Rivemcp

This gives Claude full programmatic control over Rive animation files through 139 tools that handle shapes, gradients, keyframe animation, state machines, skeletal rigging, and physics baking. You can describe a bouncing ball or an interactive button in plain English and get back a .riv file ready to drop into your app, or a .rev file to open in Rive Editor for further tweaking. It includes high-level APIs for particle systems and scene composition, plus lower-level primitives for bones, IK constraints, data binding, and nested artboards. Comes with three free exports per machine, then requires a license. Useful when you need production-ready animations generated from prompts instead of manual keyframing.
