## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-04.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 403, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 59/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 381 tokens (~95/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 13% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Install

### How do I install the KerfScript MCP server?

KerfScript is a hosted endpoint at https://mcp.mylasertools.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

  }
}
```

### VS Code

      "enabled": true
    }
  }
}
```

### OpenClaw

```bash
openclaw mcp add com-mylasertools-kerfscript --url 'https://mcp.mylasertools.com/mcp' --transport streamable-http
```

### Hermes

```yaml
mcp_servers:
  com-mylasertools-kerfscript:
    url: "https://mcp.mylasertools.com/mcp"

      "Transport": "http",
      "Url": "https://mcp.mylasertools.com/mcp"
    }
  }
}
```

### Vellum

```bash
assistant mcp add com-mylasertools-kerfscript -t streamable-http -u 'https://mcp.mylasertools.com/mcp'
```

### Other

```json
{
  "mcpServers": {

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

The mcpServers block is a cross-client convention. Remote transports vary, so check your client's docs.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-04 (score 63, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-11-02 (score 62, 0)

- [functional improvement] Stability: unverified → 0.03

### 2026-11-01 (score 62)

First indexed and scored.

## MCP tools (4)

### `kerfscript_docs` (~57 tokens)

Read KerfScript language and JavaScript integration documentation for building laser-cutting generators. Omit topic to list guides. Long guides are paginated with nextOffset.

Input parameters:

- `offset` (integer)
- `topic` (string)

### `kerfscript_examples` (~60 tokens)

Find working parametric laser-cutting examples by title, id or tags. Supply an id from the results to get its .kerf source.

Input parameters:

- `id` (string)
- `offset` (integer)
- `query` (string)

### `kerfscript_parameters` (~40 tokens)

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

Input parameters:

- `source` (string, required)

### `kerfscript_render` (~172 tokens)

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.

Input parameters:

- `format` (string)
- `gap` (number)
- `kerf` (number)
- `layout` (string)
- `libraries` (object): Optional virtual libraries keyed by the exact use/include path. No files or URLs are fetched.
- `margin` (number)
- `params` (object)

## Common questions

### What is the KerfScript MCP server?

KerfScript is an MCP server listed in the public MCP registry as com.mylasertools/kerfscript. Write, check and render parametric laser-cutting designs in KerfScript, as SVG or DXF. This page covers its hosted endpoint (https://mcp.mylasertools.com/mcp).

### Is the KerfScript MCP server safe to use?

KerfScript scores 63 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the KerfScript MCP server expose?

KerfScript exposes 4 tools: kerfscript_docs, kerfscript_examples, kerfscript_parameters, kerfscript_render. Their descriptions and schemas cost roughly 329 tokens of context every time the server is loaded.

### Does the KerfScript MCP server require authentication?

No. We connected to KerfScript without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the KerfScript MCP server still maintained?

KerfScript is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
