Part of the Unreal Engine MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use manage_sessions to create or modify resources in Unreal Engine. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call manage_sessions repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Unreal Engine.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Configure local multiplayer: split-screen layouts, LAN hosting/joining, voice chat channels, and push-to-talk. Required parameters by action: - configure_local_session_settings: At least one setting param required - configure_session_interface: interfaceType - configure_split_screen: enabled or splitScreenType - set_split_screen_type: splitScreenType - add_local_player: controllerId (requires PIE) - remove_local_player: playerIndex (requires PIE) - configure_lan_play: enabled, serverPort, or serverPassword - host_lan_server: mapName (requires PIE) - join_lan_server: serverAddress (requires PIE) - enable_voice_chat: voiceEnabled - configure_voice_settings: voiceSettings - set_voice_channel: channelName - mute_player: playerName or targetPlayerId - set_voice_attenuation: attenuationRadius - configure_push_to_talk: pushToTalkEnabled - get_sessions_info: No additional params required. It is categorised as a Write tool in the Unreal Engine MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for manage_sessions. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Unreal Engine MCP server.
manage_sessions 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 manage_sessions rule in your Intercept 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 Intercept policy for manage_sessions. 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.
manage_sessions is provided by the Unreal Engine MCP server (unreal-engine-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
