Voidless for coding agents

Art, animation, sound effects and music for your game, made from Claude Code, Cursor, Codex or any MCP client:

• Art: sprites, characters, props, tilesets, UI and backdrops, pixel art or painted

• Animation: 8-direction turns and whole animation sets (walk, run, attack, idle, jump, hurt, death)

• Sound: sound effects from a description (coin, jump, hit, footsteps, UI clicks)

• Music: loops of 30–120 seconds with tempo and key, for title screens, levels and battles

• 3D: models you can rig and animate

Every clip in a set keeps the same size and palette, with the feet on the same line, so it drops into a game without cleanup.

Claude Code made both knights, their idle/run/jump/attack/hurt/death clips, the swords, the backdrop and the sound through this server, then wrote the game. About $3.50 CAD of assets.

This repo has two parts:

• server/: the MCP server, published to npm as voidless-mcp and listed in the official MCP registry as dev.voidless/voidless. A hosted copy runs at https://mcp.voidless.dev/mcp.

• A Claude Code plugin: the hosted server plus skills that teach the agent how to build a full character set, make tilesets, and import the result into Godot.

You need a Voidless account. Generations spend credits from it, and each tool's description lists its cost.

Claude Code plugin

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

The first tool call opens a browser to sign in to Voidless. No API key needed.

Then ask for what you need:

• "Make a 64px pixel-art knight for a top-down game, turn it to 8 directions and give it a walk."

• "Import asset 115918 into this Godot project and set up the player."

• "Make a grass-and-dirt-path wang tileset in the same palette."

• "A coin pickup sound and a 60-second chiptune loop for the title screen."

• "Clean up this walk cycle from another tool and give me 64px pixel-art frames: ."

Other clients

Hosted (no install): add https://mcp.voidless.dev/mcp as a remote MCP server and sign in.

• Claude (claude.ai, desktop, mobile): Settings → Connectors → Add custom connector.

• Claude Code without the plugin: claude mcp add --transport http voidless https://mcp.voidless.dev/mcp

• ChatGPT: Settings → Apps & Connectors → Advanced → Developer mode → Create → OAuth.

• Cursor, VS Code, Windsurf: add it as a remote server in their MCP settings.

Local (npm): for clients that run a local server, with an API key from voidless.dev/account:

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

The full tool list is in server/README.md.

Godot import without the plugin

VOIDLESS_API_KEY=void_... node skills/godot-import/scripts/voidless-godot.mjs --asset <id> --project path/to/game

Writes res://art/<name>/<clip>/NN.png and res://art/<name>/<name>.tres, with one animation per clip (walk_down, walk_down_right, attack_1…) and an idle_<facing> frame for each turn image. Tested with Godot 4.7.
