Cadlens tools (7, 1 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • cadlens_delete_jobwrite action

    Delete a job and its uploaded file and preview image from CADLens storage. Irreversible.

  • cadlens_get_job

    Check the status of a CAD parse job. Returns PENDING, PROCESSING, COMPLETED, or FAILED.

  • cadlens_get_result

    Fetch the parsed result of a completed CAD job. Use mode='summary' (default) for an overview, 'entities_by_type' or 'entities_on_layer' for filtered detail, or 'full' for the complete vector JSON (can be very large — only use when explicitly needed).

  • cadlens_list_jobs

    List the 100 most recent CAD parse jobs for the configured API key, newest first.

  • cadlens_parse_file

    Parse a local CAD file (DWG/DXF/DWF/DWFx/DGN-V7/PDF, max 100 MB). Polls until the job completes or 5 minutes elapse. Returns a summary including the preview image URL. Use cadlens_get_result with the returned job_id to fetch detailed entity data.

  • cadlens_parse_url

    Download a CAD file from a URL (max 100 MB) and parse it. Same output as cadlens_parse_file.

  • cadlens_refresh_image_url

    Re-fetch the presigned preview-image URL for a completed job. Cheaper than re-fetching the full result. The URL is valid for 3600 seconds.

Install Cadlens in Claude Code, Cursor or VS Code

Runs npx -y @cadlens/mcp-server on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add cadlens-mcp -- npx -y @cadlens/mcp-server
Add to Cursor

What the publisher says

From the Cadlens repository's README, as published. We do not edit it. Read it on GitHub

cadlens-mcp

A Model Context Protocol server that wraps the Cadlens CAD parsing API so MCP-aware LLM clients (Claude Desktop, Claude Code, Cursor, Zed, Windsurf) can parse CAD files (.dwg, .dxf, .dwf, .dwfx, .dgn V7, .pdf, max 100 MB) and reason over the extracted entity, layer, and metadata payloads.

Cadlens converts CAD drawings into structured JSON without requiring AutoCAD or any desktop software — learn more at cadlens.co.

Install

Get an API key from the Cadlens dashboard first — keys start with cadl_ and are created in the dashboard for free.

Claude Desktop / Cursor / Windsurf

Add to your MCP client config (e.g. ~/Library/Application Support/Claude/claudedesktopconfig.json on macOS):

{
  "mcpServers": {
    "cadlens": {
      "command": "npx",
      "args": ["-y", "@cadlens/mcp-server"],
      "env": {
        "CADLENS_API_KEY": "cadl_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
      }
    }
  }
}

Claude Code CLI

claude mcp add cadlens \
  --env CADLENS_API_KEY=cadl_xxx \
  -- npx -y @cadlens/mcp-server

Development (build from source)

npm install
npm run build

export CADLENS_API_KEY="cadl_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
node dist/index.js

Tools

Configuration

Webhook short-circuit (optional)

If WEBHOOKPUBLICURL is set, parsefile / parseurl register a per-process webhook URL alongside the upload. The webhook handler updates an in-memory job-state cache; the poller checks that cache before each HTTP GET and returns early when COMPLETED / FAILED arrives. This trims worst-case latency by up to one full poll tick (~1 s) without changing the tool surface.

Example tunnel setup:

cloudflared tunnel --url http://localhost:8787 &
export WEBHOOK_PORT=8787
export WEBHOOK_PUBLIC_URL="https://<your-tunnel>.trycloudflare.com"

Development

npm run typecheck
npm run lint
npm test
npm run smoke   # tools/list smoke test against built binary
