configure_network
Configure lobby settings on Sandbox.Networking. Currently only lobbyName is applied (sets Networking.ServerName) — Networking.MaxPlayers is read-only on this SDK, and playerPrefab/startServer are not applied by the handler (use add_network_helper + set_prefab_ref for those). Returns { configured,...

What configure_network does on Sbox
AI agents use configure_network to create or update resources in Sbox, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sbox environment.
Why configure_network is rated Medium
Modifies game network configuration reversibly; affects multiplayer lobby visibility and connectivity settings.
From the tool's definition Configure lobby settings; sets Networking.ServerName; live Networking values
Attacks that exploit this kind of access
The rule that runs configure_network safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Sbox, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For configure_network, this is the rule to start with:
configure_network 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 Sbox, apply this rule, and every configure_network call is checked against it from then on.
Questions about configure_network
Configure lobby settings on Sandbox.Networking. Currently only lobbyName is applied (sets Networking.ServerName) — Networking.MaxPlayers is read-only on this SDK, and playerPrefab/startServer are not applied by the handler (use add_network_helper + set_prefab_ref for those). Returns { configured, maxPlayers, serverName } reflecting the live Networking values. It is categorised as a Write tool in the Sbox MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sbox MCP server in PolicyLayer and add a rule for configure_network: 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 Sbox. Nothing to install.
configure_network is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the configure_network 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 configure_network. 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.
configure_network is provided by the Sbox MCP server (sbox-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
