Rearchitecting financial services customer experience for the MCP generation

AI is transforming how financial institutions serve customers, support employees, manage financial services, and operate across increasingly complex technology environments. But one question stands above the rest: Who controls the future of your customer and employee experiences, your institution or your technology vendors?

At Avaya, we believe the answer should be you. That is why we are embracing the open future of AI, building the Avaya Infinity® platform to support Model Context Protocol (MCP).

It is the right move for financial institutions that need to innovate without abandoning trusted systems, sensitive financial data, established workflows, or the security and governance requirements that protect customers and the institution.

For too long, bringing AI into financial services customer experience has meant choosing between two difficult options:

• Lock in to a single provider's closed ecosystem, limiting flexibility as AI models, customer expectations, regulatory requirements, security priorities, and business strategies evolve
• Create costly, one-off integrations across core financial systems, CRM, payments, lending, fraud, card services, wealth platforms, knowledge systems, identity services, and other applications

This false choice slows innovation and places additional pressure on already complex financial technology environments. It can also fragment the customer experience, especially when information is distributed across legacy and modern platforms.

Enter MCP, an open, vendor-agnostic standard designed to help AI models interact with tools, data, and operational logic securely and at scale.

Think of MCP as a universal connection layer for AI. Instead of building a different connection between every model and every financial system, organizations can create a standardized way for approved AI capabilities to access the context and tools they need.

As the AI ecosystem evolves, this approach can give financial institutions greater freedom to innovate while maintaining control over the systems, data, workflows, and customer relationships that make their institution unique.

MCP enables AI systems to operate with dynamic awareness of customer, employee, session, transaction, and financial context.

For Avaya Infinity, this means AI models can deliver experiences informed by relevant information across complex financial environments. A customer interaction could draw upon approved account, CRM, payment, fraud, lending, knowledge, and interaction data while respecting the permissions governing each source.

That level of contextual intelligence can be especially valuable for financial institutions managing thousands of employees, products, systems, workflows, integrations, transactions, and customer journeys across multiple channels and lines of business.

A typical financial institution may have dozens or hundreds of tools and data sources, including core financial platforms, CRM, payment systems, lending applications, fraud detection, card platforms, wealth management systems, identity services, knowledge bases, document repositories, analytics environments, and workforce applications. At the same time, multiple AI models, copilots, applications, and agents may need controlled access to those systems.

Before MCP, connecting each system to each AI model could require its own point-to-point integration. As the number of systems and AI capabilities grows, so does the development effort, maintenance burden, complexity, and technical debt. MCP changes that paradigm by introducing a standardized intermediary layer. Instead of solving an increasingly complex N x M integration problem, financial institutions can move toward a more scalable N + M model. Each financial tool can expose approved capabilities through an MCP server, while AI models and applications connect through MCP clients. Once components can communicate through MCP, financial institutions gain a more flexible foundation for connecting AI with existing and future systems. That can dramatically reduce redundant integration work while protecting investments already made in the technologies and workflows that support customers today.

This matters because financial services customer journeys rarely live in one application. A single interaction may touch communications, CRM, core financial systems, payments, lending, fraud, cards, identity, knowledge, authentication, and analytics. Avaya Infinity with MCP can help connect those technologies, insights, channels, and workflows so financial institutions can modernize the experience without requiring the entire technology environment to be replaced first.

With MCP, Avaya Infinity users can unlock deeper business value by giving AI access to more relevant context and approved enterprise capabilities.

For financial institutions, that can mean faster customer service, more informed fraud interactions, more efficient employee workflows, more natural conversations, greater workforce productivity, and better continuity throughout the financial journey.

MCP creates the foundation for generative and agentic AI that is not simply intelligent, but situationally aware of the customer, employee, account, transaction, financial relationship, and permissions surrounding an interaction.
