MCP Connect: How We Connected Nextcloud, Google Drive, and 1,400+ Open Datasets to Legal AI

A lawyer stores contracts in Nextcloud, correspondence in Google Drive, and searches court practice in EDRSR. Three different systems, three different windows, zero connection between them. MCP Connect unifies everything in one interface: AI analyzes your contract from Nextcloud, finds relevant practice from EDRSR, and verifies the counterparty in registries — in a single request.

MCP Connect: Nextcloud, Google Drive, and 1,400+ Open Datasets in One Interface

Your documents. Your clouds. One AI that sees everything.

The Problem: Documents Everywhere, Connection Nowhere

A typical day for a lawyer:

• Contract — in Nextcloud (or a corporate server)
• Client correspondence — in Google Drive
• Court practice — in EDRSR
• Registries — on 4 different websites
• Legislation — on the Rada website

5 systems. 5 windows. Copy-paste between them. And none of them knows the others exist.

MCP Connect: One Page — All Sources

The new MCP Connect page lets you connect external storage to LEX AI:

Nextcloud

Your self-hosted Nextcloud becomes part of the platform:

• Authorization via OAuth or app password
• Navigation through folders right in the LEX AI interface
• Document analysis — AI reads files from Nextcloud without uploading to our server
• Search across document contents via MCP tools

A law firm keeps all documents on their own server. LEX AI connects to it, analyzes a contract, identifies risks, and immediately searches for relevant practice — all in one window.

Google Drive

For those using Google Workspace:

• Connection via standard Google OAuth
• Access to documents, spreadsheets, PDFs
• The same AI analysis as for local files

1,400+ Open Datasets

Alongside MCP Connect, we added an open data catalog — pages describing all available sources:

Ukraine (ua.legal.org.ua/ua/data-sources)

| Category | Datasets | Examples | |———-|———|———| | Judiciary | 814 | Court decisions registry, hearing schedules, statistics | | Verkhovna Rada | 633 | Bills, voting records, transcripts | | Healthcare | 12 | NHSU registries, licenses | | Transport | Catalog | Vehicle registry | | data.gov.ua | 4 categories | Full open data catalog |

EU and World

• 5 EU countries — United Kingdom, Germany, France, Netherlands, Estonia
• Comparison table — eu.legal.org.ua/eu/comparison
• USA — usa.legal.org.ua/us/data-sources

What This Gives a Lawyer

Scenario 1: Contract Analysis with Context

1. AI reads the contract from your Nextcloud
2. Identifies problematic clauses
3. Searches for court practice on each risk
4. Verifies the counterparty in registries
5. Delivers a report with references to real cases

Previously, this required 4 different systems and 2 hours of work. Now — one request.

Scenario 2: Comparative Analysis

A client plans to enter the EU market. You need to compare the regulatory environment. The open data pages give direct access to official sources from 5 EU countries — with descriptions of what is available and where to look.

Scenario 3: ARMA and Seized Assets

A new dataset — the ARMA registry (Asset Recovery and Management Agency). Seized assets, confiscated property, assets placed under management. For attorneys handling criminal cases and sanctions matters — a critical source.

Architecture: Your Data Stays Yours

Key principle: LEX AI does not copy your files. The Nextcloud integration works via API — the file is read on the fly, analyzed, and the result is displayed. The original stays on your server.

For law firms, this is fundamental: clients' confidential documents never leave the corporate infrastructure.

PWA: LEX AI as an App

Bonus: LEX AI can now be installed as an app on your phone or computer. Chrome will show an "Install" button — and the platform will work as a native app with a desktop icon. Offline access to downloaded documents and instant launch without a browser.

Your documents. Your clouds. Your registries. One AI that unifies everything.
