MCP server for operating TinySA through serial port

Sorry, I'm currently experimenting and cannot guarantee that it will work properly.

Overview

This project is an MCP server designed to operate a TinySA device via a serial port. It leverages Python libraries such as pyserial, httpx, numpy, Pillow, and FastMCP to provide a tool-based interface for connecting to the device, executing commands, and retrieving device version information.

Features

• Send commands and retrieve responses from the device.
• Retrieve firmware and hardware version information.
• Exposes MCP tools for integration with other systems.
• Supports image capture from the device screen, and optional file saving with timestamps.

MCP Tools

The following MCP tools are available:

• get_version: Retrieve version information from the TinySA device.
• execute_command: Send a command to the TinySA device and get the response.
• connect: Connect to the TinySA device on a specified port.
• disconnect: Disconnect the TinySA device.
• get_device_info: Retrieve detailed information about the connected device.
• capture_image: Capture the TinySA screen image and optionally save it to a file with a timestamp.

Usage Example

Invoke the MCP tools using an MCP client. For example, to get the device version:

mcp call get_version --args '{"port": "COM4"}'

Troubleshooting

• Connection Issues: Ensure the specified serial port is correct and that your user has appropriate permissions.
• Command Failures: Check the MCP server logs (if available) for error messages.
• Image Capture: Verify that the device returns sufficient data (307200 bytes) during image capture.
• Refer to the Model Context Protocol documentation for more information on MCP integration.

Materials

Refer to the material directory for additional documentation, it will be good to add the file "USB interface.txt" as a AI knowledge.
