创建、编辑、检查、渲染并实时预览Claude的Rive（.riv）动画——无需Rive编辑器，无需云端，无需订阅。

日本語 README 是こちら

rive-mcp 是一个免费的 MCP（模型上下文协议）服务器，允许 Claude（或任何 MCP 客户端）完全控制 [.riv 文件。与官方 Rive MCP（需要运行编辑器）或付费第三方服务器不同，它仅使用 .riv 文件——甚至可以直接序列化二进制格式，**从零构建 .riv]文件。

渲染在无头铬中运行官方Rive运行时（@rive-app/canvas-advanced] WASM），所以你看到的正是发布内容。

这部动画完全由riv_create生成——没有Rive的剪辑师参与。

精彩片段

• **从 JSON 生成 .riv ——形状、渐变、嵌入的 PNG、文本、骨骼 + 蒙皮、IK、网格变形、带简化的关键帧动画、多层状态机、监听器、事件、物理烘焙、粒子、从时间线或状态机触发的嵌入音频（WAV/MP3/FLAC）

rive-mcp

Create, edit, inspect, render and live-preview Rive (.riv) animations from Claude — no Rive editor and no subscription. The server runs on your machine; the few outside calls are listed under Network access.

rive-mcp is a free MCP (Model Context Protocol) server that gives Claude (or any MCP client) full control over .riv files. Unlike the official Rive MCP (which requires the editor running) or paid third-party servers, it works with nothing but a .riv file — and it can even build .riv files from scratch by serializing the binary format directly.

Rendering runs the official Rive runtime (@rive-app/canvas-advanced WASM) inside headless Chromium, so previews follow the runtime’s output, except for the Canvas2D differences listed under Limitations.

This animation was generated entirely by riv_create — no Rive editor involved.

Highlights

• Generate .riv from JSON — shapes, gradients, embedded PNGs, text (including text on path), bones + skinning, IK, mesh deformation, keyframe animation with easing, multi-layer state machines, listeners, events, physics baking, particles, embedded audio (WAV/MP3/FLAC) fired from the timeline or a state machine
• Pro-quality by construction — 28 semantic motion presets (pop-in, staggered rise-in, breathing, stagger-in, parallax-drift, shimmer, …) with professionally tuned amplitudes/easings, an OKLCH design-token generator (riv_design_tokens), motion-quality lint rules (robotic linear movement, teleports, missing stagger), and a one-call critique loop (riv_critique: frames + objective metrics + scoring checklist)
