Polymation MCP

Polymation is a multi-format animation MCP server that allows AI assistants to author, convert, and validate animation files across Rive, Spline, Lottie, Figma, After Effects, and Adobe Animate. It supports creating animations from text, converting between formats with fidelity reports, and rigging characters, running locally within Claude Desktop, Claude Code, or other MCP-compatible environments.
