Cancel an open order by order ID. Requires authentication.
AI agents call cancel_order 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 an order is an irreversible action — once cancelled, the order is gone and cannot be reinstated. In a financial trading context, this can have significant consequences (missed trades, market exposure changes), making it Destructive in category and high in severity.

Attacks that exploit this kind of access
Cancel an open order by order ID. 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_order: 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_order 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_order 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_order. 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_order 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.
