Why spotMarginSetLeverage needs a policy

This tool modifies account trading parameters (leverage settings) reversibly through the Bybit API. While not destructive or financial in itself, setting leverage is a Write action that reconfigures account state and materially affects the risk profile of subsequent trades.

From the tool's definition Tool description states 'Set the maximum leverage for spot cross margin trading' — the word 'Set' indicates modification of account configuration. The leverage setting directly affects trading constraints and risk exposure on the account.

POLICY

How to control spotMarginSetLeverage

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 spotMarginSetLeverage:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "spotMarginSetLeverage": {
      "limits": [
        {
          "counter": "spotmarginsetleverage_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

spotMarginSetLeverage stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Bybit MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
