AI agents use deposit_items to initiate financial transactions through SpaceMolt. Financial operations involve real money and are irreversible once processed. PolicyLayer blocks financial tools by default, requiring explicit human approval with transaction-level limits to prevent unauthorised spending.
deposit_items moves real money. Without a policy, an autonomous agent could initiate transactions that drain accounts or exceed budgets. PolicyLayer blocks financial tools by default, requiring human-in-the-loop approval with configurable spending limits per transaction and per time window.

Move items from cargo (or directly from personal/faction storage) into a storage destination (Items default to moving from cargo into your personal station storage. Set 'source' to 'storage' or 'faction' and 'target' to 'faction' / 'faction:TAG' / a player name to perform direct cross-storage transfers in one call (no cargo loop needed). Must be docked at a base with storage service.). It is categorised as a Financial tool in the SpaceMolt MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
Register the SpaceMolt MCP server in PolicyLayer and add a rule for deposit_items: 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.
deposit_items is a Financial 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 deposit_items 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 deposit_items. 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.
deposit_items 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.
