KerfScript MCP sunucusu

KerfScript MCP

An MCP server that lets AI assistants write and check KerfScript laser-cutting designs. The assistant can read the KerfScript docs and examples, find a design's settings and render it to SVG or DXF, so it can test its code before giving it to you.

Connect

The hosted server needs no account or key:

https://mcp.mylasertools.com/mcp

Claude Code

claude mcp add --transport http kerfscript https://mcp.mylasertools.com/mcp

Claude (desktop and web): Settings → Connectors → Add custom connector, and enter the address above.

Cursor: add it to .cursor/mcp.json:

{
  "mcpServers": {
    "kerfscript": { "url": "https://mcp.mylasertools.com/mcp" }
  }
}

VS Code: add it to .vscode/mcp.json:

{
  "servers": {
    "kerfscript": { "type": "http", "url": "https://mcp.mylasertools.com/mcp" }
  }
}

Run it locally

With Node.js 20 or newer, the same server runs on your computer and designs never leave it:

{
  "mcpServers": {
    "kerfscript": { "command": "npx", "args": ["-y", "@mylasertools/kerfscript-mcp"] }
  }
}

In Claude Code:

claude mcp add kerfscript -- npx -y @mylasertools/kerfscript-mcp

Tools

Tool	What it does
kerfscript_docs	Reads the guides and the language reference
kerfscript_examples	Finds examples by title or tag and returns their source
kerfscript_parameters	Lists a design's settings with their ranges and choices
kerfscript_render	Renders a design to SVG or DXF, with its parts, sizes, layers and any warnings

Sizes are in millimetres. Text uses the bundled Atkinson Hyperlegible font.

Limits

A design may be up to 64,000 characters, with up to 20 libraries of its own passed alongside it. It cannot read files or fetch anything from the network. Each render stops at 100,000 steps, 100 parts and 10 sheets. For bigger designs or other fonts, use the KerfScript package or its command line.

The hosted server allows each client about 60 requests a minute and 1,000 a day. It does not store or log the designs you send.

A render that succeeds does not mean the parts fit. Cut a test piece in your material before cutting a new design.
