Hopper — AI Agents for Mainframe Operations - Hypercubic
Hypercubic
Agentic TN3270 emulator that lets AI agents operate z/OS: navigate ISPF, write column-strict JCL, debug jobs, and query VSAM.
Key features
- Agentic TN3270 Emulation: Provides a real TN3270 terminal interface that AI agents can interact with to perform terminal-based workflows and operations inside z/OS.
- Model Context Protocol Integration: Connects AI agents to mainframe systems via Model Context Protocol, enabling contextualized, stateful interactions and natural-language commands.
- ISPF Navigation and Interaction: Lets agents navigate ISPF menus, edit dataset members, and perform common ISPF tasks programmatically to automate operator workflows.
- Column-Strict JCL Generation: Generates, validates, and edits column-strict JCL compliant with mainframe formatting rules, reducing errors and manual rework.
- Job Debugging and JES Integration: Diagnoses failed jobs by examining JES output, suggests fixes or corrective JCL edits, and supports resubmission workflows.
- VSAM and Dataset Querying: Enables agents to query, inspect, and modify VSAM files and other datasets directly from the terminal context for data investigation and remediation.
- Autonomous Workflows and Natural-Language Ops: Orchestrates multi-step autonomous tasks initiated via natural language, combining terminal actions, queries, and code edits.
- Knowledge Capture and Documentation: Records operational procedures and extracts institutional knowledge from mainframe artifacts (COBOL, JCL) for documentation and modernization.
- Agentic TN3270 terminal emulation
- Natural-language agent workflows for ISPF/JCL/JES/CICS
- Column‑strict JCL generation and job debugging
- Dataset and VSAM querying
Best for
- Automated Job Recovery: Detect failed batch jobs, analyze JES logs, generate corrected JCL, and resubmit jobs with minimal human intervention to reduce downtime.
- JCL Authoring and Validation: Produce column-strict JCL for new or migrated batch processes, validate formatting and dependencies, and enforce site-specific JCL standards.
- Dataset Investigation and Remediation: Locate datasets via ISPF, query VSAM contents, identify data issues, and apply scripted fixes or migration steps.
- COBOL Documentation and Knowledge Capture: Extract program structure and business logic from COBOL sources, generate human-readable documentation, and preserve institutional knowledge.
- Operator Onboarding and Assistance: Provide interactive, agent-guided terminal sessions that teach new operators how to navigate ISPF and perform common operational tasks.
- Legacy Modernization Workflows: Automate discovery, refactoring, and migration tasks for legacy workloads by combining terminal interactions with scripted modernization procedures.
- Automating routine mainframe operations (job submission, debugging)
- Generating and validating column‑strict JCL
- Exploring and querying VSAM/datasets via agents
- Accelerating COBOL/mainframe modernization tasks
- Providing hands‑on evaluation environments for mainframe dev teams
- Automated mainframe operations and incident remediation
KodHau MCP — The Governance Layer for your AI Agents
KodHau
KodHau MCP gives your AI agents the tribal knowledge of your team—PR history, design decisions, and review comments your engineers never documented.
Key features
- Tribal Knowledge Ingestion: Aggregates undocumented team knowledge such as PR history, design notes, and review comments to provide contextual signals for agents.
- PR and Code History Contextualization: Links pull request metadata and discussions to agent prompts so suggestions and actions reflect past decisions and rationale.
- Design Decision Capture: Stores and surfaces design rationale and trade-offs to ensure agents recommend solutions consistent with previous architectural choices.
- Review Comment Retrieval: Exposes reviewer feedback and comments to agents to prevent repeated mistakes and replicate reviewer expertise in automated workflows.
- Agent Governance Controls: Provides a governance layer that aligns agent outputs with team norms, enabling traceability and oversight of automated decisions.
- Onboarding and Knowledge Transfer: Uses captured institutional knowledge to accelerate new team member ramp-up and reduce reliance on tacit expertise.
- Ingests and indexes PR history as structured knowledge for agents
- Captures and stores design decisions and rationale
