Installation

HullForge has two halves and you need both: an Unreal plugin that does the work, and a connector that lets Claude reach it. This is the same shape as most editor integrations.

Requirements

Thing	Why
Unreal Engine 5.8	The plugin runs inside the editor
Windows 64-bit	The only platform currently built
Claude Desktop	Hosts the connector

1. Install the Unreal plugin

Copy the HullForge folder into your project’s Plugins directory, so you end up with:

YourProject/
  Plugins/
    HullForge/
      HullForge.uplugin
      Source/

Open the project, then enable it under Edit > Plugins > Editor. Restart when prompted.

On restart, HullForge begins listening on loopback automatically. Nothing else to configure.

2. Install the Claude connector

Double-click HullForge.mcpb, or drag it onto Claude Desktop.

That is the whole installation. There is no JSON to edit and no Python to install: the connector is a single self-contained file.

3. Check it worked

Open your Unreal project, then ask Claude:

Is HullForge connected?

You should get back the project name and a tool count.

If no editor is running you will see only one tool, hf_bridge_status, and it will tell you what to do. That tool is deliberately always available so that “nothing is here” is never a silent state.

Nothing appeared

If Claude lists no HullForge tools at all, the connector did not install. Check Claude Desktop’s connector settings.

If it lists only hf_bridge_status, the connector is fine and the editor is the problem. Either no project is open, or the plugin is not enabled in the one that is. Open the project and the remaining tools appear within a second or two, with no need to restart Claude.
