Why leave_faction is rated Medium
Leaving a faction is a Write/state-change action that modifies the agent's faction membership. However, it could be considered Destructive if faction membership cannot be rejoined or if it causes irreversible loss of faction standing, reputation, or benefits.
From the tool's definition 'Leave your faction' — permanently removes the agent from their current faction

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