Included Base Components

Included at no charge with any Connect/MP Suite license.

Connect/Web New

The engine of the AI-enabled mainframe.

The high-performance z/OS web server powering Connect/MP’s AI and mainframe modernization features. One lightweight binary drives it all: batch and interactive agentic AI, MCP REST APIs, agentic 3270 and browser access, and more. No JVM, no middleware, no external dependencies.

Connect/MP Workspace

One browser-based surface for chat, JES, Files, and 3270 sessions. Web chat included at no charge — z/OS agentic workflows unlocked by Connect/AI.

Connect/JES

Operationalize JES for modern workflows.

Native to z/OS, Connect/JES automatically identifies JES output that meets defined criteria and triggers Connect/MP processing to deliver mission-critical data to FTP servers, email recipients, enterprise applications, and AI inference pipelines. REST API access from any platform is provided through Connect/Web.

Connect/Files New

z/OSMF-compatible dataset and USS file access, direct and fast.

Connect/Files provides read, write, and delete access to sequential datasets, PDS members, and USS files — fully SAF-gated and drop-in compatible with your existing z/OSMF tooling. Powered by Connect/Web.

Connect/USS New

Simplify and streamline z/OS batch Unix System Services (USS) execution integration.

Connect/USS replaces file system–based processing with direct, stream-based data exchange, removing filesystem overhead and improving throughput and execution efficiency.

Connect/Hybrid

Streamline hybrid IT operations by integrating mainframe systems with cloud and distributed platforms — no middleware required.

Connect/Hybrid automates secure, high-speed data and application integration across your enterprise, reducing complexity and accelerating time to value.

Connect/MP › AI Platform

The Mainframe as an AI Platform — Inference and Agentic 3270.

Every major enterprise AI initiative eventually runs into the same problem: the data that matters most is on the mainframe, and getting it to the model cleanly, securely, and at scale is harder than it looks. Connect/AI changes that equation — bringing inference to the data rather than the other way around, running AI workloads directly within the z/OS environment under existing governance, without changing how batch jobs are structured or scheduled.

The same principle extends to 3270 applications. Billions of transactions still flow through these interfaces every day, yet that data has been largely inaccessible to modern AI systems — locked behind a terminal designed for human operators. Connect/3270 opens that interface to AI inference, making mainframe screen data structured, queryable, and actionable in real time — while simultaneously giving human users browser-based 3270 access without changing the underlying application.

Together, Connect/AI and Connect/3270 make the mainframe a first-class participant in the enterprise AI stack — not as a data source to be extracted from, but as a governed, high-performance inference and integration platform in its own right.

The mainframe wasn’t left out of the AI era. It was ready first.

PKZIP Replacement

The Suite That Pays Its Own Way.

Replace PKZIP for z/OS with Connect/ZIP and cut your compression licensing cost by 50% — real dollars, not list-price games. At enterprise MSU levels, those savings can fund Connect/AI, Connect/3270, or both. Modernize the mainframe with budget you already have.
