// WHEN AI AGENTS USE THIS TOOL

AI agents use cancel_order to initiate financial transactions through OKX MCP Server. Financial operations involve real money and are irreversible once processed. Intercept blocks financial tools by default, requiring explicit human approval with transaction-level limits to prevent unauthorised spending.

// WHY ENFORCE A POLICY ON CANCEL_ORDER

cancel_order moves real money. Without a policy, an autonomous agent could initiate transactions that drain accounts or exceed budgets. Intercept blocks financial tools by default, requiring human-in-the-loop approval with configurable spending limits per transaction and per time window.

// RECOMMENDED POLICY

Financial tools involve real money. Block by default and require explicit human approval before enabling.

okx-mcp-server.yaml

tools:
  cancel_order:
    rules:
      - action: deny
        reason: "Requires human approval"
