Turret Controller MCP Server

Description

This project is an MCP (Model Context Protocol) server that controls a turret using serial communication. It exposes tools to:

• Fire the turret
• Set the turret's position (pan and tilt)
• Get the current number of bullets

Usage

This server exposes tools that can be accessed via an MCP client.

Tools

• fire: Fires the turret.
• set_turret_position: Sets the turret's position. Requires x and y coordinates (0-180).
• get_bullets: Gets the current number of bullets.
• echo: Repeat what you say.

Installation

1. Make sure you have Rust installed. If not, install it from https://www.rust-lang.org/.
2. Clone the repository.
3. Navigate to the project directory.
4. Run cargo build -r to build the project.
5. MCP Agent Plugin node require settings.json like this to command or URL to connect MCP servers

{
  "mcpServers": {
    "turret-mcp-server": {
      "command": "/path/to/turret_mcp_server/target/release/turret_mcp_server",
      "alwaysAllow": [
        "set_turret_position",
        "get_bullets",
        "fire"
      ]
    }
  }
}

6. Connect the turret to USB

How to use

In chat context you can simple write: turn the turret left, then right and shoot

Serial Port Configuration

The server uses the /dev/ttyUSB0 serial port by default. You may need to modify the turret_mcp_server.rs file to use the correct serial port for your system.

Dependencies

The project uses the following dependencies:

• anyhow
• rmcp
• serialport
• serde_json
• tracing_subscriber

These dependencies are managed by Cargo, the Rust package manager.

Docker

You can also build and run this project using Docker.

Building the Docker Image

To build the Docker image, run the following command in the project directory:

docker build -t turret-mcp-server .

Running the Docker Container

To run the Docker container, you need to pass the serial port device from the host to the container. You can do this using the --device flag.

docker run -it -p 8080:8080 --device=/dev/ttyUSB0 turret-mcp-server

The SSE MCP configuration (settings.json) for Docker looks like this:

{
  "mcpServers": {
    "turret-mcp-server": {
      "url": "http://127.0.0.1:8080/sse"
    }
  }
}

Note: Make sure to replace /dev/ttyUSB0 with the correct serial port for your system.
