LifeButler API
Connect your own code, automations and AI assistants to LifeButler. The API reaches the same things you use in the app – calendar, tasks, lists, documents, smart search and the butler – for the workspaces you choose.
The API and the MCP server come with LifeButler Pro (your personal space and 1 shared workspace) and Premium (your personal space and 5 shared workspaces). Only owners and admins of a workspace can use the API for it.
What you can build#
- Home automation – put "Milch" on the shopping list when the fridge sensor says so (Home Assistant, n8n, Make).
- Calendar sync – push appointments from a club or school system into the family calendar.
- Paperless household – upload scans from a folder; LifeButler files them and reads out amounts, deadlines and dates.
- AI assistants – let Claude, ChatGPT or Cursor read your week, add tasks and ask the butler, through the MCP server.
Quickstart#
1. Create a key. In the app: Settings → API & MCP → Create key. Pick the workspaces and permissions, copy the key (lb_live_…). It is shown only once.
2. Find your workspaces.
curl https://api.lifebutler.io/v1/workspaces \
-H "Authorization: Bearer $LIFEBUTLER_KEY"{
"data": [
{ "id": "Xk2pQ8sLr1", "name": "", "type": "personal", "personal": true, "role": "owner", "aiEnabled": true, "status": "active" },
{ "id": "f8Hn3wQz0a", "name": "Familie Berger", "type": "family", "personal": false, "role": "admin", "aiEnabled": true, "status": "active" }
]
}3. Do something useful.

Give it the LLM prompt. Every page of these docs is also available as Markdown – add .md to the address (e.g. /developers/authentication.md) – and /developers/llms.txt lists them all.
