Mainframe Mcp Server
Bridges Claude to IBM mainframe environments through the Zowe SDK, letting you work with z/OS jobs, datasets, Unix System Services files, and run operational diagnostics without leaving your conversation. You get programmatic access to submit and monitor JCL jobs, read and write mainframe datasets, navigate USS directories, and pull system metrics. Reach for this when you need to automate mainframe operations, debug production issues, or build workflows that span modern APIs and legacy z/OS systems. Requires Zowe CLI configuration with your mainframe credentials and connection profiles.
