Grasshopper, a client-first, full-service digital bank, has partnered with Narmi, a leading digital-banking-platform provider, to roll out the next stage of their Model Context Protocol (MCP) server deployment.
The introduction of these enhanced capabilities comes as both companies aim to strengthen data integrity and encourage responsible development of AI-powered banking experiences. The MCP server now includes new read-only endpoints, supporting safe, regulated use of artificial intelligence within financial systems.
Grasshopper claims to have been the first US bank to deploy an MCP server at launch, marking a shift in how startups and small- and medium-sized businesses (SMBs) can interact with their financial data. The bank said the evolution of the platform is designed to give entrepreneurs smarter, conversational access to their information, empowering fast, informed decision making while maintaining full control over their financial data.
The upgraded MCP functionality allows users to connect their accounts to leading Large Language Models (LLMs), including Anthropic’s Claude and ChatGPT. Through OAuth integration, businesses can now grant third-party applications controlled, limited access to data without sharing sensitive login details. This ensures firms benefit from AI-driven insights while upholding stringent security standards.
Grasshopper product manager Nate Gruendemann said, “Supporting ChatGPT expands the universe of clients who can benefit from our AI connector and, together with OAuth, makes it easier and more secure for startups and small businesses to harness the power of generative AI to streamline their financial workflows.
“This evolution of the platform allows teams to explore advanced AI capabilities in a secure, consent-based framework, helping us and our partners innovate responsibly while maintaining the trust that’s core to every banking relationship.”
Narmi co-founder Chris Griffin said, “AI represents the next major channel in banking: one that meets users where they already are.
“With over 800 million people now using ChatGPT every week — an increase of nearly 300 million since March — and commanding more than 80% of the LLM market, financial institutions have an unprecedented opportunity to participate in a marketplace that’s quickly becoming foundational to how people access information and manage their financial lives. Just as mobile banking transformed accessibility fifteen years ago, MCP is positioned to level the playing field again by bringing personalized, AI-driven banking experiences directly into the tools people already use every day.”
