MCP 服务器

HT-MCP

ht-mcp is useful for enabling Agents to use terminals (e.g. bash, zsh, fish) in the same way a human does. It solves the challenge of agents stalling when they encounter interactive terminal commands.

README

ht-mcp

A high-performance Rust implementation of a Model Context Protocol (MCP) server for headless terminal ht.

Features

🚀 Pure Rust: Single binary MCP server, no external dependencies
🔗 Direct Integration: Embed excellent ht headless terminal library for optimal performance
🖥️ Multi-Session: Concurrent terminal session management
🌐 Web Interface: Optional live terminal preview

MCP Tools

Tool	Description	Parameters
`ht_create_session`	Create new terminal session	`command?`, `enableWebServer?`
`ht_send_keys`	Send keystrokes to session	`sessionId`, `keys[]`
`ht_take_snapshot`	Capture terminal state	`sessionId`
`ht_execute_command`	Execute command and get output	`sessionId`, `command`
`ht_list_sessions`	List all active sessions	None
`ht_close_session`	Close terminal session	`sessionId`

Note: Parameters use camelCase (e.g., sessionId, enableWebServer) for MCP compatibility.

Configuration

Add to your MCP client configuration:

{
  "mcpServers": {
    "ht-mcp": {
      "command": "ht-mcp",
      "args": ["--debug"]
    }
  }
}

For custom installation paths:

{
  "mcpServers": {
    "ht-mcp": {
      "command": "/path/to/ht-mcp",
      "args": []
    }
  }
}

Usage Example

# Start the MCP server
ht-mcp

# With debug logging
ht-mcp --debug

Once configured in your MCP client:

Create session: ht_create_session → Returns session ID
Run commands: ht_execute_command with session ID and command
Interactive input: ht_send_keys for multi-step interactions
Check state: ht_take_snapshot to see current terminal
Clean up: ht_close_session when finished

Response Format

This server returns human-readable text responses (not JSON), designed for natural language interaction:

# Create session response
HT session created successfully!

Session ID: abc123-def456-789...

🌐 Web server enabled! View live terminal at: http://127.0.0.1:3618

# Terminal snapshot response
Terminal Snapshot (Session: abc123...)
