Mainframe Mcp Server
Expose IBM z/OS jobs, datasets, USS, and diagnostics to your coding agent through Zowe SDK-backed MCP tools.
Overview
Mainframe MCP Server is an Operate-phase MCP server that lets agents manage and diagnose IBM z/OS jobs, datasets, USS, and ops tasks via the Zowe SDK and z/OSMF.
What is this MCP server?
- @notharshhaa/mainframe-mcp-server v2.5.0 npm stdio MCP over Zowe SDK
- z/OSMF auth via ZOSMF_HOST plus ZOSMF_USER/ZOSMF_PASSWORD or ZOSMF_TOKEN
- Tools for jobs, datasets, USS paths, and operational diagnostics
- Configurable ZOSMF_PORT (default 443) and optional ZOSMF_BASE_PATH gateway prefix
- Package version 2.5.0
- Connects via Zowe SDK to z/OSMF (default HTTPS port 443)
- Supports token or basic authentication to z/OSMF
What problem does it solve?
Maintaining z/OS as a solo specialist means brittle one-off scripts and portal hopping every time you need job or dataset context.
Who is it for?
Independent mainframe admins and devs with z/OSMF access who want agent-assisted job, dataset, and USS diagnostics.
Skip if: Cloud-native-only builders, teams without IBM Z contracts, or environments where agents cannot hold mainframe credentials.
What do I get? / Deliverables
With z/OSMF credentials configured, your agent can query and operate on mainframe resources through standardized MCP tools at v2.5.0.
- MCP tools for z/OS jobs, datasets, USS, and operational diagnostics
- Stdio MCP server configured against your z/OSMF endpoint (v2.5.0)
- Reduced ad-hoc scripting for routine mainframe inquiries

How it compares
IBM z/OS specialist connector via Zowe, not a general Kubernetes or Talos Linux MCP.
Common Questions / FAQ
Who is Mainframe MCP Server for?
It is for developers and operators on IBM z/OS who use z/OSMF and want Claude Code or Cursor to interact with jobs, datasets, and USS through MCP.
When should I use Mainframe MCP Server?
Use it in Operate when triaging batch jobs, inspecting datasets, or running diagnostics on a live z/OS system you already manage.
How do I add Mainframe MCP Server to my agent?
Install @notharshhaa/mainframe-mcp-server v2.5.0 as stdio MCP, set required ZOSMF_HOST and authentication (ZOSMF_USER/ZOSMF_PASSWORD or ZOSMF_TOKEN), and optional port or base path vars.
