Get a list of all available factions in the SpaceTraders game.
AI agents call List_Factions to retrieve information from SpaceTraders MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries faction data from the SpaceTraders API. It performs no modifications, deletions, code execution, or financial operations. The action is purely informational and read-only, making it a Read category tool with low severity since exposing a list of game factions poses minimal security risk.
From the tool's definition Tool name 'List_Factions' and description 'Get a list of all available factions in the SpaceTraders game' indicate a retrieval operation with no side effects.

Get a list of all available factions in the SpaceTraders game. It is categorised as a Read tool in the SpaceTraders MCP Server MCP Server, which means it retrieves data without modifying state.
Register the SpaceTraders MCP Server MCP server in PolicyLayer and add a rule for List_Factions: 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 SpaceTraders MCP Server. Nothing to install.
List_Factions is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the List_Factions 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 List_Factions. 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.
List_Factions is provided by the SpaceTraders MCP Server MCP server (thevalverde/spacetraders-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
