terminal - Shell Command Execution

Core Concept

mcp__plugin_kg_kodegen__terminal executes shell commands in persistent VT100 terminal sessions. Terminals maintain environment variables, working directory, and shell state across commands. Use different terminal numbers for parallel work.

Actions

Action	Description	Required Parameters
EXEC	Execute command (default)	command
READ	Get current buffer snapshot	None
LIST	Show all active terminals	None
KILL	Gracefully shutdown terminal	None

Key Parameters

Parameter	Type	Default	Description
action	string	"EXEC"	Action to perform
terminal	number	0	Terminal instance (0, 1, 2...)
command	string	null	Command to execute (EXEC only)
await_completion_ms	number	300000	Max wait time (5 min default)
clear	boolean	true	Clear buffer before command
tail	number	2000	Max output lines to return

Usage Examples

Execute Command (default action)

{ "command": "ls -la" }

Execute in Specific Terminal

{ "terminal": 1, "command": "cargo build --release" }

Background Execution (fire-and-forget)

{
  "command": "npm run build",
  "await_completion_ms": 0
}

Execute with Timeout

{
  "command": "cargo test",
  "await_completion_ms": 60000
}

Read Current Buffer

{ "action": "READ", "terminal": 0 }

List All Terminals

{ "action": "LIST" }

Kill Terminal

{ "action": "KILL", "terminal": 0 }

Response Format

{
  "terminal": 0,
  "exit_code": 0,
  "cwd": "/project/path",
  "duration_ms": 1234,
  "completed": true
}

Parallel Work Pattern

Use different terminal numbers for concurrent tasks:

// Terminal 0: Build
{ "terminal": 0, "command": "cargo build" }

// Terminal 1: Tests (parallel)
{ "terminal": 1, "command": "cargo test" }

// Terminal 2: Watch logs
{ "terminal": 2, "command": "tail -f app.log" }

Background Execution

For long-running commands:

1. Fire-and-forget: await_completion_ms: 0
2. Check progress: { "action": "READ", "terminal": N }
3. Wait with timeout: If timeout occurs, command continues in background

Important Notes

• Persistent sessions: Environment and working directory preserved
• VT100 emulation: Actual rendered terminal output, not raw bytes
• Automatic cleanup: Terminals cleaned up on connection close
• State preservation: cd commands persist across calls

Remember

• Terminals are numbered 0, 1, 2... - use different numbers for parallel work
• Default action is EXEC - just provide command
• Use await_completion_ms: 0 for background tasks
• Use action: "READ" to check on background commands
• Working directory persists - cd works across commands
• For simple file operations, prefer fs_* tools (faster, safer)
