A side-by-side comparison of DCP - The permission layer for AI agents and Hopper — AI Agents for Mainframe Operations - Hypercubic — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
DCP - The permission layer for AI agents
DCP (maintained by 1lystore and the DCP community)
Non-custodial permission layer that lets AI agents request vault actions while keeping keys and credentials on your device.
Key features
- Vault Permission Proxy: Exposes vault-held secrets and credentials as permissioned actions via MCP so agents can request operations without ever reading raw keys or .env files.
- Wallet Signing & Transaction Approval: Enables agents to request wallet signing (e.g., Solana) with user confirmation, keeping private keys local and non-custodial.
- Human-in-the-Loop Approvals: Desktop and mobile-driven approval flows let users approve, deny, or require manual confirmation for sensitive actions with a single tap.
- Budgets & Revocation: Configure budgets or usage limits per agent and revoke permissions dynamically to limit exposure and control ongoing agent behavior.
- Remote Pairing & Agent Deployment: Create remote invites from the Desktop app to pair VPS-hosted agents; installer can configure systemd services and automatically integrate with OpenClaw or Hermes.
- MCP Integration: Implements permission boundaries over the Model Context Protocol so multiple agent frameworks (Claude, Cursor, Hermes, OpenClaw) can interoperate with DCP.
- Agent-Safe Workflows: Prevents secrets from entering agent configuration by routing API calls and secret access through DCP, reducing credential leakage risk.
- Permission boundary for agents: grants capabilities (not raw keys) to agents via requests and approvals
- Vault and API credential access with human approval, deny, budget, and revoke controls
- Wallet signing support (example: Solana wallet address retrieval and signing flows)
- Integration with MCP so agents (Claude Desktop, Cursor, OpenClaw, Hermes, custom MCP agents) can request actions
- Desktop application for local GUI setup and invite generation
- Remote agent installer workflow that pairs VPS hosts, installs a systemd service, and auto-configures supported agents
- Automatic or manual Hermes integration (host-native config ~/.hermes/config.yaml or Docker config /opt/data/config.yaml)
- Audit trails and cryptographically verifiable artifacts via the DCP-AI protocol stack
- Ecosystem SDKs and tools (npm packages, PyPI package, WASM, CLI, Rust crates, Go reference, Docker images)
- Quickstart examples for local and remote agents to request protected data
Best for
- Secure wallet operations: Allow Claude Desktop or another agent to sign Solana transactions only after a user approves each request, without exposing private keys.
- Remote agent automation: Deploy an agent on a VPS (OpenClaw/Hermes) and pair it with DCP Desktop to grant scoped, auditable access to specific credentials for automated tasks.
- Secrets-free development: Developers test and run agent workflows locally or in CI without embedding API keys in .env files by proxying requests through DCP.
- Human-gated automation: Build automations where an agent proposes actions (banking, deployments, privileged API calls) and a human reviews and approves before execution.
- Enterprise access control: Set per-agent budgets, fine-grained permissions, and revocation policies to limit blast radius when agents access corporate APIs or data stores.
- Audit and compliance: Maintain a tamper-evident record of agent requests and human approvals for post-hoc review and regulatory compliance.
- Allowing an LLM agent to sign blockchain transactions or retrieve a blockchain wallet address without exposing private keys
- Granting a remote agent running on a VPS permission to use API credentials under human-approved budgets
- Pairing and managing remote autonomous agents (OpenClaw, Hermes) with a single-click desktop invite and systemd installer
- Enforcing per-action human approvals and budgets for agents that perform sensitive operations
- Auditing and verifying agent actions using DCP-AI cryptographic artifacts and SDKs for downstream verifiers
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.
