For self-hosted Nextcloud
Your Nextcloud knows more than its search bar lets on.
Keyword search only finds the words you remember. Astrolabe Cloud adds AI semantic search across your notes, files, and calendar — and a hosted MCP endpoint so Claude, Cursor, or any MCP client can act on it. Bring your own Nextcloud; we run the index and the server.
Bring your own Nextcloud
Connect your existing Nextcloud — we don't host your files. Your data stays where it lives.
Find by meaning, not keywords
Ask in plain language and Astrolabe surfaces the right notes, files, and events — even when they don't contain the words you typed. Results land in the Nextcloud search bar you already use.
MCP server, hosted
Plug Claude, Cursor, or any MCP client into your knowledge bank — no self-hosting.
Semantic search
Search what you meant, not just what you typed.
Astrolabe indexes your content in the background and searches it by meaning — hybrid semantic and keyword ranking — so “the contract we signed in spring” finds the right document even if it never used those words. The same index powers Nextcloud's unified search and every MCP client you connect.
- Notes, Files, Calendar, and Deck — one index.
- Hybrid ranking: semantic recall, keyword precision.
- No Qdrant, no embedders, no ops on your side.
How it works
Self-hosted Nextcloud, managed everything else.
You stay in control of your files. We run the parts that turn a Nextcloud into a searchable knowledge bank any MCP client can use.
- 01
Point us at your Nextcloud
Register an OIDC client in your Nextcloud admin app and paste the credentials. Your files stay put.
- 02
We provision the backend
A managed Astrolabe MCP server spins up on our cluster, with a per-tenant vector index and secret-managed credentials.
- 03
Connect your agent
Add the MCP URL to Claude, Cursor, or any MCP client. Search and act against your knowledge bank.
Hosted in Europe, on Hetzner.
The managed backend and your vector index run on Hetzner infrastructure in the EU — your data stays in Europe. And because you bring your own Nextcloud, your files never leave the server you already control. Sovereignty by architecture, not by promise.
EU data residency
Compute and storage on Hetzner in Germany & Finland.
Your files stay home
We index your Nextcloud — we never host or copy your files.
Per-tenant isolation
A dedicated index and secret-managed credentials per tenant.
Open source core
The Astrolabe backend is open source — inspect it, or self-host.
