Spline 3D guidance

Get Spline integration help for web and React projects.

Ask Arka for Spline integration help:

arka mcp preset spline --apply
arka spline web
arka spline react
arka spline responsive
arka spline performance
arka spline accessibility

Natural-language requests such as “how do I embed a Spline 3D model in React?” are routed automatically. Guidance covers public scene embeds, React/Next.js, responsive viewports, performance budgets, and accessible HTML fallbacks. Keep important text and controls outside the canvas so the experience remains usable when WebGL is unavailable.

MCP default

Spline MCP is Arka’s preferred provider for Spline-specific work. When a spline MCP server is configured, arka spline ... asks that server first and then includes local fallback guidance. If the server is missing or unhealthy, Arka stays useful and prints the setup command instead of inventing Spline API behavior.

arka mcp preset spline
arka mcp preset spline --apply
arka mcp tools spline

The preset uses a local spline-mcp executable if it is on PATH and passes SPLINE_API_KEY / SPLINE_WORKSPACE_ID through the MCP environment when those values are set.

If arka mcp tools spline reports MCP stdio process exited (1), run the underlying command directly:

$(python -c 'import sys; from pathlib import Path; print(Path(sys.executable).with_name("spline-mcp"))') --help

If that prints ModuleNotFoundError: spline_mcp, reinstall the Spline MCP package inside the same virtual environment that runs Arka.
