What is Mobile MCP Validator?

Mobile MCP Validator is an AI assistant supervision tool specifically designed for mobile development. It integrates into the Cursor IDE through the Model Context Protocol (MCP) and verifies code quality in real-time when the AI writes code, ensuring that the AI assistant follows professional development specifications rather than writing code randomly.

How to use Mobile MCP Validator?

After installation, Mobile MCP Validator will automatically work in the background. When the AI assistant attempts to write or modify mobile app code, it checks whether the code complies with preset rules, such as file size limits, architectural separation, and UI state integrity. If a problem is found, it will prevent the AI from continuing until the problem is fixed.

Applicable Scenarios

Suitable for all scenarios where AI assistants are used for mobile development, especially: 1. Flutter, React Native, iOS, or Android development using the Cursor IDE 2. Teams that want to maintain code quality and consistency 3. Preventing AI assistants from disrupting the existing architecture 4. Ensuring that UI/UX meets professional standards

Main Features

Enforce Task Planning

Requires the AI to create a detailed task plan before starting to code, preventing random code modifications.

Code Quality Verification

Automatically checks code quality, including file size, function complexity, architectural separation, etc.

Breaking Change Detection

Detects whether the AI has accidentally modified code that should not be changed, preventing the disruption of existing functions.

UI/UX Best Practices

Comes with a complete UI/UX design guide to ensure that the interfaces created by the AI are professional and consistent.

Multi-Platform Support

Supports Flutter, React Native, native iOS, and native Android development.

Blocking Validation

Prevents the AI from continuing to code when a serious problem is found until the problem is fixed.

Advantages

Prevents the AI from randomly modifying code and maintains the stability of the codebase.

Enforces professional development specifications and improves code quality.

Reduces code review time as the code generated by the AI is more in line with team standards.

Supports multiple mobile development frameworks, with a wide range of applications.

Comes with a UI/UX guide to ensure the consistency of interface design.

Limitations

Requires configuration and integration into the development environment.

May require adjustment of validation rules for non-conventional projects.

May increase the initial planning time for AI coding.

How to Use

Clone the Repository

Clone the Mobile MCP Validator project to your local machine.

Configure Cursor IDE

Edit Cursor's MCP configuration file and add the Mobile MCP Validator server.

Add Server Configuration

Add the startup command for Mobile MCP Validator to the configuration file.

Restart Cursor

Restart the Cursor IDE for the configuration to take effect.

Project Configuration (Optional)

Create a configuration file in the project to customize validation rules.

Usage Examples

Case 1: Add a New Feature Page

The AI needs to add a new user profile page.

Case 2: Fix an Existing Feature

The AI needs to modify an existing settings page.

Case 3: Refactor Complex Code

The AI needs to refactor an overly complex component.

🚀 Mobile MCP Validator

Stop AI "Vibe Coding" — Enforce Disciplined Mobile Development

This tool is an MCP (Model Context Protocol) server for Cursor IDE, acting as a guardian for your mobile codebase, preventing AI from writing scattered and unplanned code.

🚀 Quick Start

1. Clone the Repository

git clone https://github.com/emran1993/mobile-mcp-validator.git
cd mobile-mcp-validator
dart pub get

2. Add to Cursor

Add to your ~/.cursor/mcp.json:

{
  "mcpServers": {
    "mobile-mcp-validator": {
      "command": "dart",
      "args": ["run", "/path/to/mobile-mcp-validator/bin/mobile_mcp_validator.dart"]
    }
  }
}

3. Restart Cursor

That's it! The MCP is now protecting your codebase.

✨ Features

🎯 Task Planning (No More Random Changes)

The AI must create a plan before coding:

User: "Add a settings screen"

AI calls: create_task_plan()

→ Task 1: Analyze existing patterns
→ Task 2: Create settings controller  
→ Task 3: Build settings screen with all UI states
→ Task 4: Run validation
→ Task 5: Verify code quality

🚫 Blocking Errors (Forces Fixes)

When the AI makes a mistake, it gets blocked:

{
  "success": false,
  "isBlocking": true,
  "message": "BLOCKING: File exceeds 300 lines (found: 425)",
  "fixSuggestion": "Split into smaller modules..."
}

The AI cannot proceed until it fixes the issue.

🔍 Breaking Change Detection

Before modifying existing code:

AI takes a "snapshot" of the current state
After changes, compares to detect unintended modifications
Alerts if classes, methods, or APIs were accidentally removed

🎨 UI/UX Best Practices

Design Principles — Visual hierarchy, spacing, consistency
Color Systems — Palettes, dark mode, contrast

🎯 Built this MCP to solve the "vibe coding" problem I kept seeing with AI assistants

Why I Built This

"After years of building mobile apps, I've learned that the difference between amateur and professional code isn't just functionality — it's discipline. Planning before coding. Consistent patterns. Clean architecture. Beautiful, accessible UIs.

When AI assistants started helping with code, I noticed they often lacked this discipline. They'd jump into coding without a plan, create massive files, ignore patterns, and produce inconsistent UIs.

Mobile MCP Validator is my solution. It brings the discipline of a senior developer to AI-assisted coding. It's the guardian I wish I had when I started — and now it's available for everyone."
