JACKSONVILLE, Fla. — Nymbus has launched Nymbus MCP Server, describing it as one of the first secure Model Context Protocol servers designed specifically for core banking, according to the company.
The server, built for the Nymbus Banking Platform, is intended to give banks and credit unions a standardized and controlled way to connect artificial intelligence-powered tools directly to core systems through a single interface, Nymbus said.
The company said the MCP Server is designed primarily for front-office banking operations and currently includes 19 tools that allow AI assistants to perform common tasks such as customer lookups, account management, money movement and debit card controls. The platform translates those capabilities into a format that AI agents can use to securely execute approved core functions through large language models, while financial institutions retain control over permissions and approvals.
Nymbus said institutions can determine which tools are enabled, which employees have access and where additional review or authorization is required, allowing them to embed AI into workflows while maintaining oversight.
Multiple Actions
According to Nymbus, the system allows employees to complete multiple actions through a single interface. For example, a member service representative could verify a customer, review account details and initiate a debit card freeze without switching between systems. The company said similar AI-assisted workflows could accelerate processes such as fraud investigations, case management and operational follow-up.
The MCP Server is built on Nymbus’ open integration architecture and analytics platform, which the company said eliminates the need for custom integrations for each AI use case by providing a single connection layer to core systems, according to the company.
Nymbus said the platform incorporates features aimed at meeting regulatory and operational requirements, including token-based authentication, role-based access controls, encryption, audit logging and masking of personally identifiable information in logs.
Because the server is based on an open MCP standard, it also provides a foundation for more advanced AI-driven banking interactions, including systems that can coordinate tasks across multiple platforms within institution-defined controls, the company said.
