SSH MCP Server

# Epic 2: Real-Time Monitoring Interface ## Epic Intent Implement a web-based real-time monitoring interface that allows users to observe SSH session activity through their browser, providing live terminal output and session management capabilities. ## Story 1: Web Server Infrastructure As a developer using the SSH MCP server, I want a local web server that serves monitoring interfaces so that I can access session monitoring through my browser. ### Acceptance Criteria - **Given** the MCP server is running - **When** the web server component starts - **Then** a local HTTP server is available on a configurable port (default: 8080) - **And** the server serves static HTML/CSS/JS files for the monitoring interface - **And** the server provides WebSocket endpoints for real-time communication - **And** the server handles multiple concurrent browser connections - **And** the server starts automatically when the MCP server starts - **And** the server shuts down gracefully when the MCP server stops **Performance Requirements:** - Web server must start within 3 seconds of MCP server startup - Server must handle minimum 10 concurrent browser connections ## Story 2: Session URL Generation As a developer using Claude Code, I want to get monitoring URLs for my SSH sessions so that I can easily access the browser-based monitoring interface. ### Acceptance Criteria - **Given** an active SSH session exists with a specific name - **When** I request the monitoring URL for that session - **Then** a unique URL is generated for the session (format: http://localhost:8080/session/{session-name}) - **And** the URL includes session identification in the path - **And** the URL is immediately accessible in a browser - **And** invalid session names return appropriate error messages - **And** URLs remain valid for the lifetime of the session ## Story 3: Real-Time Terminal Output Display As a developer monitoring SSH sessions, I want to see live terminal output in my browser so that I can observe command execution in real-time. ### Acceptance Criteria - **Given** a browser is connected to a session monitoring URL - **When** commands are executed in the SSH session - **Then** terminal output is displayed in real-time in the browser - **And** output includes both stdout and stderr streams - **And** terminal colors and formatting are preserved - **And** text scrolling behaves like a standard terminal - **And** historical output is displayed when first connecting - **And** output updates have latency under 100ms - **And** special characters and escape sequences render properly **Technical Requirements:** - Use xterm.js for terminal emulation in browser - Implement WebSocket streaming for real-time updates - Support VT100/ANSI terminal escape sequences ## Story 4: Multi-Session Dashboard As a developer with multiple SSH sessions, I want a dashboard view that shows all active sessions so that I can monitor multiple connections simultaneously. ### Acceptance Criteria - **Given** multiple SSH sessions are active - **When** I access the main monitoring dashboard (http://localhost:8080/) - **Then** all active sessions are listed with their status indicators - **And** each session shows: name, host, connection status, last activity time - **And** session status uses visual indicators: 🟢 connected, 🔴 disconnected, 🟡 error - **And** clicking a session name opens the individual session monitor - **And** the dashboard updates automatically when sessions are added/removed - **And** connection health is refreshed every 5 seconds ## Story 5: Terminal Interaction Controls As a developer monitoring SSH sessions, I want basic interaction controls in the browser interface so that I can manage the monitoring experience effectively. ### Acceptance Criteria - **Given** a session monitoring interface is open - **When** I interact with the terminal display - **Then** I can scroll through historical output using mouse wheel or scrollbar - **And** I can copy text from the terminal output - **And** I can clear the terminal display locally (without affecting remote session) - **And** I can toggle auto-scroll to bottom for new output - **And** I can adjust terminal size (columns/rows) for better viewing - **And** terminal remains responsive during high-output operations ## Story 6: Session Command History Panel As a developer monitoring SSH sessions, I want to see a history of executed commands so that I can track what operations have been performed. ### Acceptance Criteria - **Given** commands have been executed in an SSH session - **When** I view the session monitoring interface - **Then** a command history panel displays the last 50 executed commands - **And** each command shows: timestamp, command text, exit code - **And** successful commands show with ✅ indicator (exit code 0) - **And** failed commands show with ❌ indicator (non-zero exit code) - **And** long commands are truncated with expandable view - **And** command history persists for the session lifetime - **And** history panel is collapsible to save screen space ## Story 7: Browser Connectivity Management As a developer using the monitoring interface, I want robust connection handling so that I can maintain reliable monitoring even with network interruptions. ### Acceptance Criteria - **Given** a browser is connected to the monitoring interface - **When** the WebSocket connection is interrupted - **Then** the interface displays connection status clearly - **And** automatic reconnection attempts are made every 5 seconds - **And** missed output is retrieved upon reconnection - **And** connection errors are displayed with user-friendly messages - **And** manual reconnect option is available - **And** connection status indicator shows: 🔗 connected, ⚠️ reconnecting, ❌ disconnected **Performance Requirements:** - Reconnection attempts must begin within 5 seconds of disconnection - Interface must remain responsive during connection issues
