Common questions

Is Agentbridge safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 7 months ago, and the latest version (1.0.2) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

AgentBridge

Let AI talk to your Classic Mac.

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 works on real hardware and emulators — no modifications to your Mac required.

Drop AgentBridge into a shared folder, launch it on your Mac, and an AI agent can list windows, open apps, type text, read the clipboard, browse files, and more — all through a simple text-based protocol.

How It Works

┌──────────────────────┐

│ Claude / AI Agent │ │ │ │ │ MCP Protocol │ │ │ │ │ MCP Server (Node) │ │ │ │ │ Shared Folder I/O │ └────────┬─────────────┘ │ reads/writes text files │ ┌────┴──────────────────────────┐ │ Shared Volume (NAS / AFP / │ │ SMB / emulator extfs) │ │ │ │ AgentBridge-MyMac/ │ │ ├── inbox/ ← commands in │ │ ├── outbox/ ← responses out │ │ ├── assets/ ← file staging │ │ └── heartbeat │ └────┬──────────────────────────┘ │ ┌────────┴─────────────────────────┐ │ Classic Mac OS 7 / 8 / 9 │ │ │ │ AgentBridge.app │ │ - Polls inbox for commands │ │ - Executes via Mac Toolbox │ │ - Writes responses to outbox │ │ - Heartbeat every 2 seconds │ └──────────────────────────────────┘

The transport is just a folder. How that folder is shared between the AI and the Mac is up to you:

NAS/file server (AFP or SMB) — multiple Macs and your modern computer all mount the same share
Emulator shared folder — BasiliskII and SheepShaver both support host directory sharing
Any other shared filesystem — if both sides can read and write files, it works

No SSH. No special drivers. No modifications to your Mac's system. AgentBridge is a regular application — launch it, quit it, done.

Compatibility

Environment	Architecture	OS Versions	Status
68k Macs	68k	System 7.0–8.1	✅ Tested on System 7.6.1
PowerPC Macs	PowerPC	Mac OS 8.5–9.2.2	Builds, untested
BasiliskII	68k	System 7.0–8.1	✅ Tested on System 7.6.1
SheepShaver	PowerPC	Mac OS 8.5–9.2.2	Builds, untested

AgentBridge requires System 7.0 or later (for Apple Events support).

Quick Start

Pre-built Binaries

Download from the Releases page:

`AgentBridge-68k.bin` — MacBinary for 68k Macs (System 7–8.1)
`AgentBridge-68k.dsk` — HFS disk image for 68k Macs (System 7–8.1)
`AgentBridge-ppc.bin` — MacBinary for PowerPC Macs (OS 8.5–9.2.2)
`AgentBridge-ppc.dsk` — HFS disk image for PowerPC Macs (OS 8.5–9.2.2)

Setup

Create a shared folder accessible to both your Mac and your modern computer. This can be a NAS share, an emulator's host directory, or any shared filesystem.

Create the directory structure inside the shared folder:

   AgentBridge/

└── AgentBridge-YourMacName/ ├── inbox/ ├── outbox/ └── assets/

Copy AgentBridge into the folder alongside inbox/outbox/assets.

Launch AgentBridge on the Classic Mac. It will automatically find its folder and start polling for commands.

Send a test command from your modern computer:

   printf "BRIDGE 1.0.1\rSEQ 00001\rCMD ping\rTS 20260308T170000\r---\r" > /path/to/shared/AgentBridge-YourMacName/inbox/C00001.msg

Read the response:

   cat /path/to/shared/AgentBridge-YourMacName/outbox/R00001.msg | tr '\r' '\n'

You should see RESULT pong and STATUS ok.

Multiple Macs

Each Mac gets its own subfolder with its own copy of AgentBridge:

NAS Share/

└── AgentBridge/ ├── AgentBridge-SE30/ ← Mac SE/30 running System 7 │ ├── AgentBridge (app) │ ├── inbox/ │ ├── outbox/ │ └── assets/ ├── AgentBridge-G4/ ← Power Mac G4 running OS 9 │ ├── AgentBridge (app) │ ├── inbox/ │ ├── outbox/ │ └── assets/ └── AgentBridge-BasiliskII/ ← Emulator ├── AgentBridge (app) ├── inbox/ ├── outbox/ └── assets/

AgentBridge uses its own launch location as its working directory — no configuration needed.

MCP Server

The MCP server exposes AgentBridge commands as tools for AI agents like Claude. It's a Node.js TypeScript server that communicates via stdio (standard MCP transport).

Install via npm

npm install -g classic-mac-mcp

Or run directly with npx (no install needed):

npx -y classic-mac-mcp --config /path/to/fleet.json

Install from source

git clone https://github.com/SeanFDZ/agentbridge.git

cd agentbridge npm install npm run build

Configuration

Create a fleet.json file to point at your shared folders:

"fleet": [ { "id": "my-classic-mac", "alias": "Classic Mac", "arch": "68k", "os_version": "7.6.1", "shared_folder": "/Volumes/NASShare/AgentBridge/AgentBridge-MyMac" } ] }
