Structured Workflow MCP

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 got tired of repeating "inventory and audit first" across every AI platform and prompt, so I built an MCP server that automatically enforces this disciplined approach. It forces AI to think systematically and follow structured phases instead of jumping straight into code changes.

So I've built an MCP server that fits into my workflow and thinking process while I'm programming. I made it available via npx and you can download it yourself if you want something local.

In essence I was doing some repeated tasks with AI where I wanted it to complete refactoring work for part of a larger project. I was struggling because it was often missing or glossing over key things: classes or systems that already exist (a preferences service for example), creating duplicates of things, or when correcting mistakes, leaving orphaned unused methods/code around places, and when writing tests it would often pull in the wrong imports or put these together in the wrong way resulting in syntax errors but would jump straight into writing the next test without fixing the first one that was broken.

I sort of stumbled on this idea of the model needing to perform an audit and inventory of the current project (or not even the whole project--just one layer or feature in a project) before moving to any kind of implementation phase and it needed a lint iterate lint phase. I tried this with rules with limited success and then prompting with much better success but I was constantly repeating myself.

So I started noodling on this idea of an MCP server that forced the AI to work through a problem in phases or lanes. So that's what this does. There's a number of different workflow styles and I'm open to any other ideas or improvements.

Feel free to check it out if it helps your use case. It's a work in progress but it has been doing a pretty great job for what I'm using it for now. Happy to share more if you are interested.

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

How It Works

Here's how the AI moves through a structured workflow:

What happens at each step:

1. Start Workflow - AI calls a workflow tool (refactor_workflow, create_feature_workflow, etc.)
2. AI Gets Phase Guidance - Server provides specific instructions for current phase (audit, analyze, implement, etc.)
3. Create Phase Output - AI works through the phase and creates documentation/artifacts
4. Auto-Save - Files are automatically saved with numbered naming in task directories
5. Phase Validation - Server validates outputs meet requirements before proceeding
6. Next Phase - Process repeats until workflow is complete

File Output & Configuration

Automatic File Creation

The server automatically creates numbered workflow files as you progress through phases:

Configuration Options

Default Behavior: Files are saved to ./structured-workflow/[task-name]/ in your current directory.

Custom Output Directory: Configure where files are created by adding CLI parameters to your MCP server config:

Available CLI Parameters:

• --output-dir <path> - Set custom output directory (default: structured-workflow)
• --working-dir <path> - Set working directory for the server
• --help - Show help message

Graceful Fallback: If file creation fails (permissions, disk space), the server continues with validation-only mode - your workflow isn't interrupted.

Installation

Quick Start (Recommended) - Zero Installation

Add to your AI assistant config - Uses npx automatically:

💡 Note: I recommend using @latest to ensure you always get the newest features and fixes. Without @latest, npx may cache older versions.

VS Code / Cursor / Windsurf - Add to your MCP settings:

With custom output directory:

Claude Desktop - Add to your claude_desktop_config.json:

With custom output directory:

Global Installation (Optional)

You can install globally on your machine using NPM:

Then use in your AI assistant config:

With custom output directory:

Auto-Install via Smithery

Smithery provides a number of ways to install directly into your apps including this way for Claude Desktop:

Manual Installation

For developers, you can clone the repository and build it locally:

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:

COMPARE_ANALYZE Phase Output:

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

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

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