MCP - Software Management 🚀

A local Model Context Protocol (MCP) server that empowers AI coding agents to manage software on a computer in a safe, automated, and non-interactive way.

This project focuses on system automation: it enables AI agents to execute common software management workflows through explicit MCP tools, from installing applications to checking updates and recommending software for specific tasks.

🌟 Overview

Modern AI coding agents excel at understanding requirements and automating tasks, but they often lack standardized, non-interactive access to system software management workflows.

This project bridges that gap by exposing software management capabilities as explicit MCP tools, allowing AI agents to manage system software safely and predictably without relying on terminal prompts or interactive installers.

🏗️ Architecture

The project follows a clean layered architecture inspired by best practices from modern MCP servers:

main.py (MCP Tool Endpoints)
    ↓ Async/Sync Bridge (asyncio.to_thread)
services/ (Business Logic)
    ↓
utils/ (Low-level Utilities)
    ↓
models/ (Data Validation)

Architecture Principles

• Separation of Concerns: Each layer has a single responsibility
• Error Handling: Structured error codes for programmatic handling
• Non-Interactive: All operations run asynchronously, suitable for AI agents
• Type Safety: Pydantic models for input/output validation
• Immutability: Frozen dataclasses for reliable state management

🧾 Error Codes Reference

The MCP server returns structured error codes for programmatic error handling:

🧰 Troubleshooting

1) Installation fails with “Software not found”

Symptom:

{
  "ok": false,
  "error": {
    "code": "software_not_found",
    "message": "Software 'xyz' not found in database"
  }
}

Fix:

• Check software name spelling (case-insensitive)
• Use list_installed_software to see available options
• Verify supported software in the table above

2) Update fails with “Already up to date”

Symptom:

{
  "ok": false,
  "error": {
    "code": "up_to_date",
    "message": "Software 'python' is already up to date (v3.11.0)"
  }
}

Fix:

• This is expected behavior when software is current
• No action needed

3) Recommendation returns empty for unknown task

Symptom:

{
  "ok": false,
  "error": {
    "code": "software_not_found",
    "hint": "Available tasks: web development, data science, ..."
  }
}

Fix:

• Use supported task names from the list
• Task names are case-insensitive
• View all tasks using the recommendations documentation

4) Registry operations fail

Symptom:

{
  "ok": false,
  "error": {
    "code": "registry_error",
    "message": "Error saving registry"
  }
}

Fix:

• Verify file permissions in project directory
• Check available disk space
• Ensure software_registry.json is not corrupted
• Delete registry file to reset (will recreate on next operation)

📊 Software Registry

The system maintains a persistent software_registry.json file that tracks:

• Installed software and versions
• Installation dates
• Auto-update preferences

Example Registry:

{
  "installed_software": {
    "python": {
      "version": "3.11.0",
      "installed_date": "2026-02-18T10:30:00.123456",
      "auto_update": false
    },
    "git": {
      "version": "2.43.0",
      "installed_date": "2026-02-18T10:35:00.654321",
      "auto_update": true
    }
  }
}

🔁 Example Workflow

1. Discover recommendations for a task:

   Call: get_recommendations("web development")
   Result: Receive list of recommended software
   

2. Install recommended software:

   Call: install_software("python")
   Call: install_software("nodejs")
   

3. List installed software:

   Call: list_installed_software()
   Result: View all installed programs and versions
   

4. Check for updates:

   Call: check_updates()
   Result: See available updates
   

5. Update individual software:

   Call: update_software("python")
   Result: Update to latest version
   

6. Enable auto-updates:

   Call: set_auto_update("python", true)
   Result: Enable automatic updates
   

🚧 Future Improvements

The following features would further enhance the server:

• Batch Operations: Install/update multiple software at once
• Dependency Resolution: Automatic installation of software dependencies
• Repository Integration: Support for custom software repositories
• Scheduled Updates: Cron-like scheduling for automatic updates
• Health Checks: Verify installation integrity and functionality
• Rollback: Revert to previous software versions
• Configuration Profiles: Save and restore system configurations
