Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Control Classic Mac OS (System 7-9) from AI agents via shared folder protocol.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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).

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.

The transport is just a folder. How that folder is shared between the AI and the Mac is up to you:
No SSH. No special drivers. No modifications to your Mac's system. AgentBridge is a regular application — launch it, quit it, done.
The MCP server exposes these tools to AI agents. If the fleet has only one target, the target parameter is optional on all tools.

You should see RESULT pong and STATUS ok.
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.
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).
npm install -g classic-mac-mcp
Or run directly with npx (no install needed):
npx -y classic-mac-mcp --config /path/to/fleet.json
git clone https://github.com/SeanFDZ/agentbridge.git
cd agentbridge npm install npm run build
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" } ] }
