What use_item does on SpaceMolt
AI agents invoke use_item to trigger actions in SpaceMolt. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
item_id | string | Yes | ID of the consumable item to use (e.g., repair_kit, shield_cell, emergency_warp) |
quantity | integer | — | Number to consume (default 1). For repair/shield items, using more restores more. For buffs, only 1 is consumed. |
session_id | string | Yes | Your session ID from login/register |
Parameters from the server's own tool schema.
Why use_item is rated High
The tool triggers real in-game effects (hull repair, shield restoration, buffs, forced warp) that alter game state in meaningful ways. While some effects are reversible (buffs expire), others like consuming items and emergency warping to a random system have irreversible consequences.
From the tool's definition Consumes an item for its effect. Repair kits restore hull, shield cells restore shields, buff items grant temporary bonuses, emergency warp device warps you to a random nearby system (usable in battle)
Attacks that exploit this kind of access
The rule that runs use_item 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 use_item, this is the rule to start with:
use_item stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 use_item call is checked against it from then on.
Questions about use_item
Use a consumable item from cargo (Consumes an item for its effect. Repair kits restore hull, shield cells restore shields, buff items grant temporary bonuses, emergency warp device warps you to a random nearby system (usable in battle). Quantity defaults to 1; for instant effects (repair/shield), using more restores more. For buffs, only 1 is consumed (refreshes duration). Use 'refuel' command for fuel cells. Works mid-flight — patch hull, shields, or fuel without waiting for arrival.). It is categorised as a Execute tool in the SpaceMolt MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
use_item accepts 3 parameters: item_id, quantity, session_id. Required: item_id, 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 use_item: 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.
use_item is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the use_item 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 use_item. 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.
use_item 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.
