SVG Path Data Length Walker

Walk an SVG path command by command (M/L/H/V/C/S/Q/T/A/Z) — per-segment arc lengths, cumulative stroke-dashoffset distances, subpath bounding boxes, cubic handle vectors, arc flag solving, and path-vs-viewBox alignment.

MCP integration

Add this tool to your Model Context Protocol server so AI agents can list and call it.

Server configuration

Add this block to your MCP client configuration:

mcp.json

{
  "mcpServers": {
    "elysiatools-svg-path-data-cubic-quadratic-and-arc-command-length-walker": {
      "name": "svg-path-data-cubic-quadratic-and-arc-command-length-walker",
      "description": "Walk an SVG path command by command (M/L/H/V/C/S/Q/T/A/Z) — per-segment arc lengths, cumulative stroke-dashoffset distances, subpath bounding boxes, cubic handle vectors, arc flag solving, and path-vs-viewBox alignment.",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=svg-path-data-cubic-quadratic-and-arc-command-length-walker",
      "command": "",
      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "svg-path-data-cubic-quadratic-and-arc-command-length-walker",
    "arguments": {
  "pathData": "M 10 80 C 40 10, 65 10, 95 80 S 150 150, 180 80",
  "viewBox": "0 0 200 200",
  "drawPercent": 50
}
  }
}

Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
