ArtCraft MCP Server & Automation Suite

Standalone repository bundling all Model Context Protocol (MCP) server implementations, automation CLI tools, agent skills, JSON-RPC schemas, and companion bridge routes from the ArtCraft generative media platform.

This project enables AI coding assistants (Claude Desktop, Windsurf, Cursor, Antigravity, OpenClaw) to natively generate images, videos, 3D meshes, Gaussian splats, TTS, and manage media assets through natural language commands or automated scripts.

⚡ Quick Start

1. One-Click Setup (Automatic)

Run the included configuration script to auto-detect and register artcraft-mcp across Claude Desktop, Windsurf, or Cursor:

python setup_mcp.py

2. Manual Configuration

Add to your MCP client configuration file (e.g., claude_desktop_config.json or ~/.codeium/windsurf/mcp_config.json):

{
  "mcpServers": {
    "artcraft": {
      "command": "C:\\path\\to\\artcraft-mcp\\bin\\artcraft-mcp.exe",
      "args": [],
      "description": "ArtCraft AI generative media platform (Full 61-tool engine)"
    }
  }
}

---

🔑 Authentication

The server resolves credentials in the following order:

1. ARTCRAFT_MCP_PRIVATE_SESSION_TOKEN: Dedicated MCP session Bearer token (mcp_session_private_...).
2. ARTCRAFT_API_KEY: Automatically exchanged with POST /v1/mcp/session/create for an active session.
3. ARTCRAFT_SESSION and ARTCRAFT_AVT: Session cookie environment variables.
4. Credential Files: Auto-detected from ~/Artcraft/credentials/:
   • artcraft_session.txt — Your session cookie
   • artcraft_avt.txt — Your visitor cookie
5. ArtCraft Desktop App Store: Auto-detected from %LOCALAPPDATA%\ai.artcraft.app\.cookies.

🛠️ CLI Automation Suite

All scripts in tools/ communicate directly with bin/artcraft-mcp-server.exe over stdio JSON-RPC without needing external servers:

Check Credits & Generation Costs

python tools/artcraft_cost_estimator.py --check-balance --video-model seedance_2p0 --duration 5

Batch Image & Video Generation

python tools/artcraft_runner.py `
  --prompt "Cinematic cyberpunk alleyway at dusk, anamorphic lens, neon reflections" `
  --model flux_1_dev `
  --copies 2 `
  --out-dir "./outputs"

Hunyuan 3D Mesh & Gaussian Splat Generation

python tools/artcraft_3d_runner.py `
  --image "path/to/character.png" `
  --mode both `
  --out-dir "./outputs/3d"

4-Quadrant Camera Orbit Pass

python tools/artcraft_angle_matrix.py `
  --image "path/to/subject.png" `
  --prompt "Maintain facial details during camera orbit" `
  --out-dir "./outputs/orbit"

🤖 AI Agent Skills

Agent skills and prompt guidance are provided in skills/artcraft-mcp/:

• SKILL.md: Behavioral instructions, parameter schemas, and error handling for LLM agents.
• references/: Model capability tables, aspect ratio rules, and duration limits for:
  • Image: Flux 1 Dev/Schnell, Flux Pro 1.1 Ultra, Nano Banana Pro, Seedream 4/4.5/5, Midjourney 7/8.
  • Video: Kling (3.0/2.6/2.1), Veo (3/3.1), Seedance (2.0/1.5), Sora 2, Grok Imagine Video.
  • 3D & Splat: Hunyuan 3D 2.0/2.1, WorldLabs Marble Gaussian Splatting.

🖥️ Companion API Bridge

For applications integrating the MCP server as a managed subprocess, companion/mcp_routes.py provides FastAPI endpoints:

• GET /api/mcp/health — Check process state and PID.
• POST /api/mcp/start — Spawn the binary with stdio pipes.
• POST /api/mcp/stop — Gracefully terminate or kill the process.
• POST /api/mcp/token — Exchange API keys/cookies for an MCP session token.
