Installation

Requirements

Unreal Engine	5.8.0 or later
Platform	Windows 64-bit only
Windows version	Windows 10 build 18362 (version 1903) or later — required for ConPTY
For WSL shells	Windows 10 build 19041 (version 2004) or later
Required plugins	ToolsetRegistry and ModelContextProtocol (both ship with UE 5.8)
Optional	psmux or tmux, for persistent multiplexed workspaces

Windows only, for now

Conductor Terminal declares Win64 as its only supported target platform. If you enable it on a Linux or macOS editor it will not load. Cross-platform support is planned, not shipped.

Install the plugin

From Fab

Install Conductor Terminal to your engine version from the Epic Games Launcher, then enable it in your project. The launcher places it under <EngineRoot>/Engine/Plugins/Marketplace/ConductorTerminal.

From a zip

1. Close the Unreal Editor.

2. Unzip ConductorTerminal_5.8.zip so that ConductorTerminal.uplugin ends up at:

   <YourProject>/Plugins/ConductorTerminal/ConductorTerminal.uplugin

   Create the Plugins folder if your project does not have one.

3. Reopen the project. If prompted to rebuild modules, accept.

Verify it loaded

Open Edit → Plugins and search for Conductor Terminal. It should appear under Developer Tools, enabled, version 1.0.0, by Reality Shift LLC.

Enable the MCP dependencies

Conductor Terminal’s agent features are built on Epic’s own MCP stack. Two engine plugins have to be enabled:

• Model Context Protocol — the local MCP server the editor exposes.
• Toolset Registry — the registry the plugin publishes its agent tools into.

Both are listed as dependencies in the .uplugin, so enabling Conductor Terminal normally enables them for you. The plugin’s settings page — Edit → Editor Preferences → Plugins → Conductor Terminal — carries a readiness section under Unreal MCP Client Config that runs three checks and offers a Fix button for each one that fails:

Check	What it means	What Fix does
MCP plugin enabled	ModelContextProtocol is on in the project.	Enables the plugin in your .uproject. Needs an editor restart.
Auto Start Server	The MCP server starts with the editor rather than waiting to be started by hand.	Turns the option on in your editor preferences. Takes effect on the next editor launch.
Toolsets enabled	Epic’s toolset plugins (the AllToolsets aggregator) are on, so the agent gets the full editor surface and not just Conductor Terminal’s tools. The row shows N/M enabled.	Enables the AllToolsets plugin in your .uproject. Needs an editor restart.

Note

Enabling an engine plugin writes to your .uproject and needs an editor restart to take effect. The Fix buttons save the change for you, but they cannot skip the restart.

Server address

On UE 5.8+ the editor’s MCP server is configured under Edit → Editor Preferences → Plugins → Model Context Protocol:

Setting	Default
Server Port Number	8000
Server URL Path	/mcp

Which gives an endpoint of http://127.0.0.1:8000/mcp. Conductor Terminal reads these two values rather than assuming them, so if you change the port the generated agent configs follow.

First run

Open the terminal from Tools → Conductor Terminal → Conductor Terminal 1, press Alt+F2, or click the Conductor Terminal button in the editor’s status bar to flick open the drawer. You should get a PowerShell prompt in your project directory.

If you get a blank pane or an error instead, head to Troubleshooting.

Optional: install psmux

psmux is a Windows-native, PowerShell-based terminal multiplexer. It is not bundled and the plugin will never install it for you. You only need it if you want PSMux Workspace mode, where shells keep running in the background and survive an editor restart.

winget install marlocarlo.psmux

Or download it from github.com/psmux/psmux. If you prefer to work inside WSL, tmux inside the distribution does the same job.

The plugin finds psmux through PATH and where.exe — there is no sweep of install folders, so if you installed it somewhere unusual, add that folder to your PATH. Detection runs once per editor process, so after installing psmux restart the editor to pick it up.
