MCP server for persistent interactive terminal orchestration

i4z-terminal-mcp

MCP server for persistent interactive terminal sessions with a browser UI.

Features

• Persistent PTY-backed bash shells
• Concurrent terminal sessions
• Incremental output reads
• History log for input/output events
• Searchable output history
• Session env profiles and startup hooks
• Workspace profiles and groups
• Output alerts with global/session patterns
• Health summary for sessions, alerts, and persistence
• Session checkpoints and export/import bundles
• Frontend panels for profiles, workspaces, alerts, checkpoints, and snapshots
• Create/delete sessions from the web UI
• Dark/light theme toggle

Requirements

• Python 3.11+
• Linux or macOS

Install

From PyPI:

pip install i4z-terminal-mcp

From source:

pip install -e .

Build

Build a distributable wheel/sdist from source:

uv build
# or
python -m build

Run

Direct:

i4z-terminal-mcp

Or with a fixed frontend port:

I4Z_TERMINAL_WEB_PORT=9020 i4z-terminal-mcp

With OpenCode:

{
  "mcp": {
    "terminal": {
      "type": "local",
      "command": ["i4z-terminal-mcp"],
      "environment": {
        "I4Z_TERMINAL_WEB_PORT": "9020"
      },
      "enabled": true
    }
  }
}

Frontend

The server prints the web UI URL on startup:

Web UI: http://127.0.0.1:9020

Open that URL in a browser to:

• create terminal sessions
• delete terminal sessions
• send commands
• view live terminal output
• filter command/history entries
• search output history
• switch between dark and light theme

If no port is configured, the server chooses a free localhost port and prints it.
