VibeGen MCP

Lets your AI drive a live generative art studio: read the canvas, move knobs, switch engines.

VibeGen MCP connects your AI to a running VibeGen generative art studio over the studio's HTTP API. It reads the live canvas state and every parameter, moves sliders and switches engines in real time, briefly highlights the controls it is talking about, saves, lists, reads and applies presets as JSON files, and captures a PNG snapshot of the canvas so the AI can see what it made. It can also read an engine's source (GLSL or TypeScript) and write a new version that hot-reloads into the canvas.

Point it at the hosted studio (reached through vibedna.ai/studio) or at your own instance. The art renders in the browser, on your own GPU. What the studio allows depends on your studio tier: writing engine source needs a token that the studio accepts.

Install

bash

git clone https://github.com/marstudio360/vibegen-mcp
cd vibegen-mcp
pip install -r requirements.txt

Python 3.11+.

Claude Code

bash

claude mcp add vibegen --scope user -e STUDIO_URL=http://localhost:3000 -- python /absolute/path/to/vibegen-mcp/server.py

Or in a project's .mcp.json:

json

{
  "mcpServers": {
    "vibegen": {
      "command": "python",
      "args": ["/absolute/path/to/vibegen-mcp/server.py"],
      "env": {
        "STUDIO_URL": "http://localhost:3000",
        "STUDIO_TOKEN": ""
      }
    }
  }
}

Cursor

Add the same mcpServers block to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project).

Claude Desktop

Add the same mcpServers block to claude_desktop_config.json (Settings > Developer > Edit Config), then restart Claude Desktop.

The shortest path for the hosted studio: open vibedna.ai/studio, click Set up in your AI, and drop the file it gives you into your AI chat. INSTALL.md covers the manual path step by step.

Configuration

Variable	Default	What it does
`STUDIO_URL`	`http://localhost:3000`	The studio API host to drive
`STUDIO_TOKEN`	(empty)	Sent as `x-studio-token`; needed only when the studio enforces one

To watch the changes live, open the studio with ?remote=1 (for example http://localhost:3000/?remote=1).
