Structured Workflow MCP Server

An MCP server that enforces disciplined programming practices by requiring AI assistants to audit their work and produce verified outputs at each phase of development.

Why I Built This

TLDR: I found that prompting with these two words: inventory and audit, helped make the AI think systematically and follow structured phases in development, but got tired of repeating them across every platform and prompt - so I built this MCP server to enforce this discipline automatically.

The Details: Like many of you, over the last year of learning to use AI in development, I got frustrated with AI not thinking through problems the way I do.

When I approach a problem, I ask: How are these components connected? How do they relate to other systems? What side effects will this change produce? What steps ensure success? What already exists in my codebase?

AI skips this analysis. It jumps into code changes without understanding the system it's building into. It creates new classes and folder structures when they already exist. It adds code without understanding component relationships or potential side effects. The result was usually duplicated classes, functions, unused helpers, and other code that didn't fit the system I was working on.

Planning modes helped, but didn't always force the AI to break down the problem properly, especially in larger existing codebases. Eventually I discovered two key words: inventory and audit. Forcing AI to INVENTORY and AUDIT before acting was the key to getting the model to be thorough and disciplined in understanding the system it was working on. But I had to keep repeating these instructions across multiple prompts and different AI platforms.

I looked for existing MCP tools but didn't find anything quite like what I needed. The Sequential Thinking MCP server was inspiring (and I still use this a lot), but I needed something that went further - forcing AI to follow structured phases and produce verifiable output before proceeding.

So I built this for myself. I need this kind of disciplined workflow. If others find it useful, great. If not, no worries - I'll keep using it because it solves my problem.

I'm sharing this in case others have similar frustrations. Contributions, improvements, and discussion are welcome.

Features

Enforced Workflow Phases - AI must complete specific phases in order (audit, analysis, planning, implementation, testing, etc.)

Mandatory Output Artifacts - Each phase requires structured documentation or verified outputs before proceeding

Multiple Workflow Types:

• Refactor workflows for code improvement
• Feature development with integrated testing
• Test-focused workflows for coverage improvement
• Test-driven development (TDD) cycles
• Custom workflows for specialized needs

Output Verification - The server validates that outputs contain meaningful content and proper structure

Session State Management - Tracks progress and prevents skipping phases

Global Installation (Optional)

You can install globally (local) first:

npm install -g structured-workflow-mcp

Then use in your AI assistant config:

{
  "mcp": {
    "servers": {
      "structured-workflow": {
        "command": "structured-workflow-mcp",
        "args": [],
        "env": {}
      }
    }
  }
}

Auto-Install via Smithery

For Claude Desktop users (Smithery has other options like direct add to Cursor):

npx -y @smithery/cli install structured-workflow-mcp --client claude

Manual Installation

For developers:

git clone https://github.com/kingdomseed/structured-workflow-mcp
cd structured-workflow-mcp
npm install && npm run build

Usage

Once configured in your AI assistant, start with these workflow tools:

• mcp__structured-workflow__build_custom_workflow - Create custom workflows
• mcp__structured-workflow__refactor_workflow - Structured refactoring
• mcp__structured-workflow__create_feature_workflow - Feature development
• mcp__structured-workflow__test_workflow - Test coverage workflows

Example Output Artifacts

The server enforces that AI produces structured outputs like these:

AUDIT_INVENTORY Phase Output:

{
  "filesAnalyzed": ["lib/auth/user_service.dart", "lib/auth/auth_middleware.dart"],
  "dependencies": {
    "providers": ["userProvider", "authStateProvider"],
    "models": ["User", "AuthToken"]
  },
  "issues": [
    "Single Responsibility Principle violation - handles too many concerns",
    "File approaching 366 lines - recommended to keep widgets smaller"
  ],
  "changesList": [
    {
      "action": "CREATE",
      "file": "lib/auth/components/auth_form.dart",
      "description": "Extract authentication form logic",
      "justification": "Component focused on form validation only"
    }
  ]
}

COMPARE_ANALYZE Phase Output:

{
  "approaches": [
    {
      "name": "Incremental Component Extraction",
      "complexity": "Medium",
      "risk": "Low", 
      "timeEstimate": "30-45 minutes"
    }
  ],
  "recommendation": "Incremental Component Extraction",
  "justification": "Provides best balance of benefits vs. risk",
  "selectedImplementationOrder": [
    "1. Extract form component (lowest risk)",
    "2. Create validation service",
    "3. Refactor main view"
  ]
}

Each phase requires documented analysis and planning before the AI can proceed to implementation.

Tools

Workflow Entry Points

refactor_workflow - Start a structured refactoring process with required analysis and planning phases

create_feature_workflow - Develop new features with integrated testing and documentation requirements

test_workflow - Add test coverage with mandatory analysis of what needs testing

tdd_workflow - Implement Test-Driven Development with enforced Red-Green-Refactor cycles

build_custom_workflow - Create workflows with custom phases and validation requirements

Phase Guidance Tools

• audit_inventory_guidance - Forces thorough code analysis and change cataloging

• compare_analyze_guidance - Requires evaluation of multiple approaches with pros/cons

• question_determine_guidance - Mandates clarification and finalized planning

• phase_output - Validates and records structured outputs from each phase

• workflow_status - Check current progress and validation state

Usage

The server enforces structured workflows through mandatory phases. Each workflow type has different phase requirements:

• Refactor Workflow: AUDIT_INVENTORY → COMPARE_ANALYZE → QUESTION_DETERMINE → WRITE_OR_REFACTOR → LINT → ITERATE → PRESENT

• Feature Workflow: PLANNING → QUESTION_DETERMINE → WRITE_OR_REFACTOR → TEST → LINT → ITERATE → PRESENT

• Test Workflow: AUDIT_INVENTORY → QUESTION_DETERMINE → WRITE_OR_REFACTOR → TEST → ITERATE → PRESENT

• TDD Workflow: PLANNING → WRITE_OR_REFACTOR → TEST → (Red-Green-Refactor cycles) → LINT → PRESENT

Input Validation

The server requires:

• task (string): Description of what you want to accomplish
• outputArtifacts (array): Structured documentation for each completed phase

Output Validation

Each phase completion is validated for:

• Meaningful content length (minimum 10 characters)
• Valid JSON format for structured outputs
• Phase-specific content requirements
• Proper documentation of decisions and analysis

Safety Rule

Files must be read before modification. This prevents accidental data loss and ensures informed changes.

Development

npm run dev      # TypeScript compiler in watch mode  
npm run lint     # Run linter
npm run typecheck # Type checking
npm test         # Run tests

How It Works

1. AI starts a workflow using one of the entry point tools
2. Server creates a session and tracks phase progression
3. Each phase requires specific outputs before proceeding
4. The phase_output tool validates artifacts have meaningful content
5. AI cannot skip phases or claim completion without verified outputs
6. Session state prevents circumventing the structured approach

Testing the MCP Server

You can quickly try out the Structured Workflow MCP server using the test prompts and helper scripts included in this repository.

1. Build the server (if you haven't already):

   npm run build
   

2. Start the server:

   node dist/index.js
   

3. Open the test prompt docs/test_prompt/mcp_server_test_prompt.md in your preferred MCP-compatible AI client and paste the contents.
4. Alternatively, open the sample project located in refactor-test/ for an end-to-end refactor workflow demo. Follow the steps in its README.md to run and observe the structured workflow in action.
5. Watch the AI progress through each phase and verify the structured outputs produced.

Sample Prompts

The docs/sample_prompts directory contains several ready-to-use prompts illustrating typical workflows:

• feature_workflow_prompt.md
• refactor_workflow_prompt.md
• test_workflow_prompt.md
• tdd_workflow_prompt.md
• custom_workflow_prompt.md

Use these as a starting point and adapt them to your projects.

Building

npm install
npm run build

The server uses TypeScript with the @modelcontextprotocol/sdk and runs locally via stdio transport.
