While the server overall contains Financial tools (as evidenced by sibling tools for trading and payments), this particular tool does not move money, execute trades, or modify state—it only queries market data.

From the tool's definition Tool retrieves candlestick data ('Get...kline'), described as 'funding rate basis' information used for 'calculate funding payments' — a historical data query with no side effects, no state modification, and no execution capability.

How to control get_premium_index_price_kline

PolicyLayer is an MCP gateway — it sits between your AI agents and Bybit MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_premium_index_price_kline:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_premium_index_price_kline": {}
  }
}

get_premium_index_price_kline is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
