Spline MCP Server
Spline MCP server enabling AI agents to interact with Spline — the popular browser-based 3D design tool used for creating interactive 3D web experiences, animations, and design assets. Enables reading scene state, modifying 3D objects and animations, managing Spline projects, and integrating 3D design capabilities into agent-driven creative workflows.

HTTPS. API key. Cloud-hosted 3D scenes. Free tier scenes may be public. Use Pro plan for private commercial design work.
⚡ Reliability
Best When
A developer or designer using Spline for interactive web 3D needs AI assistance creating and modifying scenes — Spline is popular for landing pages, product visualizations, and interactive web experiences.
Avoid When
You need professional 3D production capabilities — Spline is for web-focused interactive 3D, not production-grade 3D modeling.
Use Cases
- • Creating and modifying 3D scenes and objects from design automation agents
- • Animating 3D elements and interactions from creative workflow agents
- • Exporting 3D assets and code from Spline for web integration from development agents
- • Managing Spline design project files from creative coordination agents
- • Generating 3D visual content for web applications from full-stack development agents
Not For
- • Complex 3D production workflows (use Blender, Maya, or Cinema 4D MCPs for professional 3D)
- • CAD and engineering 3D work (Spline is for interactive web 3D, not precision engineering)
- • Teams not using Spline for 3D design
Interface
Authentication
Spline API key required. Generate from Spline account settings. Set SPLINE_API_KEY environment variable. Spline account (free tier available) required.
Pricing
