AnimAI

Production-safe 3D & motion components your AI agent can install.

AI agents are great at UI — and notoriously bad at WebGL. Ask one for a Three.js hero and you'll usually get VRAM leaks, SSR crashes, and hydration bugs. AnimAI fixes that with a registry of pre-vetted React Three Fiber & GSAP components that are certified leak-free, SSR-safe, and performance-budgeted — then injected into your Next.js app with AST-safe edits (never regex) by a CLI or an MCP server your agent calls directly.

npx animai add hero-orbital-rig

Why vetted matters

Every component ships with a machine-generated vetting report, produced by the harness in scripts/vet.mjs and enforced in CI:

Related MCP server: maige-3d-mcp

Use it from your AI agent (MCP)

Add one line to your agent's MCP config (Cursor, Claude Code, Windsurf):

{
  "mcpServers": {
    "animai": { "command": "npx", "args": ["-y", "animai", "mcp"] }
  }
}

Your agent gets two flat, deterministic tools:

• search_motion_library — natural-language search over the registry

• fetch_motion_component — exact vetted source + dependencies + integration steps

Use it from the CLI

npx animai search "dark 3d hero"        # find components
npx animai add hero-orbital-rig          # write files + AST-patch your route
npx animai add hero-orbital-rig --dry-run
npx animai add hero-orbital-rig --target main
npx animai doctor hero-orbital-rig       # check peer-dependency versions
npx animai update hero-orbital-rig       # re-fetch latest (guards your local edits)
npx animai login <license-key>           # unlock Pro components

add writes the component + SSR-safe loader into app/components/ and injects the JSX into your route using @ast-grep/napi Find & Patch — imports and nodes are inserted through the AST, so your source is never corrupted by string replacement.

Free & Pro

The CLI, MCP server, and a growing set of components are free (MIT). Pro components are delivered through a licensed registry — the public npm package and CDN never contain Pro source. See docs/registry.md.
