mcp-terminal-emulator 0.2.0

MCP server for interactive terminal sessions with cross-platform PTY support

🖥️ MCP Terminal Server

Interactive terminal sessions via Model Context Protocol (MCP)

MCP Terminal Server provides cross-platform PTY (pseudo-terminal) support for Windows, Linux, and macOS, exposing terminal sessions through both REST API and MCP protocol. Perfect for AI assistants, remote terminal access, and terminal automation.

✨ Features

• 🌍 Cross-platform: Works on Windows (cmd.exe/PowerShell), Linux, and macOS
• 🔄 Real PTY: Supports interactive commands (vim, nano, htop, etc.)
• 👁️ Visual Snapshots: Captures what a human would see on the terminal screen
• 🔤 UTF-8 Support: Handles special characters and emojis correctly
• 🚀 MCP Protocol: Auto-exposes all endpoints as MCP tools via fastapi-mcp
• 📡 REST API: Full HTTP/REST API with FastAPI
• 🎯 Multiple Sessions: Manage multiple terminal sessions simultaneously

📖 Usage

REST API

Create a Terminal

curl -X POST http://localhost:8777/terminals \
  -H "Content-Type: application/json" \
  -d '{"rows": 24, "cols": 80}'

Response:

{
  "success": true,
  "terminal_id": "550e8400-e29b-41d4-a716-446655440000",
  "message": "Terminal created successfully"
}

Send Commands

curl -X POST http://localhost:8777/terminals/{terminal_id}/input \
  -H "Content-Type: application/json" \
  -d '{"data": "echo Hello World\n"}'

Get Visual Snapshot

curl http://localhost:8777/terminals/{terminal_id}/snapshot

Response:

{
  "terminal_id": "550e8400-e29b-41d4-a716-446655440000",
  "display": "C:\\Users\\...\nHello World\nC:\\Users\\...> ",
  "lines": ["C:\\Users\\...", "Hello World", "C:\\Users\\...> "],
  "cursor": {"row": 2, "col": 15},
  "size": {"rows": 24, "cols": 80},
  "is_alive": true,
  "created_at": "2024-01-01T00:00:00"
}

List Terminals

curl http://localhost:8777/terminals

Resize Terminal

curl -X PUT http://localhost:8777/terminals/{terminal_id}/resize \
  -H "Content-Type: application/json" \
  -d '{"rows": 30, "cols": 100}'

Close Terminal

curl -X DELETE http://localhost:8777/terminals/{terminal_id}

MCP Tools

When using with MCP clients (like Claude Desktop), the following tools are automatically available:

• create_terminal_terminals__post - Create new terminal
• list_terminals_terminals__get - List active terminals
• get_terminal_snapshot_terminals__terminal_id__snapshot_get - Get visual snapshot
• send_terminal_input_terminals__terminal_id__input_post - Send commands
• resize_terminal_terminals__terminal_id__resize_put - Resize terminal
• close_terminal_terminals__terminal_id__delete - Close terminal

Python API

from mcp_terminal import TerminalManager

# Create manager
manager = TerminalManager()

# Create terminal
terminal_id = await manager.create(rows=24, cols=80)

# Send input
await manager.send_input(terminal_id, "echo Hello\n")

# Get snapshot
snapshot = await manager.get_snapshot(terminal_id)
print(snapshot["display"])

# Close terminal
await manager.close(terminal_id)
