Documentation Overview
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/claude_desktop_config.json on macOS):
Claude Code CLI
Development (build from source)
Tools
| Tool | What it does |
|---|---|
cadlens_parse_file | Upload a local CAD file, poll until parsed (5 min budget), return summary. |
cadlens_parse_url | Download a CAD file from a URL, then parse it like parse_file. |
cadlens_get_job | Cheap status check (PENDING / PROCESSING / COMPLETED / FAILED). |
cadlens_get_result | Fetch parsed content. mode: summary (default), entities_by_type, entities_on_layer, full. |
cadlens_refresh_image_url | Re-fetch the 1h presigned PNG URL without re-downloading the full result. |
cadlens_list_jobs | The 100 most recent jobs for the configured API key. |
cadlens_delete_job | Delete a job and its S3 artifacts. Irreversible. |
Configuration
| Env var | Required | Default | Notes |
|---|---|---|---|
CADLENS_API_KEY | yes | — | Created in the CADLens dashboard. |
CADLENS_API_BASE | no | https://api.cadlens.co/v1 | Set to http://localhost:3001/v1 for local dev. |
WEBHOOK_PORT | no | 0 (random) | Port for the in-process webhook receiver. |
WEBHOOK_PUBLIC_URL | no | unset | Set to a tunnel URL (ngrok/cloudflared) to let CADLens hit the local receiver. When set, parse calls auto-register the webhook and the poller short-circuits on receipt. |
REQUEST_TIMEOUT_MS | no | 30000 | Per-HTTP-request timeout for CADLens calls. |
Webhook short-circuit (optional)
If WEBHOOK_PUBLIC_URL is set, parse_file / parse_url 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.

Project-scoped Claude agents
This repo ships five agents under .claude/agents/:
cadlens-api-debugger— diagnoses unexplained CADLens 4xx/5xx usingmcp-server-reference.md.mcp-tool-tester— drives JSON-RPC against the built server to validate tool responses.mcp-tool-implementer— scaffolds new tools following the existingsrc/tools/*pattern.cad-drawing-summarizer— uses the MCP tools to summarize a CAD file in natural language.cad-layer-inspector— drills into a single layer of a parsed drawing.
