Ways to connect

Use the hosted connector: it works with any Voidless account, free included, in Claude, ChatGPT, Claude Code, Cursor and any client that takes a URL. Every generation uses your own credits, at the same prices as the app. With Voidless+ you can also make your own API keys, for the npm package on your computer, universal-modder or your own scripts.

Hosted connector · nothing to install

Claude, ChatGPT, Claude Code, Cursor: recommended, free account

Add a custom connector with this address, then sign in to Voidless when asked:

https://mcp.voidless.dev/mcp

1. Claude (claude.ai and the Claude apps): Settings → Connectors → Add custom connector. Name it Voidless and paste the URL.
2. ChatGPT (web, paid plans): Settings → Apps & Connectors → Advanced settings → turn on Developer mode, then Create, paste the URL and pick OAuth.
3. Claude Code: claude mcp add --transport http voidless https://mcp.voidless.dev/mcp, then /mcp to sign in.
4. Cursor and other clients: add a remote (HTTP) MCP server with the URL.
5. Sign in to Voidless on the page that opens and click Allow. You're sent back to the assistant, connected.

Results show inline: images, every facing of a rotation, animations playing, and audio and video players. To disconnect, revoke its "connector" key under API keys on your account page.

npm package · runs on your computer · Voidless+

Claude Desktop, Claude Code, Codex, Cursor, VS Code

With Voidless+, create an API key on your account page, then add the server. Use this way to work with image files on your own disk. Claude Code:

claude mcp add voidless -e VOIDLESS_API_KEY=void_... -- npx -y voidless-mcp

Claude Desktop, Cursor and any client with a JSON config:

{
  "mcpServers": {
    "voidless": {
      "command": "npx",
      "args": [
        "-y",
        "voidless-mcp"
      ],
      "env": {
        "VOIDLESS_API_KEY": "void_..."
      }
    }
  }
}

Codex, in ~/.codex/config.toml:

[mcp_servers.voidless]
command = "npx"
args = ["-y", "voidless-mcp"]
env = { VOIDLESS_API_KEY = "void_..." }

Needs Node.js 18 or newer. Package: voidless-mcp.

Claude Code plugin · hosted, no API key

Claude Code, with game-art skills

The hosted connector plus skills that build a full character set (8-way turn and animation sets), make tilesets, sound effects and music, and import the result into Godot. Run these in Claude Code, then sign in when asked:

/plugin marketplace add voidless-03/voidless-mcp
/plugin install voidless@voidless

Just the connector, without the skills: claude mcp add --transport http voidless https://mcp.voidless.dev/mcp. Source: github.com/voidless-03/voidless-mcp.

universal-modder · for game modders

Modding a PC game with Claude Code

universal-modder has Voidless built in as an asset provider. Store your API key (Voidless+) once with um voidless key set, then:

um voidless sprite "a goblin scavenger with a lantern" --facing right --size 128 --style pixel-art
um voidless rotate <asset_id>
um voidless animate <asset_id> --preset platformer-character
um voidless fetch <asset_id>

Rotations give the eight facings, and every animation keeps one size with the feet on the same ground line, ready to drop into a mod.

What the assistant can do

• Your library: list and open assets, see every frame, tag assets and frames
• Images: generate a sprite or asset, upload your own, edit with an instruction, pixelate, split a character into parts
• Turns and animation: 8-way rotations, a single animation, whole animation sets from presets, mirror right-side animations to the left
• Sound and video: sound effects, music, video clips, and extending a video
• 3D: generate a model, rig it, animate it
• Free, 0 credits: slice and pack sprite sheets, export Godot SpriteFrames, make GIFs, swap palettes, add outlines

Ask in plain words, for example "make a pixel art fox, turn it to all eight directions and give it a walk". Tools that spend credits say so, and nothing is ever deleted: edits and animations are added to the asset beside what was there. The free tools cost 0 credits on any account; the AI tools use credits like the site.
