🛠 zrald4 - Solution Implementation MCP Server

The ultimate solution implementation MCP server that creates and executes comprehensive solutions based on insights from zrald1, zrald2, and zrald3. Features sequential task breakdown, testing, and validation to ensure correct implementation.

🎯 Overview

zrald4 is the final and most advanced server in the zrald ecosystem, designed to:

• Create comprehensive solutions based on user requests and insights from all previous servers
• Break down solutions into exactly 10 sequential tasks
• Execute tasks one by one with testing and validation at each step
• Ensure correct implementation before proceeding to the next task
• Provide real-time progress tracking and execution status

🔗 Dependencies

REQUIRED: All three previous zrald servers must be running before using zrald4.

# Start all dependencies in order
npx -y zrald1  # File analysis and graph processing
npx -y zrald2  # Function logic analysis
npx -y zrald3  # Sequential thinking and reasoning

# Then start zrald4
npx -y zrald4  # Solution implementation

📦 Installation

Global Installation

npm install -g zrald4

Direct Usage

npx -y zrald4

🛠 MCP Tools

3. get_solution_status

Get current status and progress of solution execution.

Parameters:

• solution_id: ID of solution (optional, uses current if not provided)

4. validate_all_dependencies

Validate that zrald1, zrald2, and zrald3 are all available and accessible.

5. pause_solution

• tasks://current - All tasks in the current solution
• progress://current - Current execution progress and status
• insights://current - Solution insights and recommendations

🔄 Sequential Task Execution

zrald4 breaks every solution into exactly 10 sequential tasks:

1. Requirements Analysis & Validation - Analyze and validate feasibility
2. Architecture Design & Planning - Design solution architecture
3. Dependency Analysis & Setup - Identify and prepare dependencies
4. Core Implementation - Phase 1 - Implement core functionality
5. Integration & Interface Development - Develop interfaces and integrate
6. Error Handling & Validation - Implement error handling
7. Testing & Quality Assurance - Create and execute test suite
8. Performance Optimization - Optimize performance
9. Security Review & Hardening - Conduct security review
10. Documentation & Deployment - Create documentation and deploy

Task Execution Process

For each task:

1. Execute implementation steps sequentially
2. Apply code changes if any
3. Run tests to verify functionality
4. Validate completion against acceptance criteria
5. Test task completion before proceeding to next task
6. Rollback on failure if enabled
