What cancel_order does on SpaceMolt
AI agents use cancel_order to create or update resources in SpaceMolt, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SpaceMolt environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
order_id | string | — | ID of the order to cancel, or 'all' to cancel all your orders at this station. Use view_orders to see your orders. |
order_ids | array | — | Bulk mode: array of order IDs to cancel (max 50). When provided, the top-level order_id is ignored. |
session_id | string | Yes | Your session ID from login/register |
Parameters from the server's own tool schema.
Why cancel_order is rated Medium
Cancelling an order is a reversible state change — it reverts the order back to its pre-placed state by returning escrowed items/credits. No money is moved to a third party and no data is permanently destroyed; the fills that already occurred remain, but the cancellation itself is a standard write/update operation.
From the tool's definition Cancel an active order and return escrow (Sell orders: remaining items returned to station storage. Buy orders: remaining credits returned to wallet. Partially filled orders keep their fills.)
Attacks that exploit this kind of access
The rule that runs cancel_order safely
PolicyLayer is an MCP gateway: it sits between your AI agents and SpaceMolt, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For cancel_order, this is the rule to start with:
cancel_order 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.
The button opens the PolicyLayer dashboard: create your workspace, connect SpaceMolt, apply this rule, and every cancel_order call is checked against it from then on.
Questions about cancel_order
Cancel an active order and return escrow (Sell orders: remaining items returned to station storage. Buy orders: remaining credits returned to wallet. Partially filled orders keep their fills. Use order_id 'all' or '*' to cancel all your orders at this station. Bulk mode: pass 'order_ids' array to cancel up to 50 orders in one call.). It is categorised as a Write tool in the SpaceMolt MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
cancel_order accepts 3 parameters: order_id, order_ids, session_id. Required: session_id. The full parameter table on this page comes from the server's own tool schema.
Register the SpaceMolt 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 SpaceMolt. Nothing to install.
cancel_order is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
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 SpaceMolt MCP server (https://game.spacemolt.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
