Agentbridge MCP Server tools

This listing does not currently have a tool list to display. This does not mean the server has no tools; check its documentation for supported capabilities.

We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.

Overview

What is AgentBridge?

AgentBridge is a native Classic Mac OS application that lets AI agents (like Claude) interact with Mac OS 7–9 through structured commands and responses. It uses a shared folder for transport, works on real hardware and emulators, and requires no modifications to the Classic Mac.

How to use AgentBridge?

Install the MCP server via npm (npm install -g classic-mac-mcp) or run with npx, create a fleet.json configuration file pointing to the shared folder, then launch AgentBridge on the Classic Mac. AI agents can then send commands (e.g., ping) via files in the inbox, and AgentBridge writes responses to the outbox.

Key features of AgentBridge

  • No modifications required to the Classic Mac System.
  • List and control windows, processes, and menus.
  • Mouse and keyboard input (click, drag, type, key press).
  • Clipboard read/write operations.
  • Launch, activate, and quit applications via Apple Events.
  • Browse files and volumes on the Mac.
  • Supports multiple Classic Mac targets simultaneously.

Use cases of AgentBridge

  • Automate tasks on a vintage Mac from a modern AI assistant.
  • Test or interact with retro software without manual input.
  • Retrieve system information and clipboard contents from a Classic Mac.
  • Control emulators like BasiliskII or SheepShaver programmatically.

Frequently asked questions

1

What transport does AgentBridge use?

AgentBridge uses a shared folder as its transport. Commands are written to an `inbox` folder, and responses are read from an `outbox` folder. The folder can be on a NAS, emulator host directory, or any shared filesystem both sides can access.

2

Which Classic Mac OS versions are supported?

AgentBridge requires System 7.0 or later (for Apple Events support). It has been tested on System 7.6.1 (68k) and builds for PowerPC Mac OS 8.5–9.2.2.

3

Can I control multiple Classic Macs with one MCP server?

Yes. Each Mac gets its own subfolder (e.g., `AgentBridge-SE30`) with its own inbox/outbox/assets. The MCP server’s `fleet.json` configuration can list multiple targets, and tools accept an optional `target` parameter.

4

Do I need to modify the Classic Mac’s system?

No. AgentBridge is a regular application — launch it, quit it, done. No SSH, drivers, or system extensions are required.

5

What MCP tools are available?

The server exposes tools for system status (ping, heartbeat, system info), windows/processes, menus, mouse/keyboard, clipboard, application control, and file/volume browsing. A full list is in the MCP Tools Reference section of the README.
