### Description (declared)

# 🔌 serial-mcp

MCP server for serial port communication. Provides tools to open, read, write, and manage serial ports through the Model Context Protocol.

*🤖 Written by and for AI.*

## ✨ Features

- 📋 List available serial ports on the system
- ⚙️ Open ports with configurable baud rate, parity, stop bits, and flow control
- 📖 Read data by byte count, terminator character, or duration
- ✍️ Write string or hex data
- 💥 Send BREAK signals
- 📊 Monitor port status and control line states

## 📦 Prerequisites

- Python 3.10+
- [uv](https://docs.astral.sh/uv/getting-started/installation/) package manager

## 🛠️ Tools

| Tool | Description |
|------|-------------|
| `list_ports` | List available system serial ports |
| `open_port` | Open a serial port with configuration (baud rate, parity, stop bits, etc.) |
| `close_port` | Close an open port |
| `write_data` | Write string or hex data to a port |
| `read_bytes` | Read N bytes with timeout |
| `read_until` | Read until a terminator character |

| `get_port_status` | Get port status and control line states |
| `list_open_ports` | List all currently managed ports |

## 🧪 Testing with Virtual Ports

Use `socat` to create virtual serial port pairs for testing:

```bash
# Create virtual port pair
socat -d -d pty,raw,echo=0,link=/tmp/tt…
