xtool-mcp

An unofficial Model Context Protocol server, agent, and llms.txt for xTool laser machines — so you can bring an xTool-savvy assistant into your design studio and the AI client of your choice.

⚠️ Unofficial & safety notice. Not affiliated with, endorsed by, or sponsored by xTool. Everything here — settings, generated .xcs files, project designs — is guidance, not a guarantee. Always test on scrap. Never cut PVC/vinyl or chlorine-containing materials. Never run a laser unattended. See DISCLAIMER.md.

What it does

• Machine knowledge — specs, work area, laser type, and supported software for the current xTool lineup (D1 family, S1, M1/M1 Ultra, F1/F1 Ultra/F2 series, P2/P3, MetalFab).

• Material settings — power/speed/passes/DPI starting points with provenance, confidence, and safety caveats — plus a "run a test grid" path when there's no good data.

• Software & troubleshooting — XCS vs Studio workflow help and symptom → cause → fix guidance.

• Design generation — produce cut-ready .xcs (and SVG): material test grids, finger-joint boxes, and SVG → .xcs conversion.

• Runs anywhere — one shared core, two entry points: a local stdio server (npx xtool-mcp) and a remote Cloudflare Worker (Streamable HTTP).

Related MCP server: OrcaSlicer MCP Server

Quick start

Use the hosted remote server

Add this Streamable HTTP endpoint to any MCP client:

https://xtool-mcp.doublexl.workers.dev/mcp

Run locally (stdio)

{
  "mcpServers": {
    "xtool": { "command": "npx", "args": ["-y", "xtool-mcp"] }
  }
}

Drop that into Claude Desktop's claude_desktop_config.json or Cursor's mcp.json (see agent/clients/), and paste agent/system-prompt.md into your client's system-prompt field for the full "xTool laser assistant" persona.

The .xcs format

.xcs is xTool's project file. It's community-reverse-engineered (plain JSON; shapes in canvas[0].displays; laser parameters in a parallel device.data Map keyed by shape id). This project generates the well-trodden single-file JSON used by D1/F1-class machines. Open generated files in Studio/XCS and verify before running. Full writeup: docs/xcs-format.md.

Development

Requires Node ≥ 18 and pnpm.

pnpm install
pnpm build            # build core + stdio
pnpm typecheck
pnpm test
pnpm start:stdio      # run the local MCP server
pnpm dev:worker       # run the Cloudflare Worker locally
pnpm build:llms       # regenerate llms.txt / llms-full.txt
pnpm build:embeddings # (optional) precompute the Workers AI search index

Architecture: docs/architecture.md · Data model & how to contribute settings: docs/data-model.md, CONTRIBUTING.md.

Deploy the Worker

cd packages/worker
pnpm dlx wrangler deploy   # deploys to xtool-mcp.<account>.workers.dev with an AI binding

The Worker also serves /llms.txt and /llms-full.txt, generated live from the knowledge base.

Contributing

Material settings especially benefit from real-world data — see CONTRIBUTING.md. Every settings row needs a source and an honest confidence level.
