Build an MLO with AI: Claude drives the interior editor

What MCP is

MCP (Model Context Protocol) is an open standard through which an AI app can use other programs' tools. Forge ships an MCP server. Connect it to Claude and Claude gets tools such as “create room”, “place prop against wall”, “check furnishing” or “build weapon pack” and calls them itself.

What Claude can do in Forge

• Interiors: paint floor plans, levels, stairs, elevators, walls and doors, lights, parking spots, peds and signs.
• Semantic placement: a shelf against a wall, a lamp on a table, lights under the ceiling.
• Search GTA templates and take them over as a project, such as a mansion or the Mission Row station.
• Convert your own OBJ models into GTA objects and place them.
• Create weapon packs, set attachments and textures, add liveries and build.
• With 5mc_forge_ingame see where you stand in game and send commands to the running game.

The MCP tools cover interiors, weapon packs, clothing packs and vehicle liveries. A detailed walkthrough with sample requests is in Build an MLO with Claude, choosing the right app in Which AI app for Forge?.

A good first request

Create a new project workshop_5mc: one ground floor, 24 by 16 metres.
At the front a reception (8 x 6 m) with a double door to the street, behind it
a hall with three car lifts (16 x 10 m) and a roller door on the east side.
Then a check image from above at an angle.

Two rounds work well: first the shell with dimensions, levels and doors, then the furnishing. That way you check the floor plan before a hundred props stand in it. That is how our Fight Arena came about: floor plan, stands and lighting via Claude, the finishing touches in the editor.
