MCP support

The stdio MCP server exposes CadCraft app tools for drawings, models, parts, takeoffs, and markups. Folder roots and read, edit, save, and export permissions can be configured.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "com-getcadcraft-studio": {
      "command": "npx",
      "args": [
        "-y",
        "@getcadcraft/mcp"
      ]
    }
  }
}
Run commandnpx -y @getcadcraft/mcp

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Details

From the project README

@getcadcraft/mcp

CadCraft's tools for AI assistants and scripts: an MCP server (cadcraft-mcp, stdio) and a command line (cadcraft). They run the CadCraft apps' own code with no window: DWG and DXF drawings (CadCraft), IFC models (BimCraft), CivilCraft sites, PartCraft parts, takeoffs (TakeoffCraft) and PDF markups (MarkupCraft). The apps contain no AI; your assistant brings its own, and you decide what it may touch. Node.js 20.19 or newer.

MCP server

npx -y @getcadcraft/mcp --root ~/Drawings --allow read,edit
  • --root <folder> (repeat for more): the only folders it opens files in and writes to. Without one, no file is reachable.
  • --allow: read (default) · edit (run commands and scripts; each call one undo step) · save (write files) · export (PDF, SVG, conversions, CSV/XLSX, LandXML, STL/3MF/STEP, OpenUSD, PartCraft manuals).
  • --log activity.jsonl: every call as a JSON line. Environment: CADCRAFT_MCP_ROOTS, CADCRAFT_MCP_ALLOW.

Connect to CadCraft Studio (the apps' windows)

npx -y @getcadcraft/mcp setup           # finds your AI apps, shows what it will write, asks first
npx -y @getcadcraft/mcp setup --list    # what it looked for
npx -y @getcadcraft/mcp unsetup         # takes CadCraft out of their settings again
npx -y @getcadcraft/mcp openapi > cadcraft-tools.openapi.json   # the same tools as an OpenAPI 3.1 description

setup adds one entry, npx -y @getcadcraft/mcp connect, to the settings of the AI apps it finds on your computer (the setup cards on getcadcraft.com/connect-ai list them). That entry holds no password; CadCraft Studio keeps its connection secret in a file only you can read, and connect reads it each time. Open CadCraft Studio, then ask your AI: "Use the CadCraft tools: list the apps you can reach." The tools are named by app (cad_…, bim_…, model_…, markup_…, takeoff_…, civil_…, detail_…, part_…); each app has its own Read / Suggest / Edit / Save / Export switches in Studio.

In your assistant's MCP settings, add it as a stdio server: {"mcpServers": {"cadcraft": {"command": "npx", "args": ["-y", "@getcadcraft/mcp", "--root", "/Users/me/Drawings"]}}}

What your assistant reads goes to whoever runs that assistant: a cloud assistant's maker sees the parts of the files it is shown. Keep folders out of --root when that matters.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
