AI + MCP Access
Give agents controlled access to your data without copy-pasting your life into chat windows.
Local-first database for user-owned software
Your data
is not
their moat.
EweserDB is a local-first interoperable database for apps that refuse lock-in. Notes, agents, study tools, publishing workflows, and collaborative workspaces can all connect to the same user-owned data.
User Auth
MCP Access
Personal Data
Connected Apps
Apps became landlords.
Modern software treats your notes, decisions, documents, and knowledge like platform property.
The old world
- Your work gets trapped in product-specific databases
- Switching tools means rebuilding context from scratch
- Collaboration requires everyone to join the same silo
- AI agents cannot help unless your data is accessible
EweserDB world
- You own the database
- Apps compete to serve you
- Offline first. Always available. Always yours.
- AI agents plug into user space through scoped MCP access
"Own the substrate. Swap the interface."
A bigger playground for your data.
Notes are one proof point. The larger story is one user-owned data layer feeding AI tools, collaborative workspaces, study flows, publishing workflows, and team memory.
02
Collaborative Notes
Work together in real time with offline-first sync and conflict-free CRDT merging.
03
Knowledge Base
Keep structured notes, links, and documents in a system other apps can understand.
04
Study Tools
Turn notes into flashcards, summaries, and spaced repetition flows without export gymnastics.
05
Publishing
Reuse the same data across sites, docs, newsletters, and knowledge portals.
06
Team Memory
Share decisions, references, and working knowledge without locking the team into one interface forever.
04 // Connected Tools
Let apps and agents ask permission.
The landing page should preview the actual product: entry, ownership, permissions, and agent access.
User-owned auth
Sign in, approve scopes, and keep trust visible.
Personal data
Collections, schemas, rooms, sync, sharing, and storage.
Connected apps
Installed tools, granted access, recent usage, and revoke controls.
MCP / AI access
Clients, permissions, metadata, audit-style visibility, and setup.
For Developers
Build the app. Not the prison.
Add @eweser/db to your app. Shared schemas, CRDT sync, and MCP-ready access patterns give builders useful software without another proprietary island.
Terminal
$ npm install @eweser/db yjs app.ts
import { Database } from '@eweser/db';
const db = new Database({
initialRooms: [{ collectionKey: 'notes', name: 'My Notes' }]
});
const room = db.getRoom('notes');
const Notes = room.getDocuments();
Notes.new({ text: 'Hello from any app' });Type-safe schemas
Strongly typed collections, documents, and _ref links keep interop practical instead of theoretical.
Real-time CRDT sync
IndexedDB locally, Yjs for conflict-free collaboration, and Hocuspocus for live transport.
MCP-ready access
Connect Claude Desktop, ChatGPT, or your own agent workflows through scoped MCP access.
No prison backend
Point apps at eweser.com or a self-hosted homeserver without inventing another proprietary island.
Shared app interop
Build against shared schemas when you want ecosystem compatibility, or extend with private models.
Self-hostable stack
Own the infra, run your own auth and sync services, and stay independent of anyone else’s moat.
