A PTY runner for MCP
Project description
pty-mcp
A lightweight PTY runner for MCP (Model Context Protocol).
pty-mcp provides terminal session tools over MCP so clients can spawn commands in a pseudo-terminal, read interactive output, send input, resize terminal windows, and manage process lifecycle safely.
Features
- Spawn shell commands in a real PTY
- Read incremental output from a ring buffer
- Wait for pattern matching (
read_until) - Send interactive input (
write) - Resize terminal (
cols/rows) - Process control (
status,wait,signal,close)
Requirements
- Python 3.10+
Installation
pip install pty-mcp
CLI Entrypoint
After installation, the package exposes:
pty-mcp
This starts the MCP server over stdio.
MCP Tools
pty_spawnpty_readpty_read_untilpty_writepty_resizepty_closepty_close_allpty_statuspty_waitpty_signalpty_list
Notes
- PTY sessions are in-memory and have idle timeout cleanup.
- The server is intended for local trusted environments.
