Fifth Third announced continued investment in Model Context Protocol capabilities through Newline by Fifth Third, its embedded finance business. The next phase of Newline?s Model Context Protocol Server introduces Skills. This new layer standardizes how AI models use tools, workflows and helps developers automate faster and with more intelligent system performance, while maintaining stronger governance.

The Newline Model Context Protocol Server securely connects AI models to external resources, data and services, standardizing how AI agents access Newline APIs and interact with information beyond their training data. Since introducing Model Context Protocol in December 2025, Fifth Third has expanded its capabilities through enhancements designed to simplify integrations, improve developer productivity and ensure AI systems can reliably interact with enterprise financial services. Skills builds on the Model Context Protocol foundation by guiding AI models to correctly use tools, apply predefined workflows, review and generate code and follow established development templates.

Together, Model Context Protocol and Skills create a unified framework that enables more capable AI agents, scalable automation and greater value across Newline?s technology stack. Newline by Fifth Third provides BIN sponsorship and a modern API-driven platform that enables enterprise clients to launch payment, card, and deposit products directly with the Bank. Its technology helps clients embed financial capabilities seamlessly into their products, backed by Fifth Third?s standards for performance, scalability, and risk management.
