Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@VibeWatch check my terminal for errors"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Your AI pair programmer's eyes on your terminal
VibeWatch is a CLI tool that monitors your development commands and exposes terminal output to Claude (or any MCP-compatible AI assistant) in real-time. No more copy-pasting errors - just tell Claude "check my terminal" and it sees everything.

# Install globally
npm install -g vibewatch
# Or run directly with npx
npx vibewatch npm run dev
# Your dev server runs normally, but now Claude can see it!Then ask Claude: "I'm getting an error, check my terminal" - Claude automatically sees your terminal output via MCP.
npm install -g vibewatch
vibewatch npm run devnpx vibewatch npm run devgit clone https://github.com/krjordan/vibewatch.git
cd vibewatch
npm install
npm run build
node dist/cli.js npm run devWrap any command with vibewatch:
# JavaScript/TypeScript
vibewatch npm run dev
vibewatch npx next dev
vibewatch yarn dev
vibewatch pnpm dev
# Python
vibewatch python manage.py runserver
vibewatch uvicorn main:app --reload
vibewatch pytest
# Any command
vibewatch cargo run
vibewatch go run main.govibewatch [options] <command>
Options:
-p, --port <number> API server port (default: 3333)
-b, --buffer-size <number> Log buffer size (default: 100)
-v, --verbose Include node_modules in stack traces
-r, --raw Disable noise filtering (keep all output)
-k, --keep-alive <seconds> Keep API alive after crash for MCP queries (default: 30)
-h, --help Display help
-V, --version Show version# Next.js with custom port
vibewatch --port 4444 npx next dev
# Keep API alive for 60 seconds after crash
vibewatch --keep-alive 60 npm run dev
# Disable noise filtering for debugging
vibewatch --raw npm run build
# Larger buffer for long-running processes
vibewatch --buffer-size 500 npm testAdd to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json) or Cursor MCP settings:
{
"mcpServers": {
"vibewatch": {
"command": "npx",
"args": ["-y", "-p", "vibewatch", "vibewatch-mcp"]
}
}
}Or if installed globally (npm install -g vibewatch):
