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...) bash-3.2$ ls -la total 16 drwxr-xr-x 4 user staff 128 Jun 13 10:30 . -rw-r--r-- 1 user staff 45 Jun 13 10:30 file.txt bash-3.2$

Requirements

Rust: 1.75+ (install via rustup)
Supported OS: Linux, macOS, Windows (experimental)

Development

# Clone with submodules git clone --recursive https://github.com/memextech/ht-mcp.git cd ht-mcp # Build cargo build # Run cargo run # Test cargo test

Troubleshooting

Installation Issues:

Ensure Rust 1.75+ is installed
Check internet connection for git submodules
Verify ~/.cargo/bin is in PATH

Runtime Issues:

Use ht-mcp --debug for verbose logging
Check MCP client configuration syntax
Verify binary path: which ht-mcp

Performance

Compared to the original TypeScript implementation:

40x faster startup (~50ms vs ~2s)
70% less memory (~15MB vs ~50MB)
Single binary (4.7MB vs ~200MB Node.js)
Zero subprocess overhead
