project-scaffold

An MCP server that scaffolds full-stack projects with consistent structure, Docker setup, CI/CD pipelines, and database configuration. Built with FastMCP.

Alpha — This project is under active development. APIs and generated output may change between versions. Contributions are welcome! See CONTRIBUTING.md.

What it generates

Every scaffolded project comes with:

• FastAPI backend with async SQLAlchemy and Pydantic v2

• PostgreSQL database with Docker Compose (includes pgAdmin)

• Frontend — React (Vite + TypeScript) or HTMX (Tailwind CSS)

• Alembic database migrations (optional)

• JWT authentication boilerplate (optional)

• CI/CD — GitHub Actions for Azure, or Render.com blueprint

• Makefile with common dev commands

Template combinations

Requirements

• Python 3.12+

• uv (recommended) or pip

Installation

From GitHub (pip)

pip install git+https://github.com/dawiegriesel/mcp-dev.git

From GitHub (uv)

uv pip install git+https://github.com/dawiegriesel/mcp-dev.git

Local development

git clone https://github.com/dawiegriesel/mcp-dev.git
cd mcp-dev
uv sync

For development dependencies (pytest, ruff):

uv sync --extra dev

Installing the MCP server

Claude Code

claude mcp add project-scaffold -- uvx --from "git+https://github.com/dawiegriesel/mcp-dev.git" project-scaffold

Or if installed locally:

claude mcp add project-scaffold -- uv run --directory /path/to/mcp-dev project-scaffold

Project-scoped config (local development)

For local development, create a .mcp.json in the repo root to register the server automatically when you open the repo in Claude Code — no manual claude mcp add needed:

{
  "mcpServers": {
    "project-scaffold": {
      "command": "uv",
      "args": ["run", "--directory", "/your/local/path/mcp-dev", "project-scaffold"]
    }
  }
}

Replace the --directory value with your actual clone path. This file is gitignored to avoid committing local paths.

Claude Desktop

Add this to your Claude Desktop config file (~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "project-scaffold": {
      "command": "uvx",
      "args": [
        "--from", "git+https://github.com/dawiegriesel/mcp-dev.git",
        "project-scaffold"
      ]
    }
  }
}

Other MCP clients

Run the server with stdio transport (the default):

project-scaffold

Or without installing:

uvx --from "git+https://github.com/dawiegriesel/mcp-dev.git" project-scaffold

MCP tools

The server exposes five tools via MCP:

list_templates

Returns all available project template combinations and their default stack.

create_project

Scaffolds a complete project. Configuration options:

add_component

Adds a component to an existing scaffolded project. Supported components:

• api_router — FastAPI router with full CRUD endpoints, plus auto-generated model and schema if fields are provided

• db_model — SQLAlchemy model with matching Pydantic schemas

Components not yet implemented: frontend_page, github_action, docker_service.

validate_project

Checks that a scaffolded project has all expected files. Reports any missing files.

get_project_info

Reads the .scaffold.json metadata from an existing project and returns its configuration.

Example prompts

Once the MCP server is installed, you can use natural language to scaffold and extend projects. Here are some example prompts to get started:

Scaffold a new project

Create a new personal project called "recipe-box" with an HTMX frontend. Put it in ~/projects. Include auth and migrations.

Scaffold a work project named "inventory-tracker" with a React frontend in ~/work. No auth needed but include Alembic.

I want to start a new side project called "budget-app". It should be a simple server-rendered app I can deploy to Render. Create it in ~/dev.

What project templates are available?

Add components to an existing project

Add a "products" API router to my project at ~/projects/recipe-box with fields: title (str), prep_time (int), servings (int), instructions (text).

Add a database model called "category" with fields name (str) and description (text) to ~/projects/recipe-box.

I need a new "orders" endpoint in my inventory-tracker project. It should have fields for customer_name (str), total (float), and fulfilled (bool).

Inspect and validate projects

Check if my project at ~/projects/recipe-box has all the expected files.

What's the configuration for the project in ~/work/inventory-tracker?

Validate the project structure at ~/dev/budget-app and tell me if anything is missing.

Automated documentation updates

This repo includes a docs-pre-commit Claude agent (.claude/agents/docs-pre-commit.md). When working in Claude Code, it triggers automatically before commits to update CHANGELOG.md, README.md, and CLAUDE.md to reflect the changes being committed.

To trigger it manually, tell Claude: "Update the documentation before I commit."
