Elevating the Developer Experience with AI-Enabled Dev Docs & Tooling

Newline™ by Fifth Third is redefining the standard for developer experience with a powerful suite of tools. These AI-driven upgrades are designed to streamline workflows, reduce onboarding time and future-proof development efforts. The enhancements mark a significant leap forward in how developers interact with documentation and get started with our scalable APIs.

Model Context Protocol (MCP)

Introducing the Newline Model Context Protocol (MCP) Server—a unified interface that brings agentic capabilities to the Newline platform. This protocol enables secure, standardized access to Newline’s documentation and APIs for AI applications.

Key benefits include:

• Native integration with AI agents like Claude and GitHub Copilot
• Seamless querying of support articles and experimentation with API calls
• A growing library of prompt templates to guide implementation

The MCP server simplifies installation and unlocks powerful, context-rich interactions, allowing developers to spend less time troubleshooting and more time building.

Integration & What’s Next

Integration is available via GitHub with a straightforward setup process. Initial use cases for the MCP server will be announced soon, along with upcoming features like agentic experiences that further enhance automation and intelligence in development workflows.

Newline is live on GitHub! 

Developers and partners can now access the MCP directly from the Newline GitHub repository. As a commitment to our developer community, GitHub accelerates innovation across the Newline ecosystem. Whether you're building integrations, customizing experiences, or exploring new capabilities, everything you need is now just a clone away.

AI-Enabled Dev Docs Upgrade

The developer documentation has undergone a transformative upgrade, now powered by AI to deliver smarter, faster and more intuitive support:

• AI Conversational Search – Developers can now ask questions in natural language and receive instant, context-aware answers—including code snippets and integration guidance—directly within the documentation interface.
• SmartDocs – Documentation is always up to date, structured for AI compatibility and automatically synced across tools via the new LLM.txt protocol. This ensures consistency and reliability across the development ecosystem.
• Ask AI – A built-in dropdown menu allows users to select trusted AI tools like ChatGPT or Copilot for real-time, contextual assistance—right where they need it.

These features dramatically reduce onboarding time, lower support volume and position Newline’s platform to adapt to the evolving needs of developers.
