Cancel all open orders for a subaccount. Optionally filter by currency or instrument. Requires authentication.
AI agents call cancel_all_orders to permanently remove resources in Derive MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling all open orders is an irreversible action — once orders are cancelled in a trading context, the market positions/queue priority cannot be restored. The 'all' scope makes the blast radius high, as an AI agent could inadvertently cancel every active order across all instruments for a subaccount, potentially causing significant trading disruption.

Cancel all open orders for a subaccount. Optionally filter by currency or instrument. Requires authentication. It is categorised as a Destructive tool in the Derive MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Derive MCP server in PolicyLayer and add a rule for cancel_all_orders: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Derive MCP. Nothing to install.
cancel_all_orders is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the cancel_all_orders rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for cancel_all_orders. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
cancel_all_orders is provided by the Derive MCP server (solenyaresearch0000/derive-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
