Context Cost

~802Tokens (tool definitions)
~1.4 KBTypical response size
Moderate attention impact (0.63% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

}
🟢kerfscript_parameters(source)

Extract editable settings and customizer ranges from .kerf source to build a generator UI. Parses without rendering geometry.

{
  "type": "object",
  "properties": {
    "source": {
      "type": "string",

  "additionalProperties": false
}
🟢kerfscript_render(source, params, libraries, format, sheet, ...)

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.
