VibeTTY

AI-assisted SSH/Telnet/Serial management in VSCode

VSCode extension + MCP server for managing remote infrastructure with AI assistance.

⚠️ VIBECODED PROTOTYPE ⚠️

The code quality of this project is abysmal and security is mostly left to chance.
I would strongly advise against using VibeTTY in production environments.

🚀 Quick Start

1. Install

From VSIX:

# Download .vsix from releases or build from source
# Install: Extensions → `...` → Install from VSIX

Build from Source:

git clone https://github.com/torbbang/vibetty.git
cd vibetty
npm install && npm run compile
vsce package

2. Add Connections

1. Open VibeTTY sidebar
2. Click + → Choose SSH/Telnet/Serial
3. Fill in details → Connect

3. Setup MCP

MCP enables AI assistants (Claude Code, Cline, etc.) to interact with VibeTTY.

Automatic: Command Palette → VibeTTY: Configure MCP Client

Manual: Add to MCP client config:

{
  "mcpServers": {
    "vibetty": {
      "command": "node",
      "args": ["/path/to/vscode-vibetty/out/mcp/cli.js"]
    }
  }
}

For the best user experience I recommend auto-approving the following tools:

• list_connections
• list_active_sessions
• show_terminal
• read_output
• auto_paginate
• set_device_type

✨ Features

Connections:

• SSH/Telnet/Serial with ProxyJump, port forwarding, keep-alive
• Multiple concurrent sessions per host
• Folder organization with drag-and-drop
• Persistent terminals (don't close on disconnect)

AI Integration (MCP):

• 8 MCP tools for Claude Code, Cline, Gemini, etc.
• List/connect/command/read output with approval gates
• Auto-pagination through --More-- prompts
• Device type detection (Cisco IOS/IOS-XE, Juniper Junos, FortiOS)

Security:

• 50+ secret filtering patterns (passwords, SNMP, BGP keys, etc.)
• Strict Mode: manual approval for all AI commands
• Edit-before-submit approval dialogs
• Localhost-only MCP server with token auth

UX:

• SecureCRT-compatible keyword highlighting
• Auto-focus on password prompts
• Session logging with daily rotation
• Connection notes for device documentation

🔒 Security

Protection Layers:

1. Secret Filtering - 50+ patterns for Cisco/Juniper/FortiOS (passwords, SNMP, BGP keys, etc.)
2. Strict Mode - Manual approval for all AI commands/output (toggle in status bar)
3. Network Isolation - Localhost-only MCP server with token auth (port 47632)
4. File Permissions - Session logs and auth token stored with 0600 (owner-only)

Limitations:

• Pattern-based filtering may miss uncommon secret formats
• Session logs contain unfiltered output (user responsibility to secure)
• Connection notes stored in plaintext VSCode settings
