As enterprises look to deploy AI safely at scale, Fifth Third (NASDAQ:FITB) today announced continued investment in Model Context Protocol (MCP) capabilities through Newline™ by Fifth Third, its embedded finance business. The next phase of Newline's MCP 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 MCP 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 MCP in Dec. 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 MCP foundation by guiding AI models to correctly use tools, apply predefined workflows, review and generate code and follow established development templates. Together, MCP and Skills create a unified framework that enables more capable AI agents, scalable automation and greater value across Newline's technology stack.

"Newline builds with a scale that supports what's next and continues to innovate the next generation of commerce," said Tom Bianco general manager of Newline. "We're backed by the power, stability and financial strength of bank with a nearly 170-year history, but we move at the pace of a Silicon Valley fintech."

Newline is part of Fifth Third's Commercial Payments business, which processed more than $18 trillion in payments volume in 2025 and is the sixth-largest Commercial Payments provider by revenue. The Bank continues to expand its capabilities through strategic acquisitions—including Big Data Healthcare, Rize Money, Inc., and DTS Connex—to advance innovation in healthcare payments, embedded finance and cash logistics.
