}TypeScript client, CLI, and MCP server for the Nestling baby tracking app. Read and log sleep, feed, nappy, and diary data from your Nestling account — from your terminal, a TypeScript/Bun library, or via a Model Context Protocol server for Claude, ChatGPT, and other AI assistants.
> Create-only writes. The API can log new entries that sync to your app. It cannot update or delete existing entries — your data is always safe.
Requirements
- Bun 1.3+ — the package ships TypeScript source with no build step, so it must be run on Bun (not Node).
- A Nestling account (Sign in with Google or Apple)
- A Nestling API token (generate one from the app: Settings → Data → API Token)
Install
From npm:
```bash
bun add -g nestling-ts
