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.

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

Popcraft
Popcraft
MCP server that lets Claude, ChatGPT, Cursor and other agents generate video, images, music and sound effects through Popcraft.
Key features
- One-URL MCP Integration: Add a single endpoint as a custom connector in Claude, ChatGPT, Cursor, Claude Code, Codex or other MCP clients with OAuth sign-in and no API key.
- Multimodal Generation: Generate video, images, music and sound effects directly from prompts inside your agent conversation.
- Credit Cost Preview: Agents preview credit costs and get approval before generating, avoiding surprise spend.
- Skills Served Live: Loads production skills such as ugc-ad and thumbnail-pro from the server so the agent follows a tested workflow.
- UGC Product Ad Workflow: Turns a product photo into a vertical creator-style ad with storyboard, realism pass and a Seedance 2.0 clip with native speech.
- Multi-Model Access: Reach Seedance 2.0, Nano Banana, Seedream and GPT Image models from one account.
Best for
- Marketing Video Ads: Have an agent produce a 15-second vertical UGC ad from a product photo.
- YouTube Thumbnails: Generate concept variants and micro-edits for video thumbnails.
- Brand Stills and Voiceover: Create image sets and audio for a campaign in one conversation.
- Cinematic Teasers: Produce short cinematic clips from a written brief.
- Agent-Driven Content Pipelines: Let coding or chat agents add media generation to larger workflows.
- A/B Creative Testing: Ask for alternate hooks or aspect ratios and download variants.
