WHAT IT DOES

What save_multiplayer does on iDos Games

AI agents use save_multiplayer to create or update resources in iDos Games, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your iDos Games environment.

Parameter	Type	Required	Description
`value`	object	Yes	V2 definition of the title's realtime multiplayer (WebRTC signaling). Public-only data: feature switch, topology/chat defaults, limits, ICE servers.
`title_id`	string	Yes	TitleID, для которого сохраняются данные.

Parameters from the server's own tool schema.

RISK

Why save_multiplayer is rated Medium

An AI agent can call save_multiplayer faster than any human can review: one bad instruction and it creates or modifies resources in iDos Games by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs save_multiplayer safely

PolicyLayer is an MCP gateway: it sits between your AI agents and iDos Games, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For save_multiplayer, this is the rule to start with:

save_multiplayer Rate-limited

save_multiplayer 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.

FAQ

Questions about save_multiplayer

What does the save_multiplayer tool do? +

PARTIAL SAVE: writes ONLY the 'Multiplayer' field of TitlePublicConfigurationModel; all other v1/v2 fields stay untouched. Realtime multiplayer (WebRTC peer-to-peer) - the engine is only the signaling server: it creates rooms, relays WebRTC offer/answer/ICE between room members and optionally relays lobby chat; game traffic then flows directly between players' browsers and never touches the server. The section is ABSENT by default, which means multiplayer is DISABLED: add it (SystemState.Enabled = true) to turn the Multiplayer module on. DefaultTopology: Mesh (everyone connects to everyone, 2-4 players) or Host (star: every player connects to the host, which runs the authoritative game simulation - required by host-authoritative games such as VoxelCraft). MaxPlayersPerRoom is a hard cap (default 8). MemberTimeoutMs is also how long a silent host keeps the host role before another member may take it over. IceServers are PUBLIC: list only STUN servers there; short-lived TURN credentials are issued by the engine to room members on create/join. It is categorised as a Write tool in the iDos Games MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does save_multiplayer accept? +

save_multiplayer accepts 2 parameters: value, title_id. Required: value, title_id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on save_multiplayer? +

What risk level is save_multiplayer? +

save_multiplayer is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit save_multiplayer? +

How do I block save_multiplayer completely? +

Set action: deny in the PolicyLayer policy for save_multiplayer. 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.

What MCP server provides save_multiplayer? +
