Amp, DeepSeek Harness Alpha, Codex, Claude Code, Cursor, Grok-based coordinators and other agents can investigate a problem or request a change. They do not receive your SSH keys, server passwords or cloud credentials.
The agent coordinates the job; FrontierStack decides what may run. It authenticates the caller, returns only the relevant tools, supplies credentials locally, applies your rules, waits for approval when needed, and checks the result.
The workflow
1. An agent requests work
A coding tool, manager agent, CI system or incident workflow describes a bounded job. It receives fleet context and task-relevant tools, not a dump of every credential or command.
2. FrontierStack authorizes it
App Lock, caller scope, read-only defaults, destructive-action rules and local approval decide what may run. Prompt text, an agent identity claim or a chat approval cannot widen that authority.
3. The result is verified
FrontierStack executes locally or on the selected Linux, Windows or Mac host, checks the observed postcondition, records the audit event and returns a result the coordinator can use.
Choose the connection
Interactive MCP
Best for Amp, Codex, Claude Code, Cursor, Gemini CLI, the agents inside Xcode 26.3+ and desktop assistants. The agent discovers a small task-specific catalog and calls guarded FrontierStack tools from the editor or terminal.
Durable delegation
Use opt-in A2A or MCP Tasks when work must survive a chat turn, report progress, pause for input or approval, support cancellation and finish with a receipt.
Events, CLI and automation
Authenticated events may start read-only triage. The FrontierStack CLI gives scripts and CI a stable interface, and it works with the app closed. Read-only checks run straight away, and anything else starts the app in the background. An optional background service keeps MCP answering and keeps your monitors and alerts running while the app is closed. Neither route carries infrastructure credentials or silently grants change permission.
Supervise the work from anywhere
Agent Operations on the Mac shows worker-host health, runtimes, jobs and durable terminal sessions. The iPhone and iPad companion shows bounded Agent Activity from the paired Mac and can list tmux, GNU screen and Zellij sessions on fleet hosts. Prompts, transcripts, command lines, terminal contents and credentials stay off the phone.
The agents you connect over MCP and the model FrontierStack reasons with are separate choices. On macOS 27 the resident AI Administrator can run on Apple Intelligence: the on-device Apple foundation model for private, offline, key-free work. Your coding agents keep using whatever model they prefer.
Give an agent team a network administrator
A ready-made role for Grok Bot and other MCP clients: diagnose DNS, certificates, routers and firewalls on your real network, without the bot ever receiving a credential.
Monitor DeepSeek's plugin-based developer-preview agent harness, with local and remote CLI detection plus an optional guarded FrontierStack MCP plugin from FrontierStack.
Monitor the open-source orchestrator that runs a team of AI agents as a company. FrontierStack can also join it as the company's system engineer and network administrator from FrontierStack.
