KiCad PCM Server​

The --kicad-pcm flag starts a KiCad Plugin and Content Manager (PCM) server in the background alongside the development server. This allows you to install your tscircuit components directly into KiCad as a library.

tsci dev --kicad-pcm

Example output:

➜  library tsci dev --kicad-pcm
  @tscircuit/cli@0.1.851 ready in 1067ms

  ➜ Local:   http://localhost:3023/#file=lib%2Findex.ts

Watching "my-project" for changes...

  ➜ Auto-updating KiCad PCM Server: http://localhost:3023/pcm/repository.json

Adding the PCM Repository to KiCad​

To use your tscircuit components in KiCad:

  1. Open KiCad and go to Plugin and Content Manager
  2. Click Manage Repositories
  3. Click the Add button (plus icon)
  4. Enter the PCM URL shown in your terminal (e.g., http://localhost:3023/pcm/repository.json)
  5. Click OK to save

Adding the PCM repository URL in KiCad

Once added, your tscircuit library will appear in KiCad's Plugin and Content Manager. The library automatically updates as you make changes to your tscircuit project, so you can iterate on your designs without needing to re-export.
