## Why get_crypto_quote is rated Low

This tool retrieves current or historical cryptocurrency price quotes from Yahoo Finance. It performs a read-only query with no side effects—no data is modified, deleted, or financial transactions executed. The tool simply returns market data to the user, consistent with other informational tools on the server like 'get_analyst_estimates' and 'get_calendar_data'.

From the tool's own definition: "Tool name 'get_crypto_quote' and sibling tools like 'get_crypto_quote_short', 'get_crypto_price_eod', 'get_crypto_intraday' indicate data retrieval operations."

## Use case

AI agents call get_crypto_quote to retrieve information from Yahoo Finance MCP Server 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)
