Why faction_deposit_items is rated Medium
This tool transfers items between storage locations (personal to faction), which is a reversible write/transfer operation. It modifies inventory state but does not delete or destroy items. The audit log tracking suggests accountability but not irreversibility. Severity is medium because misuse could transfer valuable items to faction storage without consent, but items are not destroyed.

The rule that runs faction_deposit_items 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 faction_deposit_items, this is the rule to start with:
faction_deposit_items 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 faction_deposit_items call is checked against it from then on.
