Readme
CADBridge MCP Server
Drive a live AutoCAD session from Claude, Codex, Cursor, and other MCP clients — create and edit entities, manage layers/blocks/layouts, run commands and AutoLISP, and capture the current view.
Requirements
- AutoCAD 2025, 2026, or 2027, with the CADBridge plugin installed and running. This npm package is the MCP server only; it talks to AutoCAD through the plugin over a local connection, and every tool call that touches AutoCAD fails with "no instance found" until the plugin is installed and AutoCAD is open.
- A CADBridge account. Signing in takes one browser click and stores no secret in your client config — see below.
Run
npx -y @dmytro-prototypes/cadbridge-mcpThe platform binary ships alongside this package, selected automatically via
optionalDependencies. The launcher installs and runs a per-user copy:
- macOS:
~/Library/Application Support/CADBridge/bin/cadbridge-mcp - Windows:
%LOCALAPPDATA%\Programs\CADBridge\cadbridge-mcp.exe
If LOCALAPPDATA is unset, Windows uses %USERPROFILE%\AppData\Local.
Later launches reuse it when its contents match the packaged binary; a different
package version replaces it atomically. The copy preserves the packaged code
signature. If Windows blocks an update because the executable is running, close
the CADBridge MCP connections in your clients and retry; the existing executable
is preserved when replacement fails.
Continue using the same npx command for startup and updates; no separate
installation command is needed.
Supported platforms are macOS Apple Silicon and Windows x64 — the platforms AutoCAD itself runs on.
Sign in
npx -y @dmytro-prototypes/cadbridge-mcp loginOpens your browser to approve the sign-in; the key is then stored in your OS
credential store, never in a config file. npx -y @dmytro-prototypes/cadbridge-mcp status
shows what's signed in, and logout forgets it. The same commands are also
available as CADBRIDGELOGIN / CADBRIDGE / CADBRIDGELOGOUT typed directly
in AutoCAD, once the plugin is installed.
Client configuration examples for Claude Desktop, Claude Code, Codex, and Cursor are at your CADBridge account's setup page.
