Let your coding agent request server work

Claude Code, Codex, Antigravity, GitHub Copilot CLI, Cursor, Devin, Kiro, Amp, OpenCode, 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 Claude Code, Codex, Antigravity, Cursor, GitHub Copilot CLI, Devin CLI, Kiro, OpenCode, Amp, 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. FrontierStack speaks the stateless MCP 2026-07-28 revision as well as the 2025 one.

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, Zellij and Rex sessions on fleet hosts. Prompts, transcripts, command lines, terminal contents and credentials stay off the phone.

Apple Intelligence for the resident assistant

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.

What changed in agent tools

Agent tools change quickly. As of November 2026, these are the changes FrontierStack handles for you.

Gemini CLI → Antigravity CLI

Personal Google accounts moved from Gemini CLI to agy on 18 June 2026. FrontierStack detects agy, runs the Gemini settings import and adds itself to the MCP config that the CLI, app and IDE share.

OpenCode 2

OpenCode 2 moved MCP servers to mcp.servers. FrontierStack writes the layout your installed version reads, moves an older entry when you upgrade, and flags a 1.x entry that 2.x would ignore.

New terminal agents

GitHub Copilot CLI, Devin CLI and Kiro CLI each have a pane and a one-click MCP setup, and FrontierStack auto-approves none of their tools.

Stateless MCP

The MCP 2026-07-28 revision dropped the session handshake and added per-request routing headers. FrontierStack accepts both that revision and 2025 clients, so older and newer agents connect to the same server.
