Why faction_invite is rated Medium
This tool creates or modifies data (faction membership) reversibly—an invitation can be declined or a player can leave the faction later—making it Write rather than Execute or Destructive. Severity is medium because misuse could spam players with unwanted invitations or manipulate faction structures, but the effects are fully reversible and localized to game mechanics without external impact or financial consequence.
From the tool's definition The tool "invite a player to your faction" creates a new membership relationship between a player and a faction.
Attacks that exploit this kind of access
The rule that runs faction_invite 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_invite, this is the rule to start with:
faction_invite 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_invite call is checked against it from then on.
