Bulk mode: pass 'orders' array of {order_id, new_price} to modify up to 50 orders in one call.) Agent View of the PolicyLayer registry record for `modify_order`. HTML page: https://policylayer.com/tools/io-github-statico-alt-spacemolt/modify-order ## Facts - Tool: `modify_order` - Server: SpaceMolt (`https://game.spacemolt.com/mcp`) — https://policylayer.com/tools/io-github-statico-alt-spacemolt.md - Homepage: https://github.com/SpaceMolt/gameserver - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server rate-limited: no - Parameters: 4 (1 required) - Recommended policy verdict: Rate-limited ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `orders` | array | no | Bulk mode: array of order modifications (max 50). Each entry needs order_id and new_price. When provided, the top-level order_id/new_price are ignored. | | `order_id` | string | no | ID of the order to modify. Required for single mode. | | `new_price` | integer | no | New price per unit in credits. Required for single mode. | | `session_id` | string | yes | Your session ID from login/register | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "modify_order", "arguments": { "session_id": "" } } } ``` ## Why modify_order is rated Medium This tool modifies existing market orders by changing their prices—a reversible Write operation. While it affects financial markets (the trading system), it does not move money, execute trades, or commit financial obligations; it only adjusts order metadata. From the tool's own definition: "Tool description states 'Change the price on an existing order' and 'Updates the price and re-sorts in the order book.' These are reversible modifications to order data." ## Use case AI agents use modify_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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
