Claude Merkezi

A toolkit for running Claude Code across multiple machines and projects — without ever pasting a server password into the chat.

Türkçe README · Node.js ≥ 18.17 · Windows & macOS · MIT

Claude Merkezi ("Claude Hub" in Turkish) has three parts:

The user interface and messages are in Turkish.

Highlights

• MCP server written from scratch — JSON-RPC 2.0 over stdio, no SDK. 10 tools:

  Tool	Purpose
  sunucular	List the servers linked to the current project (no secrets)
  listele, indir	List a remote folder, download a file
  yukle	Upload to a test server. Only changed files are sent; onizleme shows the plan first
  ssh_komut	Run a command on a test server
  canli_yukle, canli_ssh_komut	Same for production — requires user approval on every call
  isler, is_ekle, is_guncelle	Read and update the hub's task board

• Encrypted vault — AES-256-GCM. The key is protected by Windows DPAPI or the macOS Keychain. Password-protected backups use scrypt key derivation.

• SSH host key pinning — the server's identity is stored on first connect; a changed key is rejected.

• Live session tracking — 12 Claude Code hooks (SessionStart, PreToolUse, PostToolUse, Notification, Stop, …) report to the hub. Prompts and commands are truncated and password-like values are masked before they leave the machine; file contents and tool outputs are never sent.

• Zero-config networking — the hub is discovered over UDP broadcast; machines pair with a 6-digit code; the dashboard is password protected.

• One-step install / uninstall — registers the MCP server, adds hooks to ~/.claude/settings.json (with a backup), sets up auto-start and a desktop shortcut. Re-running is safe.

• Tests — unit, integration and vault tests with the built-in node:test runner.

• Two runtime dependencies only: ssh2 and basic-ftp.

Getting started

git clone https://github.com/CeyDrew/claude-merkezi.git
cd claude-merkezi
node kur.js          # interactive install (or Kur.bat / Kur.command)

1. On the first machine, answer E (yes) to "make this machine the hub", then open http://127.0.0.1:7380 and set a dashboard password.

2. On other machines, choose Makineler > Yeni bilgisayar ekle in the dashboard to get a 6-digit code, copy the folder over and run the installer. It finds the hub on the network automatically.

3. Start Claude with the Claude Başlatıcı shortcut (or node baslatici.js).

Now you can simply tell Claude "deploy this project to the test server" and it will use the vault tools.

Uninstall hooks, MCP registration and auto-start with node kur.js --kaldir (your data is kept).

Security model

• The vault lives in ~/.claude-merkezi/kasa.json, outside the app folder.

• Claude runs as the same OS user, so this is not a hard security boundary. The goal is to keep credentials out of the conversation, logs and Claude's normal workflow. Use least-privilege server accounts.

• .git, node_modules, .claude and .env* files are never uploaded.

• The hub uses plain HTTP on the local network. Do not use it on untrusted networks.
