Why kline needs a policy

This tool queries and retrieves historical candlestick chart data, which is a read-only operation with no side effects, data modification, code execution, or financial impact. It aligns with the Read category: retrieves or queries data without side effects.

From the tool's definition Tool retrieves 'K-line (candlestick) data for a token' — a historical price/market data query operation.

POLICY

How to control kline

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

policy.json

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

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

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
