Requesting & Installing a License

TwinCat-MCP is licensed per machine. Activating it is a two-step flow: you generate a license request on the machine that will run the Service, send it to Qubernetic, and install the token you receive back.

1. Generate a license request

The request binds your future token to this specific machine.

  1. Open the Options window from the gear "Options" button on the TwinCat-MCP toolbar.
  2. Select the Licensing page.
  3. Under "1 · Generate a license request", optionally fill in Company / Email / First name / Last name — these are embedded into the token for display only.
  4. Click Generate request. The request JSON appears in the box and is also saved to:
C:\ProgramData\TwinCat-MCP\license-request.json
  1. Send that JSON (or file) to Qubernetic at info@qubernetic.com to receive your token.

Via the MCP tool

An AI agent (or any MCP client) can do the same with the always-available generate_license_request tool (optional params: company, email, first, last). It returns the request JSON and the saved path.

Note

The request is not secret — it only carries your machine identifier and the contact details you entered. You can share it freely.

2. Install your license token

Once you receive a token (a long string starting with TCMCP1.):

From the UI

  1. Options → Licensing page → "2 · Install a license token".
  2. Paste the full TCMCP1.… token.
  3. Click Install license. The result line shows either:

Via the MCP tool

Use the always-available install_license tool (param: token). It returns valid, status, and a human-readable message.

Tip

Your token is validated for this machine before anything is replaced, so a rejected token never overwrites a working license.
