FacturaHub

Introduction to FacturaHub

FacturaHub is an MCP (Model Context Protocol) server that provides financial memory capabilities for AI agents. It integrates with AI assistants such as Claude and Cursor, enabling users to manage core financial operations—including invoicing, expense tracking, tax calculations, and financial reporting—using natural language commands. The system eliminates the need for traditional dashboards, forms, or dedicated applications, instead leveraging conversational interaction as the primary interface.

Designed specifically for freelancers and agencies already using Claude or Cursor in their daily workflows, FacturaHub supports financial operations across more than 20 countries with region-specific tax rules, including automatic VAT/IVA and income tax (e.g., IRPF) calculations. All data is encrypted, and user accounts are configured without requiring credit card information.

Key Takeaways

• Create, send, and track invoices via natural language prompts to Claude or Cursor
• Register expenses by category (e.g., software, hosting, travel, office) and associate them with financial reports
• Generate automated Profit & Loss statements, cash flow projections, and tax-ready summaries
• Calculate VAT/IVA liability (collected vs. paid) per quarter and determine fiscal credit or debt status
• Produce professional PDF invoices with configurable bank details (IBAN, SWIFT) and support for recurring billing
• Configure company profile, tax information, and banking data either through the AI interface or web dashboard
• Supports multi-user access (Pro plan) and scales from free tier (5 invoices/month) to unlimited usage

How FacturaHub Works

FacturaHub operates as a backend service that connects to AI assistants via the Model Context Protocol. After registration and onboarding—completed in under two minutes—the user obtains an API key and installs the FacturaHub MCP plugin in Claude Desktop or Cursor with a single command. Once connected, the AI agent gains contextual awareness of the user’s financial setup (company details, currency, tax jurisdiction, bank accounts), enabling it to execute financial tasks without manual form-filling.

Users interact exclusively through natural language: for example, "Create an invoice for Acme Corp for 2,500 EUR for Web Development – March 2025" triggers automatic client creation (if new), invoice generation, VAT calculation (e.g., 21%), PDF export, and storage. Similarly, queries like "What is my P&L for March?" return formatted financial summaries. All operations are stateful and persistent, forming a consistent financial memory layer for the AI.

Core Benefits and Applications

FacturaHub streamlines financial administration for independent professionals and small agencies by unifying traditionally siloed functions—billing, expense logging, tax compliance, and cash flow forecasting—into a single, conversational workflow. Practical applications include generating compliant invoices for EU clients with correct VAT treatment, reconciling quarterly VAT declarations, preparing annual income tax filings with categorized deductible expenses, and modeling near-term liquidity using automated cash flow projections. The system supports localized requirements across Europe and Latin America, including IBAN/SWIFT integration for payments and multilingual financial reporting. Its MCP architecture ensures compatibility with evolving AI assistant platforms beyond current support for Claude and Cursor.
