mcp-svg-animator 0.2.1

An MCP server for creating svg animations.

MCP SVG Animator

An MCP server for creating animated SVG diagrams. You can create a diagram from text input, photos of sketches and YAML specifications.

You don't normally need to use YAML; just tell Claude code what you want, upload photos of sketches, and then iterate until you've got what you want.

You can see some sample inputs and outputs on the Demo Page

Features

• Create and iterate on your requirements using natural language and/or rough diagrams
• Multiple shape types - circle, rectangle, line, text, path, group
• Path segments - Build curves with move_to, line_to, cubic_bezier, quadratic_bezier, arc
• SMIL animations - Animate attributes and transforms
• Reusable definitions - Define once, use many times
• Library imports - Share definitions across diagrams
• Relative positioning - Reference other elements' positions
• Video export - Record animations to .webm video

Installation

pip install mcp-svg-animator

# Install Playwright browsers (for video generation)
playwright install chromium

Usage with Claude Code

Register the MCP server globally:

claude mcp add --scope user svg-animator -- python -m mcp_svg_animator

Then in any Claude Code session, ask Claude code to create animations:

"Create an animated SVG of a red circle that pulses"

See docs/usage.md for more details.

MCP Tools

You don't need to explicitly invoke these. Ask Claude code to create the animation you describe, and it will invoke the relevant tools.

Tool	Description
create_svg_from_yaml	Generate SVG from YAML specification
create_animation_video	Record SVG animation to .webm video
