@zeugwerk/plcsense

npm launcher for the plcsense MCP server (Windows x64).

Licence required

plcsense is commercial software (license: UNLICENSED). MCP tools stay unavailable until a valid plcsense licence is activated on the machine.

Download token required

The launcher downloads the Windows binary from api.zeugwerk.dev. Set the same token Scoop uses:

$env:PLCSENSE_TOKEN = '<your token>'

Without it, the first npx / MCP start fails before any binary is cached.

Get a licence: https://plcsense.com
Activate: plcsense license activate <licence-key>
(or pass --license-key / set PLCSENSE_LICENSE_KEY when starting MCP)

Requirements

Windows x64
Node.js 18+ (for npx)
PLCSENSE_TOKEN (download bearer token)
