Features

Feature	Description
Text-to-3D	Generate 3D model from any text description
2D Preview gate	Create image preview before expensive 3D API call
Intelligent post-processing	AI agent analyzes geometry, decides supports and orientation
Multi-view generation	Multiple camera angles → better 3D quality
Multi-object scenes	Plan and generate complex scenes with multiple objects
MCP integration	Use from Claude Desktop, Cursor, and any MCP client
Local models	Hunyuan3D-2, TripoSR, FLUX — no API costs, runs on-premise
Docker stack	Full local stack with GPU support

Intelligent Post-Processing Output

Quick Start

Option 0 — Docker image (fastest)

docker pull ghcr.io/teslaproduuction/3d-agent-mcp:latest

cp .env.example .env
# Fill in API keys

docker-compose up -d
# → http://localhost:7860

Option 1 — UV (recommended, 10–100× faster than pip)

# Install UV
winget install --id=astral-sh.uv -e        # Windows
curl -LsSf https://astral.sh/uv/install.sh | sh  # Linux/macOS

# Clone and setup
git clone https://github.com/teslaproduuction/3d-agent-mcp.git
cd 3d-agent-mcp
uv venv --python 3.10
uv sync --all-extras

# Configure
cp .env.example .env
# Edit .env with your API keys

# Run
uv run python ui/gradio_app.py
# → http://localhost:7860

Option 2 — Docker (full stack with local models)

cp .env.example .env
# Edit .env

docker-compose up -d --build
# → http://localhost

Option 3 — pip

python -m venv .venv
source .venv/bin/activate      # Linux/macOS
.venv\Scripts\activate         # Windows

pip install -r requirements.txt
cp .env.example .env
python ui/gradio_app.py        # → http://localhost:7860

MCP Integration

Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible client.

Claude Desktop config (claude_desktop_config.json)

{
  "mcpServers": {
    "3d-agent": {
      "command": "python",
      "args": ["/path/to/3d-agent-mcp/mcp_server/server.py"],
      "env": {
        "TRIPO_API_KEY": "your_key",
        "OPENAI_API_KEY": "your_key"
      }
    }
  }
}

Usage in Claude

User: Generate a phone stand for 3D printing

Claude: [calls generate_3d_model tool]
✅ Model generated and optimized for printing!
   - File: outputs/models/phone_stand_optimized.stl
   - Supports: none required
   - Orientation: base-down
   - Print time: ~2h 15min

Available MCP tools: generate_3d_model · generate_2d_preview · analyze_printability · plan_scene

→ See mcp_server/README.md for full API docs.

API Keys

Key	Purpose	Required
OPENAI_API_KEY	DALL-E 3 image gen + GPT for agents	For cloud mode
TRIPO_API_KEY	3D generation (Tripo3D cloud)	For cloud mode
ANTHROPIC_API_KEY	Claude models as agent LLM	Optional
REPLICATE_API_TOKEN	SDXL / Flux image generation	Optional

No cloud keys needed for local mode — run Hunyuan3D + FLUX via Docker stack.

Configuration

config.yaml controls all behavior:

default_settings:
  # Image generation
  image_generation:
    provider: "local"     # local | dalle3 | sdxl | flux

  # 3D generation
  generation:
    api_provider: "local" # local | tripo | meshy
    face_limit: 10000

  # Post-processing
  postprocessing:
    mode: "intelligent"   # AI decides automatically
    auto_orient: true
    max_overhang_angle: 45.0

  # Printer profile
  printer:
    build_volume: [220, 220, 250]  # mm — Ender 3 / Bambu A1
    nozzle_diameter: 0.4
    material: "PLA"

# LLM backend
llm:
  default_provider: "ollama"   # ollama | openai | anthropic
  local:
    ollama_models: ["qwen2.5:32b", "qwen2.5:7b"]

Roadmap

• Meshy API integration
• PySLM — physics-based support generation
• G-code preview before printing
• Printer preset library (Ender 3, Bambu, Prusa)
• Export to OBJ, FBX, GLTF
• REST API mode (no Gradio dependency)
