SSH MCP Server

# Epic 1: Core SSH Connection Management ## Epic Intent Implement persistent SSH connection management that allows Claude Code to establish, maintain, and execute commands on remote servers through named sessions with full terminal capabilities. ## Story 1: SSH Connection Establishment As a developer using Claude Code, I want to establish named SSH connections to remote servers so that I can maintain persistent sessions for distributed development workflows. ### Acceptance Criteria - **Given** valid SSH credentials and connection details - **When** I create a new SSH connection with a unique name - **Then** the system establishes a persistent SSH connection - **And** the connection is stored with the provided name identifier - **And** the connection status is tracked as 'connected' - **And** connection metadata (host, user, last activity) is maintained **Performance Requirements:** - Connection establishment must complete within 10 seconds - System must support minimum 5 concurrent SSH connections ## Story 2: SSH Command Execution As a developer using Claude Code, I want to execute bash commands on remote servers through named SSH sessions so that I can run development operations remotely. ### Acceptance Criteria - **Given** an active SSH session exists with a specific name - **When** I execute a bash command through that session - **Then** the command is sent to the remote server via SSH - **And** the command output (stdout/stderr) is captured completely - **And** the command exit code is returned - **And** the working directory context is maintained between commands - **And** environment variables are preserved across command executions - **And** interactive commands are supported with proper TTY allocation **Performance Requirements:** - Command execution must begin within 2 seconds of request - Output streaming must have latency under 100ms ## Story 3: Connection Health Monitoring As a developer using Claude Code, I want automatic monitoring of SSH connection health so that I can be notified of connection issues and have reliable session management. ### Acceptance Criteria - **Given** one or more SSH connections are established - **When** the system monitors connection health - **Then** each connection status is updated every 30 seconds - **And** failed connections are marked with 'error' status - **And** connection failures include error details and timestamps - **And** automatic reconnection attempts are made for failed connections - **And** maximum retry attempts are configurable (default: 3) - **And** exponential backoff is used between reconnection attempts ## Story 4: Session State Persistence As a developer using Claude Code, I want SSH sessions to maintain their terminal state so that I can continue work across multiple command executions. ### Acceptance Criteria - **Given** an SSH session is executing commands - **When** commands modify the terminal environment (cd, export, etc.) - **Then** subsequent commands inherit the modified environment - **And** working directory changes persist across commands - **And** environment variable modifications persist across commands - **And** command history is maintained per session - **And** background processes remain active between command executions ## Story 5: Multiple Session Management As a developer using Claude Code, I want to manage multiple named SSH sessions simultaneously so that I can work with multiple remote servers concurrently. ### Acceptance Criteria - **Given** multiple SSH sessions are required - **When** I create sessions with different names - **Then** each session maintains independent connection state - **And** each session has isolated working directories - **And** each session has isolated environment variables - **And** session names are unique and validated - **And** I can list all active sessions with their status - **And** I can disconnect specific sessions by name - **And** session cleanup occurs when connections are closed **Performance Requirements:** - System must handle minimum 5 concurrent sessions - Session isolation must prevent cross-session interference
