terminalSafety --Repository

Execute shell commands in persistent, stateful VT100 terminal sessions. WHEN: User needs to "run a command", "execute shell", "build project", "run tests", "deploy", system administration. WHEN NOT: Simple file operations (use fs_* tools), reading known files (use fs_read_file).

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

ActionDescriptionRequired Parameters
EXECExecute command (default)command
READGet current buffer snapshotNone
LISTShow all active terminalsNone
KILLGracefully shutdown terminalNone

Key Parameters

ParameterTypeDefaultDescription
actionstring"EXEC"Action to perform
terminalnumber0Terminal instance (0, 1, 2...)
commandstringnullCommand to execute (EXEC only)
await_completion_msnumber300000Max wait time (5 min default)
clearbooleantrueClear buffer before command
tailnumber2000Max 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)
