Install paprika3D

Requirements

• Node 20.11 or later.

Claude Code

claude plugin marketplace add paprika3d/paprika3d
claude plugin install paprika3d@paprika3d

The plugin adds the game_* tools, the threejs-game skill and the hooks to Claude Code. After installing, ask the agent to build or fix a three.js page: the skill tells it to open and look at the page before saying it is done.

Other agent products

Cursor, Codex, Gemini CLI and any other client that speaks MCP run the server from npm, where it is published as paprika3d with provenance:

npx -y paprika3d serve

Register that command as a stdio MCP server in the client's configuration ("command": "npx", "args": ["-y", "paprika3d", "serve"]). For the Codex CLI: codex mcp add paprika3d -- npx -y paprika3d serve. The tools are the same; the skill and hooks are Claude Code features, so in other clients the agent needs to be told to open and look at its page (the tools page and the skill say how).
