IBM AS/400 iSeries

Connects to IBM AS/400 and iSeries mainframe systems through RTE protocols (TN5250, TN3270, VT420) with YAML-configurable terminal interaction flows for automated login sequences, menu navigation, and screen output retrieval.

A Spring Boot-based MCP server that enables AI assistants to interact with IBM AS/400 and iSeries mainframe systems through RTE (Remote Terminal Emulator) protocols including TN5250, TN3270, and VT420. Built by Abstracta using the jmeter-bzm-rte library, it provides a configurable YAML-based approach for defining connection parameters and automated terminal interaction flows, allowing users to execute mainframe login sequences and retrieve screen output as text. Particularly valuable for modernizing legacy system interactions, enabling AI assistants to perform mainframe operations like user authentication and menu navigation without requiring direct terminal access or specialized mainframe knowledge.
