MCP server for DAG-based workflow execution with YAML definitions and LLM collaboration

Workflows MCP

Automate anything with simple YAML workflows for your AI assistant.

Workflows MCP is a Model Context Protocol (MCP) server that lets you define powerful, reusable automation workflows in YAML and execute them through AI assistants like Claude. Think of it as GitHub Actions for your AI assistant—define your automation once, run it anywhere.

What Does This Give Me?

Workflows MCP transforms your AI assistant into an automation powerhouse. Instead of manually running commands or writing repetitive scripts, you define workflows in YAML, and your AI assistant executes them for you.

Real-world example:

You: "Run the Python CI pipeline on my project"
Claude: *Executes workflow that sets up environment, runs linting, and runs tests*
Claude: "✓ All checks passed! Linting: ✓, Tests: ✓, Coverage: 92%"

---

Why Should I Use This?

For Non-Technical Users

• No coding required - Define automation in simple YAML
• Reusable templates - Use pre-built workflows for common tasks
• AI-powered execution - Just ask your AI assistant in plain English

For Developers

• DRY principle - Define once, use everywhere
• Parallel execution - Automatic optimization of independent tasks
• Type-safe - Validated inputs and outputs
• Composable - Build complex workflows from simple building blocks

For Teams

• Shared automation - Version control your workflows
• Consistent processes - Everyone uses the same tested workflows
• Custom templates - Build company-specific automation libraries

---

Quick Start

Step 1: Install

Choose one of these installation methods:

Option A: Using uv (Recommended - Faster)

uv pip install workflows-mcp

Option B: Using pip

pip install workflows-mcp

Requirements:

• Python 3.12 or higher
• That's it!

Step 2: Configure Your AI Assistant

For Claude Desktop or Claude Code

Method 1: QTS Marketplace (Easiest)

Install the complete workflows plugin with agent, skills, and auto-configuration:

# Add the marketplace (one-time setup)
/plugin marketplace add qtsone/marketplace

# Install the workflows plugin
/plugin install workflows@qtsone

This automatically configures the MCP server to look for custom workflows in ~/.workflows and ./.workflows (optional directories you can create if you want to add custom workflows).

Method 2: Manual Configuration

Add this to your Claude Desktop config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "workflows": {
      "command": "uvx",
      "args": ["workflows-mcp", "--refresh"],
      "env": {
        "WORKFLOWS_TEMPLATE_PATHS": "~/.workflows,./.workflows"
      }
    }
  }
}

Note: The WORKFLOWS_TEMPLATE_PATHS directories are optional. Only create them if you want to add custom workflows. The server works perfectly fine with just the built-in workflows. We recommend using ~/.workflows as it's also the default location for optional LLM configuration (llm-config.yml).

For Other MCP-Compatible AI Assistants

The configuration is similar. For example, Gemini CLI users would add this to ~/.gemini/settings.json with the same structure.

Step 3: Restart and Test

1. Restart your AI assistant (e.g., Claude Desktop)
2. Try it out:

You: "List all available workflows"

Your AI assistant will show you all the built-in workflows ready to use!

---

How It Works

Workflows MCP operates on three simple concepts:

1. Workflows (The What)

YAML files that define what you want to automate. Each workflow has:

• Inputs - Parameters users can customize
• Blocks - Individual tasks to execute
• Outputs - Results returned to the user

2. Blocks (The How)

Individual tasks within a workflow. Available block types:

• Shell - Run shell commands
• LLMCall - Call AI/LLM APIs
• HttpCall - Make HTTP requests
• CreateFile, ReadFiles, EditFile - File operations
• Workflow - Call other workflows (composition)
• Prompt - Interactive user prompts
• ImageGen - Generate and edit images (DALL-E, Stable Diffusion)
• ReadJSONState, WriteJSONState, MergeJSONState - State management

3. Execution (The Magic)

The server automatically:

• Analyzes dependencies between blocks
• Runs independent blocks in parallel
• Handles errors gracefully
• Substitutes variables dynamically

Example Flow:

# Python CI Pipeline
setup_env → run_linting ↘
                         → validate_results
setup_env → run_tests   ↗

Tasks run in parallel when possible, saving time!

---

What Can I Build?

The possibilities are endless. Here are some examples:

Development Automation

• CI/CD Pipelines - Automated testing, linting, building
• Code Quality Checks - Run multiple linters and formatters in parallel
• Deployment Workflows - Build, test, and deploy applications

Git Operations

• Smart Branch Management - Create feature branches with proper naming
• Automated Commits - Stage files and commit with generated messages
• Repository Analysis - Analyze changes, detect patterns

Data Processing

• File Transformations - Process and transform files in batch
• API Orchestration - Chain multiple API calls together
• Report Generation - Generate reports from templates

AI-Powered Tasks

• Content Analysis - Use LLMs to analyze and extract insights
• Code Generation - Generate code based on specifications
• Automated Review - Review code, documents, or data

---

Creating Your First Workflow

Let's create a simple workflow that greets a user:

1. Create a YAML file

First, create the workflows directory (if it doesn't exist):

mkdir -p ~/.workflows

Then save this as ~/.workflows/greet-user.yaml:

name: greet-user
description: A friendly greeting workflow
tags: [example, greeting]

inputs:
  name:
    type: str
    description: Name of the person to greet
    default: "World"

  language:
    type: str
    description: Language for greeting (en, es, fr)
    default: "en"

blocks:
  - id: create_greeting
    type: Shell
    inputs:
      command: |
        case "{{inputs.language}}" in
          es) echo "¡Hola, {{inputs.name}}!" ;;
          fr) echo "Bonjour, {{inputs.name}}!" ;;
          *) echo "Hello, {{inputs.name}}!" ;;
        esac

outputs:
  greeting:
    value: "{{blocks.create_greeting.outputs.stdout}}"
    type: str
    description: The personalized greeting

2. Restart your AI assistant

The workflow is automatically discovered from ~/.workflows/

3. Use it!

You: "Run the greet-user workflow with name=Alice and language=es"
Claude: *Executes workflow*
Claude: "¡Hola, Alice!"

Understanding the Workflow

• inputs - Define customizable parameters
• blocks - Each block is a task (here, running a shell command)
• {{inputs.name}} - Variable substitution (replaced at runtime)
• outputs - What gets returned to the user

Key Features

🚀 Smart Parallel Execution

The server automatically detects which tasks can run in parallel. Use depends_on to specify dependencies—independent tasks run concurrently for maximum efficiency.

See examples: tests/workflows/core/dag-execution/parallel-execution.yaml

🔐 Secure Secrets Management

Store sensitive data like API keys securely using environment variables. Secrets are resolved server-side and never exposed to the LLM context.

{
  "mcpServers": {
    "workflows": {
      "env": {
        "WORKFLOW_SECRET_GITHUB_TOKEN": "ghp_your_token_here",
        "WORKFLOW_SECRET_OPENAI_API_KEY": "sk-your_key_here"
      }
    }
  }
}

Use in workflows: {{secrets.GITHUB_TOKEN}}

Security features:

• ✅ Secrets never appear in LLM context
• ✅ Automatic redaction in all outputs
• ✅ Server-side resolution only
• ✅ Fail-fast on missing secrets

See examples: tests/workflows/core/secrets/

🎨 Full Jinja2 Template Support

All workflow fields are Jinja2 templates with support for:

• Variable expressions: {{inputs.name}}, {{blocks.test.outputs.result}}
• Control structures: {% if condition %}...{% endif %}, {% for item in list %}...{% endfor %}
• Custom filters: quote, prettyjson, b64encode, hash, trim, upper, lower, replace
• Global functions: now(), render(), get(), len(), range()
• Filter chaining: {{inputs.text | trim | lower | replace(' ', '_')}}

See examples: tests/workflows/core/filters/filters-chaining.yaml

📂 ReadFiles Block with Outline Extraction

Read files with glob patterns, multiple output modes, and automatic outline extraction:

Features:

• Glob pattern support (*.py, **/*.ts)
• Three output modes:
  • full - Complete file content
  • outline - Structural outline (90-97% context reduction for Python/Markdown)
  • summary - Outline + docstrings/comments
• Gitignore integration and file filtering
• Size limits and file count limits
• Multi-file reading in single block
• Smart output format:
  • Single file: Direct content (string)
  • Multiple files: YAML-formatted structure
  • No files: Empty string

See examples: tests/workflows/core/file-operations/readfiles-test.yaml

✏️ Deterministic File Editing

The EditFile block provides powerful deterministic file editing with multiple operation strategies:

Features:

• 6 operation types (replace_text, replace_lines, insert_lines, delete_lines, patch, regex_replace)
• Atomic transactions (all-or-nothing by default)
• Automatic backup creation before editing
• Dry-run mode for previewing changes
• Comprehensive diff generation
• Path traversal protection

See examples: tests/workflows/core/file-operations/editfile-operations-test.yaml

🤖 LLM Integration

Call AI models directly from workflows with automatic retry and validation. Configure providers using ~/.workflows/llm-config.yml (optional).

Supported providers: OpenAI, Anthropic, Gemini, Ollama, OpenAI-compatible (LM Studio, vLLM)

Example:

- id: analyze
  type: LLMCall
  inputs:
    profile: default  # Existing profile from ~/.workflows/llm-config.yml
    prompt: "Analyze this text: {{inputs.text}}"
    response_schema:
      type: object
      required: [sentiment, summary]
      properties:
        sentiment:
          type: string
          enum: [positive, negative, neutral]
        summary:
          type: string

Profile Fallback for Portable Workflows:

When a workflow requests a profile that doesn't exist in your config, the system automatically falls back to default_profile with a warning. This enables workflow portability - authors can write workflows with semantic profile names (like cloud-mini, cloud-thinking, local) without requiring specific user configurations.

# ~/.workflows/llm-config.yml
profiles:
  my-model:
    provider: openai-cloud
    model: gpt-4o
    max_tokens: 4000

default_profile: my-model

🎨 Image Generation

Generate, edit, and create variations of images using OpenAI DALL-E or compatible providers (like local Stable Diffusion via OpenAI-compatible API).

Key Features:

• Model Capability System: Automatic validation of operations and parameters based on model support
• Profile Support: Use ~/.workflows/llm-config.yml to manage providers and models (same as LLMCall)
• Direct File Saving: Save generated images directly to disk with output_file
• Pluggable Providers: Support for OpenAI (DALL-E 2/3) and any OpenAI-compatible image API

Model Compatibility:

The executor validates operations and parameters based on model capabilities:

Model	Generate	Edit	Variation	Optional Parameters
dall-e-3	✓	✗	✗	response_format, quality, style
dall-e-2	✓	✓	✓	response_format
gpt-image-1	✓	✓	✗	None
gpt-image-*	✓	✓	✗	None

The executor automatically filters parameters and provides clear error messages when operations are not supported.

Configuration:

Input	Description	Default
prompt	Text description (required for generate/edit)	-
profile	Profile name from config (recommended)	default
operation	generate, edit, or variation	generate
model	Model name (e.g., dall-e-3)	dall-e-3
size	Image dimensions (e.g., 1024x1024)	1024x1024
quality	standard or hd (dall-e-3 only)	standard
style	vivid or natural (dall-e-3 only)	vivid
response_format	url or b64_json	url
n	Number of images to generate	1
output_file	Path to save image (e.g., {{tmp}}/img.png)	-
image	Path to base image (for edit/variation)	-
mask	Path to mask image (transparent areas define where to edit)	-

Examples:

1. Basic Generation (using profile):

- id: generate_art
  type: ImageGen
  inputs:
    prompt: "A cyberpunk city at night"
    profile: default
    size: "1024x1024"
    output_file: "{{tmp}}/city.png"

2. Image Editing with DALL-E 2:

- id: edit_photo
  type: ImageGen
  inputs:
    operation: edit
    model: dall-e-2  # DALL-E 3 does not support edit
    prompt: "Add a red hat to the person"
    image: "/path/to/photo.png"
    mask: "/path/to/mask.png"
    output_file: "{{tmp}}/edited.png"

3. Using Custom Provider (e.g., Local SD):

- id: local_gen
  type: ImageGen
  inputs:
    prompt: "A medieval castle"
    provider: openai_compatible
    api_url: "http://localhost:8000/v1"
    model: "sd-xl"
    output_file: "{{tmp}}/castle.png"

🔁 Universal Iteration (for_each)

Iterate over collections with ANY block type using for_each. Supports parallel and sequential execution modes with error handling.

Iteration variables:

• {{each.key}} - Current key
• {{each.value}} - Current value
• {{each.index}} - Zero-based position
• {{each.count}} - Total iterations

See examples: tests/workflows/core/for_each/for-each-comprehensive.yaml

🔄 Workflow Composition

Build complex workflows from simple reusable pieces using the Workflow block type. Supports recursion with configurable depth limits.

See examples: tests/workflows/core/composition/

📝 Conditional Execution

Run blocks only when conditions are met using the condition field. Conditions are evaluated as Jinja2 expressions.

See examples: tests/workflows/core/conditionals/

💬 Interactive Workflows

Pause workflows to get user input using the Prompt block. Use resume_workflow(job_id, response) to continue execution with the user's input.

See examples: tests/workflows/interactive-simple-approval.yaml

⚡ Async Execution

Execute long-running workflows without blocking using mode="async". Track progress with get_job_status(job_id) and cancel with cancel_job(job_id).

Use cases:

• Long CI/CD pipelines
• Large-scale data processing
• Multi-stage deployments
• Resource-intensive analysis

---

Built-in Workflows

The server includes many ready-to-use workflows for common tasks.

📋 Quality & Testing

Core workflows (Python CI, Git operations, file operations) are actively used and thoroughly tested. Some advanced workflows are still being refined.

Best practice: Always inspect a workflow before using it (get_workflow_info tool) and test on non-production systems first.

Battle-tested examples: The workflows in tests/workflows/core/ are comprehensively tested in CI and demonstrate all core features reliably.

Discovering Workflows

List all workflows:

You: "List all available workflows"

Get detailed information:

You: "Show me details about the python-ci-pipeline workflow"

Filter by category:

You: "List workflows tagged with 'python'"
You: "Show me all git workflows"

Popular workflows include: Python CI pipelines, Git operations (checkout, commit, status), linting tools, test runners, and file operations.

---

      "command": "uvx",
      "args": ["workflows-mcp", "--refresh"],
      "env": {
        "WORKFLOWS_TEMPLATE_PATHS": "~/.workflows,./project-workflows",
        "WORKFLOWS_LOG_LEVEL": "DEBUG",
        "WORKFLOWS_MAX_RECURSION_DEPTH": "100",
        "WORKFLOWS_IO_QUEUE_ENABLED": "true",
        "WORKFLOWS_JOB_QUEUE_ENABLED": "true",
        "WORKFLOWS_JOB_QUEUE_WORKERS": "5",
        "WORKFLOWS_MAX_CONCURRENT_JOBS": "200",
        "WORKFLOW_SECRET_GITHUB_TOKEN": "ghp_xxxxx",
        "WORKFLOW_SECRET_OPENAI_API_KEY": "sk-xxxxx"
      }
    }
  }
}

Custom Workflow Directories

The server loads workflows from:

1. Built-in templates (always loaded)
2. Custom directories (specified in WORKFLOWS_TEMPLATE_PATHS, optional)

Note: Custom workflow directories are not created automatically. You need to create them manually if you want to add your own workflows. The server works fine without them using only built-in workflows.

Load order priority: Later directories override earlier ones by workflow name.

---

Examples

For comprehensive examples demonstrating all features, see the test workflows in tests/workflows/core/:

• File operations: tests/workflows/core/file-operations/
• Parallel execution: tests/workflows/core/dag-execution/
• Conditionals: tests/workflows/core/conditionals/
• Composition: tests/workflows/core/composition/
• Secrets: tests/workflows/core/secrets/
• Filters: tests/workflows/core/filters/
• Iteration: tests/workflows/core/for_each/

Quick Example: Simple Shell Command

name: disk-usage
description: Check disk usage
tags: [utility, system]

blocks:
  - id: check_disk
    type: Shell
    inputs:
      command: "df -h"

outputs:
  disk_info:
    value: "{{blocks.check_disk.outputs.stdout}}"
    type: str

Troubleshooting

Installation Issues

Problem: command not found: workflows-mcp

Solution:

# Ensure Python 3.12+ is installed
python --version  # Should be 3.12 or higher

# Reinstall with uv
uv pip install --force-reinstall workflows-mcp

# Or verify installation
pip show workflows-mcp

Problem: Python version too old

Solution:

# Install Python 3.12+ using your package manager
# macOS (Homebrew)
brew install python@3.12

# Ubuntu/Debian
sudo apt install python3.12

# Update uv to use Python 3.12
uv venv --python 3.12

Configuration Issues

Problem: Workflows not loading in Claude

Solution:

1. Verify config file location (see Quick Start)
2. Check JSON syntax with a validator
3. Restart Claude Desktop completely
4. Check Claude Desktop logs:
   • macOS: ~/Library/Logs/Claude/
   • Windows: %APPDATA%\Claude\logs\

Problem: Custom workflows not found

Solution:

# First, make sure you created the directory
mkdir -p ~/.workflows

# Verify WORKFLOWS_TEMPLATE_PATHS is correct
# Paths should exist and contain .yaml files

# Check directory exists and contains workflows
ls ~/.workflows/

# Check YAML syntax
python -c "import yaml; yaml.safe_load(open('~/.workflows/my-workflow.yaml'))"

Workflow Execution Issues

Problem: Workflow fails with "not found" error

Solution:

You: "List all workflows"
# This shows exact workflow names
# Use the exact name from the list

Problem: Variables not substituting

Solution:

• Check syntax: {{inputs.name}} not {inputs.name}
• Ensure input is defined in inputs: section
• For block outputs: {{blocks.block_id.outputs.field_name}}

Problem: Secrets not working

Solution:

1. Check environment variable name: WORKFLOW_SECRET_<NAME>
2. Reference in workflow: {{secrets.NAME}} (without prefix)
3. Verify secrets are in MCP server config, not workflow YAML
4. Restart MCP server after adding secrets

Performance Issues

Problem: Workflows running slowly

Solution:

• Check if tasks can run in parallel (remove unnecessary depends_on)

• Enable debug logging to see execution waves:

  You: "Run workflow X with debug=true"
  

• Review task dependencies—too many serialized tasks slow execution

Problem: Shell commands timing out

Solution:

blocks:
  - id: long_task
    type: Shell
    inputs:
      command: "./long-script.sh"
      timeout: 600  # Increase timeout (default: 120 seconds)

Debug Mode

Enable detailed logging for troubleshooting:

Method 1: Environment variable

{
  "mcpServers": {
    "workflows": {
      "env": {
        "WORKFLOWS_LOG_LEVEL": "DEBUG"
      }
    }
  }
}

Method 2: Per-execution debug

You: "Run python-ci-pipeline with debug=true"

Debug logs are written to /tmp/<workflow>-<timestamp>.json with:

• Block execution details
• Variable resolution steps
• DAG wave analysis
• Timing information

---

Architecture

Workflows MCP uses a fractal execution model where workflows and blocks share the same execution context structure. This enables clean composition and recursive workflows.

Key Components

• WorkflowRunner - Orchestrates workflow execution
• BlockOrchestrator - Executes individual blocks with error handling
• DAGResolver - Resolves dependencies and computes parallel execution waves
• UnifiedVariableResolver - Jinja2-based variable resolution with four namespaces:
  • inputs - Workflow runtime inputs
  • blocks - Block outputs and metadata
  • metadata - Workflow metadata
  • secrets - Server-side secrets (never exposed to LLM)

Execution Model

Workflows execute in waves—groups of blocks that can run in parallel:

Wave 1: [setup]
Wave 2: [lint, test]      ← Parallel execution
Wave 3: [validate]

This maximizes efficiency by running independent tasks concurrently.

FAQ

Do I need to know Python to use this?

No! You only need to:

1. Install the package (one command)
2. Configure your AI assistant (copy-paste JSON)
3. Write simple YAML workflows (or use built-in ones)

Do I need to know what MCP is?

No! Just think of it as a way for your AI assistant to run workflows. The technical details are handled for you.

Can I use this without Claude?

Yes! Any MCP-compatible AI assistant can use workflows-mcp. The configuration is similar across different assistants.

Are workflows secure?

Yes! The server includes:

• Server-side secret resolution (secrets never reach the AI)
• Automatic redaction of sensitive data
• Sandboxed execution contexts
• Audit logging

Are all built-in workflows production-ready?

The core workflows (Python CI, Git operations, basic file operations) are actively used and reliable. Some advanced workflows are still being refined and tested.

Best practice: Always inspect a workflow before using it (get_workflow_info tool) and test on non-production systems first. The workflows in tests/workflows/ are thoroughly tested in CI and are great examples to learn from.

Can I share workflows with my team?

Absolutely! Workflows are just YAML files. You can:

• Commit them to version control
• Share them in a company repository
• Publish them as packages

What's the performance like?

Excellent! The DAG-based execution model automatically parallelizes independent tasks. Many users see 2-3x speedup compared to sequential execution.

Can workflows call other workflows?

Yes! Use the Workflow block type to compose workflows. Recursion is supported with configurable depth limits.
