What the server does

  • devTeamdeprecated
  • iPhoneDeploymentTarget — optional
  • smallIcons — optional
  • largeIcons — optional

Installation

Where it fits

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Onesignal's toolset — Website, Twitter, Github and 11 more — is a fair guide to whether it matches your workflow. It is maintained by GitHub Actions; worth a glance at recent repository activity before you build anything load-bearing on it.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Onesignal.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
