AI agents call hyperliquid_get_funding_rates to retrieve information from Hyperliquid Funding Rates API without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though hyperliquid_get_funding_rates only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Essential for carry trade analysis, market sentiment gauging, and identifying crowded trades. Do NOT use for historical funding data -- use hyperliquid_get_funding_history instead.

It is categorised as a Read tool in the Hyperliquid Funding Rates API MCP Server, which means it retrieves data without modifying state.
