Why Anchor Stack?

Have you ever experienced this?

"AI helped me write the code, but debugging took longer than writing it myself..."

The problem isn't the AI - it's that your project wasn't designed for AI collaboration.

Anchor Stack solves this by creating projects that are:

Problem	Solution
Inconsistent logging	Standardized logger module - AI knows exactly how to add logs
Environment chaos	Type-safe config module - no more process.env everywhere
Version conflicts	Curated dependency versions - tested and stable
AI confusion	Rules files that teach AI your project conventions

Features

• Stable Stacks - Curated technology stacks with version-locked dependencies
• Unified Logging - Standardized logging framework that AI understands
• AI Rules - Auto-generated rules for Claude, Cursor, Windsurf, and more
• Pluggable Packs - Add database, AI, auth capabilities on demand
• MCP Native - Works seamlessly with MCP-compatible AI tools

Quick Start

Installation

# Using pip
pip install anchor-stack

# Using uv (recommended)
uv pip install anchor-stack

Configure Your AI Tool

Claude Desktop

Edit %APPDATA%\Claude\claude_desktop_config.json (Windows) or ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "anchor-stack": {
      "command": "anchor-stack",
      "args": ["serve"]
    }
  }
}

Cursor

Edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "anchor-stack": {
      "command": "anchor-stack",
      "args": ["serve"]
    }
  }
}

VS Code (Copilot)

Edit .vscode/settings.json:

{
  "mcp": {
    "servers": {
      "anchor-stack": {
        "command": "anchor-stack",
        "args": ["serve"]
      }
    }
  }
}

Create Your First Project

Simply ask your AI assistant:

Create a Next.js project called "my-app" using Anchor Stack

The AI will use scaffold_project to create:

my-app/
├── src/
│   ├── app/              # Next.js App Router
│   ├── components/       # React components
│   ├── lib/
│   │   ├── core/         # Logger & Config (DO NOT MODIFY)
│   │   └── utils/        # Utility functions
│   └── services/         # Business logic
├── CLAUDE.md             # Rules for Claude
├── .cursor/rules/        # Rules for Cursor
├── .windsurfrules        # Rules for Windsurf
└── anchor.config.json    # Project metadata

Available Tools

scaffold_project

Create a new project from a Stack template.

scaffold_project({
  stack_name: "nextjs",        // Stack type
  project_name: "my-app",      // Project name
  target_dir: "/path/to/dir"   // Target directory
})

add_pack

Add a capability pack to an existing project.

add_pack({
  project_dir: "/path/to/project",
  pack_name: "database-postgres"
})

doctor

Check project health and configuration.

doctor({
  project_dir: "/path/to/project"
})

1. You ask your AI to create a project
2. AI calls Anchor Stack's MCP tools
3. Anchor Stack generates files with proper structure
4. AI Rules help future AI interactions understand your project
