Cancel spot order(s): single order or all orders for a symbol.
AI agents call cancel_spot_order to permanently remove resources in Asterdex — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling orders is irreversible — once an order is cancelled, it cannot be restored. This can have significant financial impact if active trading orders (including protective or profit-taking orders) are cancelled, potentially exposing positions to unintended market risk. The ability to cancel 'all orders for a symbol' amplifies the blast radius considerably.
From the tool's definition Cancel spot order(s): single order or all orders for a symbol.

Cancel spot order(s): single order or all orders for a symbol. It is categorised as a Destructive tool in the Asterdex MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Asterdex MCP server in PolicyLayer and add a rule for cancel_spot_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 Asterdex. Nothing to install.
cancel_spot_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_spot_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_spot_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.
