Quick links:

• Getting Started Guide
• Installation Options
• MCP Integration

• Multi-Package Manager Support: Automatically detects and uses npm, yarn, pnpm, or bun
• Monorepo Support: Full support for pnpm workspaces, npm workspaces, yarn workspaces, Lerna, Nx, and Rush
• Multi-Language Detection: Auto-detects commands for Node.js, Go, Rust, Java (Gradle/Maven), .NET, Python, Ruby, PHP, Flutter, and more
• Interactive TUI: Navigate through scripts, monitor processes, and view logs in real-time
• Smart Log Management:
  • Automatic error detection and prioritization
  • Log filtering and search capabilities
  • Build event and test result detection
• MCP Server Integration: Allows external tools (VSCode, Claude Code, etc.) to:
  • Access log output and errors
  • Execute commands asynchronously
  • Monitor process status
• Process Management: Start, stop, and monitor multiple processes simultaneously
• VS Code Tasks: Detects and runs VS Code tasks from .vscode/tasks.json
• Environment Variable Management (Planned):
  • Unified .env file management with multi-format support
  • TUI view for browsing and editing environment variables
  • Automatic injection for scripts and AI agents
  • Secret detection and masking for security

In a directory with a package.json file:

brum

brum [flags]

Flags:
  -d, --dir string   Working directory containing package.json (default ".")
  -p, --port int     MCP server port (default 7777)
      --no-mcp       Disable MCP server
      --settings     Show current configuration settings with sources
  -h, --help         help for brum

• Tab: Switch between views (Scripts, Processes, Logs, Errors, URLs, Settings)
• ↑/↓ or j/k: Navigate items
• Enter: Select/execute
• n: Open run command dialog (from Scripts tab)
• Esc or q: Go back
• /: Search logs
• p: Toggle high-priority logs

• Navigate: Use ↑/↓ arrows to select a process (shows status with colored indicators)
• s: Stop selected process (only works on running processes 🟢)
• r: Restart selected process (stops then starts the same script)
• Ctrl+R: Restart all running processes
• Enter: View logs for selected process

Process Status Indicators:

• 🟢 Running - Process is active (can stop/restart)
• 🔴 Stopped - Process was manually stopped
• ❌ Failed - Process exited with error
• ✅ Success - Process completed successfully
• ⏸️ Pending - Process is starting up

Automatic Cleanup:

• All running processes are automatically stopped when Brummer exits
• Use Ctrl+C or 'q' to quit with graceful cleanup
• Process count shown in header: "Running Processes (2)"

• c: Copy most recent error to clipboard
• f: View/manage filters

• ?: Show help

Brummer supports hierarchical configuration through .brum.toml files. Configuration is loaded in the following order (later values override earlier ones):

1. ~/.brum.toml (global user settings)
2. Project root and parent directories (walking up to root)
3. Current working directory .brum.toml

# Show current settings with source files
brum --settings

# Create a configuration file from current settings
brum --settings > .brum.example.toml

Create a .brum.toml file in your project or home directory:

# Package manager preference
preferred_package_manager = "pnpm"  # npm, yarn, pnpm, bun

# MCP Server settings
mcp_port = 7777
no_mcp = false

# Proxy settings
proxy_port = 19888
proxy_mode = "reverse"  # "reverse" or "full"
proxy_url = "http://localhost:3000"  # Optional: auto-proxy this URL
standard_proxy = false
no_proxy = false

The Settings tab provides:

• Package Manager Selection: Choose between npm, yarn, pnpm, or bun
• MCP Server Installation: One-click installation for development tools:
  • Claude Desktop ✓
  • Claude Code ✓
  • Cursor ✓
  • VSCode (with MCP extension) ✓
  • Cline ✓
  • Windsurf ✓
  • Roo Code (experimental)
  • Augment (experimental)
  • Cody (experimental)

Brummer Hub Mode enables MCP clients to discover and control multiple brummer instances through a single connection:

1. Configure your MCP client once:

   {
     "servers": {
       "brummer-hub": {
         "command": "brum",
         "args": ["--mcp"]
       }
     }
   }

2. Run brummer in each project:

   cd ~/projects/frontend && brum
   cd ~/projects/backend && brum

3. Use hub tools in your MCP client:

   • instances/list - See all running instances
   • instances/connect - Connect to a specific instance
   • All instance tools become available with prefixes

📚 Full Hub Mode Documentation

The MCP server runs on port 7777 by default and implements the official MCP Streamable HTTP transport protocol:

Single Endpoint: http://localhost:7777/mcp

Connection Types:

1. Standard JSON-RPC (POST with Accept: application/json)
2. Server-Sent Events (GET with Accept: text/event-stream)
3. SSE Response (POST with Accept: text/event-stream)

// SSE streaming connection
const eventSource = new EventSource('http://localhost:7777/mcp');
eventSource.onmessage = (event) => {
  const msg = JSON.parse(event.data);
  console.log('Received:', msg);
};

// Send JSON-RPC requests
fetch('http://localhost:7777/mcp', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Accept': 'application/json'
  },
  body: JSON.stringify({
    jsonrpc: '2.0',
    id: 1,
    method: 'tools/list'
  })
});

Script Management: scripts_list, scripts_run, scripts_stop, scripts_status Log Management: logs_stream, logs_search Browser Tools: browser_open, browser_screenshot, browser_navigate, repl_execute Proxy Tools: proxy_requests Telemetry: telemetry_sessions, telemetry_events
