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
- Automated mainframe operations and incident remediation
- Autonomous JCL generation and job submission
- Debugging and root-cause analysis of failed jobs
- Querying and inspecting VSAM datasets and other data stores
- Accelerating COBOL and legacy application maintenance and modernization
- Creating agent-driven operator assistants for z/OS workflows
Noodle Seed
Noodle Seed
Platform for making software agent-ready, turning existing product workflows into secure MCP apps and embedded conversational assistants.
Key features
- MCP App Deployment: Build and deploy headless versions of an existing SaaS product as MCP Apps that any MCP client can call.
- Embedded Assistant Runtime: Drop a conversational assistant into a product or public site, running on the same runtime that governs agent actions.
- Identity and Permission Carrying: Customer and account context travels with every request, and agents operate under the roles, scopes, and credential rules the product already enforces.
- Single Control Plane: Run, inspect, and update every agent experience from one place, with policies and audit logs on higher tiers.
- Managed Secrets and Rollback: Credentials are managed for you, and deployment history lets teams roll back a release.
- Solution Starters: Ready-made starting points for travel and booking, customer support, and HR or employee requests, including a working travel concierge example.
- Pooled Usage Billing: MCP calls are pooled monthly across every app on a billing account instead of being priced per seat.
- Local-First Development: Develop and prove a workflow locally without an account before deploying it.
Best for
- Agent-Ready SaaS: Expose an existing product's core workflows so ChatGPT, Claude, or Copilot users can complete them without leaving the assistant.
- Travel Concierge: Let customers search and book flights or stays conversationally, built from the travel and booking starter.
- Customer Support Deflection: Handle account-specific support requests through an embedded assistant that respects the caller's real permissions.
- HR and Employee Requests: Route internal requests such as time off or policy questions through a governed conversational interface.
- Conversational Commerce: Open a public marketing site to AI-driven discovery, lead capture, and purchase flows before signup.
- Enterprise Agent Governance: Centralise policies, audit logs, and private connectivity for every agent experience an organisation runs.
