Gemini How It Works
Here is what actually happens: your AI agent reads LEAP Legal matters for the billing period , client name, matter type, time entries, and billing rates.
For each client, it checks the VAT situation. EU-based client with a valid VAT number? The agent validates it through VATNode , confirms the number is active, retrieves the company name and country, and determines whether the reverse-charge mechanism applies (B2B cross-border within the EU).
Client without a VAT number? The agent retrieves the standard VAT rate for the client's country , 21% for Netherlands, 19% for Germany, 23% for Portugal, 20% for France.
The billing summary in Google Sheets shows: net amount, applicable VAT rate, VAT amount, and gross total. A German client with a valid VAT number and a Portuguese matter: reverse charge, 0% VAT, note on invoice.
A Dutch individual client: 21% BTW applied. The math is handled. The compliance is built in.
MCP Server Orchestration: 3 MCP Servers, one intelligent agent
Connect LEAP Legal, VATNode and Google Sheets MCP servers so your AI agent reads matter details and time entries from LEAP, validates the correct VAT rate for the client's EU jurisdiction through VATNode, and builds a tax-compliant billing summary in Google Sheets. European law firms handling cross-border matters , where VAT rates change by client country and service type , get invoices that are correct from the start. No manual rate lookups. No VAT errors on quarterly filings.

Superpowers you didn't know your AI had
The Vinkius catalog gives your agent access to 4,700+ MCP servers and the intelligence to combine them. Imagine never logging into another dashboard. Your AI handles the work across every tool, in one conversation. That's what this infrastructure was built for.
Cross-Platform Intelligence
Your agent doesn't just connect to tools. It understands the relationships between them. Data flows where it needs to go, automatically, with full context preserved across every platform.
Contextual Reasoning
Every decision your agent makes considers the full picture. It reads CRM data, checks calendars, reviews conversation history, and acts on everything at once. Not step by step. All at once.
Productivity at Scale
What used to take 45 minutes across five different dashboards now takes one sentence. Your agent runs the entire workflow end to end while you focus on decisions that actually matter.
Zero-Config Reliability
No API keys to paste. No webhooks to configure. No YAML to debug. Connect your MCP servers once, and your agent handles the rest. Every time, without intervention.
Made for
exactly this
Your AI agent taps into the entire Vinkius MCP catalog to handle these for you. You describe what you need. It does the rest.
European law firms handling cross-border matters who need to apply the correct VAT rate per client jurisdiction automatically
Portuguese, Dutch, German and French solo practitioners who bill international clients and need to validate VAT numbers before invoicing
Small EU law firms preparing quarterly VAT returns who waste hours reconciling billing records with tax obligations
Corporate law firms advising on EU trade matters who need fast VAT rate lookups across all 27 member states for client advisory
Frequently Asked Questions About This MCP Server Orchestration
Which MCP servers do I need for this workflow?
Three: LEAP Legal, VATNode and Google Sheets. Connect all three to your AI client before running any prompt from this page.
Does this work with Claude Desktop, Cursor or Windsurf?
Yes. Any AI client that supports the Model Context Protocol works , Claude Desktop, Cursor, Windsurf, Cline and others. Connect the MCP servers and use any prompt.
Does this handle the reverse-charge mechanism correctly?
The agent validates the VAT number, confirms the client's country, and determines whether cross-border B2B rules apply. If the client has a valid EU VAT number in a different member state, reverse charge applies at 0%. This is the standard EU rule , consult your tax advisor for specific situations.
What about UK clients after Brexit?
UK companies no longer have EU VAT numbers. The agent recognizes GB-prefix numbers as non-EU and marks the invoice as VAT-exempt. Your UK invoices follow your country's rules for non-EU service exports.
Is my financial data secure?
MCP servers authenticate through API keys or OAuth. Your agent only accesses LEAP matters, VATNode validation results and Google Sheets you have granted access to. Vinkius does not store your data.
Can I use this for non-legal EU businesses?
The LEAP Legal MCP is specific to law firms. But the VATNode + Google Sheets combination works for any EU business that needs cross-border VAT compliance. Replace LEAP with your industry-specific MCP for a similar workflow.

MCP servers used in this workflow
LEAP Legal
LEAP Legal MCP Server connects your AI client directly to LEAP Legal Software's entire database. It handles everything from creating new clients and tracking contacts to logging billable time entries, reviewing complex matters, and listing payment records. Use it when you need an agent to perform specific actions—like finding a matter ID or adding hours worked—without needing to open the main software.
VATNode
VATNode validates international VAT numbers and audits corporate data across global jurisdictions. This server lets your AI client check if a VAT ID is active, retrieve full company metadata (like names and addresses), and pull current standard or reduced tax rates for any country instantly. It handles the entire compliance workflow without manual lookups.
Google Sheets
Google Sheets MCP Server lets your AI client read, write, and manage data directly in Google Sheets. Use conversational commands to pull data from specific ranges, append new rows, or structure entire spreadsheets. It acts as an analyst, letting you manipulate complex data without opening the GUI or writing formulas.
