A stateful serial port Model Context Protocol (MCP) server for developer tooling and AI agents. Works out of the box with Claude Code, VS Code with Copilot, and any MCP-compatible runtime. Communicates over **stdio** and uses [pyserial](https://github.com/pyserial/pyserial) for cross-platform serial on macOS, Windows, and Linux.

**Example:** Let Claude Code list available serial ports, connect to your microcontroller, reset it via DTR, and read the boot banner from your hardware.

Why this exists

If you’ve ever copy-pasted commands into `screen` or `minicom`, guessed baud rates, toggled DTR to kick a bootloader, and re-run the same test sequence 20 times — this is for you.

You have a serial device. You want an AI agent to talk to it — open a port, send commands, read responses, debug protocols. This server makes that possible.

It gives any MCP-compatible agent a full set of serial tools: listing ports, opening connections, reading, writing, line-oriented I/O, control line manipulation — plus protocol specs and device plugins, so the agent can reason about higher-level device behavior instead of just raw bytes.

The agent calls these tools, gets structured JSON back, and reasons about what to do next — without you manually typing commands into a terminal for every step.

**What agents can do with it:**

Develop and debug — connect to your device, send commands, read responses, and diagnose issues conversationally (boot banners, prompts, error codes).
