fapiDataGetOpenInterestHist) that returns historical open interest data without modifying state."

## Use case

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