Artificial intelligence is rapidly transforming wealth management. Advisors now rely on AI copilots—such as ChatGPT, Gemini, and Claude—to streamline reporting, research, and client servicing.
Yet despite their impressive capabilities, these models share one critical limitation: they do not have native, standardized access to structured, reliable, and secure financial data unless connected through an appropriate secure architecture.
Flanks, the European WealthTech firm specializing in multi-bank aggregation, is addressing this gap with the introduction of its Model Context Protocol (MCP) Server, a secure architecture that connects any AI assistant to real, verified wealth data.
The missing link: high-quality data for AI
In wealth management, data quality and security are non-negotiable. Even the most advanced AI model cannot deliver accurate insights without a solid, trusted data foundation.
This is precisely where Flanks steps in.
Wealth managers can experiment with AI copilots, but these tools typically operate in isolation, disconnected from client portfolios, transactions, or custodial data.
Flanks’ MCP Server acts as the control, governance, and data-quality layer, securely connecting, standardizing, and validating multi-bank data before exposing it to AI.
“The promise of AI in wealth management depends entirely on data quality,” explains Álvaro Morales, Chairman of Flanks. “The MCP ensures that AI copilots can work with accurate and verified data, safely and efficiently.”
This helps AI provide more consistent, explainable, and compliant insights grounded in real data, not assumptions.
A secure standard for AI–data interaction
Originally defined by Anthropic and now adopted as an emerging multi-vendor standard, the Model Context Protocol describes how AI can safely connect to external systems. Flanks has implemented this framework with a strong emphasis on security, traceability, and data governance.
The architecture consists of three layers:
- Host – the AI assistant (ChatGPT, Gemini, Claude, etc.)
- Client – the secure communication bridge
- Server – where verified financial data becomes accessible in a controlled environment
This layered approach allows wealth managers to integrate AI directly into existing workflows while maintaining full control over permissions, provenance, and compliance.
Applications for wealth managers
The Flanks MCP Server offers a range of ready-to-use tools designed for financial operations:
- Portfolios: consolidated overview and filtering across institutions.
- Holdings: analysis by asset, ISIN, or valuation date.
- Transactions: traceable historical activity.
- Connect: onboarding of new banks or custodians.
- Credentials: monitoring of connection status and data integrity.
Through these interfaces, wealth managers can request specific information using natural language—for example:
“List all client portfolios above €100,000 with more than 10% exposure to energy.”
The assistant retrieves and analyzes the data instantly, providing a reliable, auditable response sourced directly from connected institutions.
Security, accuracy, and governance by design
Beyond operational efficiency, the MCP is fundamentally a data-governance framework.
Key advantages include:
- Coverage: access to over 200 banking connectors across European institutions, through a combination of direct, PSD2, and other supported connection methods
- Accuracy: ISIN-level validation and harmonized valuation formats
- Speed: technical onboarding can be completed in seconds, with full data availability depending on each institution’s authentication and data refresh process.
- Security: fully aligned with European data protection standards
This combination ensures that AI systems can operate safely on high-quality, normalized, and enriched financial data—something AI models cannot guarantee on their own.
An important step for the industry
As AI moves from experimentation to integration, the firms that succeed will be those that combine intelligence with data integrity.
Flanks’ MCP Server provides exactly this foundation:
- secure connectivity
- high-quality aggregated data
- enhanced analytical capabilities for AI copilots
For wealth managers, the outcome is clear: AI becomes a more reliable partner by grounding answers in validated financial data grounded in real, compliant, and validated financial information.
“Clean data transforms AI from an idea into a practical resource,” concludes Morales. “With MCP, we are laying the foundation for truly data-driven advisory services.”
