tinystruct-mcp is a modular Java MCP server module based on tinystruct framework, providing built-in tools for file system and GitHub operations via the Model Context Protocol (MCP) as an example. It's designed for easy integration, automation, and extensibility in modern DevOps and AI-driven workflows.

import org.tinystruct.ApplicationContext;
import org.tinystruct.application.Context;
import org.tinystruct.system.ApplicationManager;
import org.tinystruct.system.Settings;
import org.tinystruct.system.HttpServer;

public class Main {
    public static void main(String[] args) {
        Context ctx = new ApplicationContext();
        ctx.setAttribute("--server-port", "8080");
        ApplicationManager.init();
        ApplicationManager.install(new org.tinystruct.mcp.GitHub());
        ApplicationManager.install(new org.tinystruct.mcp.FileSystem());
        ApplicationManager.install(new HttpServer());
        ApplicationManager.call("start", ctx);
    }
}

If you have the bin/dispatcher script (from the Tinystruct distribution), you can start the server directly from the command line:

To start the server with the built-in GitHub and FileSystem modules:

bin/dispatcher start --import org.tinystruct.system.HttpServer --import org.tinystruct.mcp.GitHub --import org.tinystruct.mcp.FileSystem --server-port 777 

• You can add or remove imports to customize which modules and tools are loaded.

Provides Git and GitHub API operations:

• Clone repositories: github/clone
• Pull changes: github/pull
• Push changes: github/push
• Check status: github/status
• Get issues: github/issues
• Get pull requests: github/prs
• Get workflows: github/actions

Provides file system operations:

• Get file info: filesystem/info
• Check existence: filesystem/exists
• Get file size: filesystem/size
• List directory: filesystem/list
• Read file: filesystem/read
• Write file: filesystem/write
• Copy file: filesystem/copy
• Move file: filesystem/move
• Delete file: filesystem/delete
• Create directory: filesystem/mkdir

Configure the server using a properties file or by setting values in the Settings object:

# Example: mcp.properties
mcp.auth.token=your-secret-token

MCP stands for Model Context Protocol.
