What it can do

Tool names and descriptions exactly as the server reported them on Nov 13, 2026. The maker wrote them, not us; we show them as plain text.

kerfscript_docs
Read KerfScript language and JavaScript integration documentation for building laser-cutting generators. Omit topic to list guides. Long guides are paginated with nextOffset.
kerfscript_examples
Find working parametric laser-cutting examples by title, id or tags. Supply an id from the results to get its .kerf source.
kerfscript_parameters
Extract editable settings and customizer ranges from .kerf source to build a generator UI. Parses without rendering geometry.
kerfscript_render
Render .kerf source to SVG or DXF files, one per sheet, with part sizes, layers and warnings. Uses millimetres and bundled Atkinson font. No filesystem or network imports. Bounded to 100 parts and 10 sheets. For production generators install @mylasertools/kerfscript locally.

Common questions

Is KerfScript safe?

It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed 3 days ago, and the latest version (0.1.1) reached the registry 12 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

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.
