A Model Context Protocol (MCP) server that brings **GDPR compliance knowledge directly into your IDE**, enabling developers and compliance teams to "shift left" — identifying and addressing data protection requirements early in the development lifecycle.

> **⚠️ Disclaimer:** This tool provides informational guidance only and **does not constitute legal advice**. Organisations should consult qualified legal counsel for binding GDPR compliance decisions.

## Quick Start

### Prerequisites
- Python 3.10+
- VS Code with GitHub Copilot

### Installation

```bash
# Clone the repository
git clone https://github.com/KevinRabun/GDPRShiftLeftMCP.git
cd GDPRShiftLeftMCP

# Install in development mode
pip install -e ".[dev]"
```

### VS Code Integration

The repository includes `.vscode/mcp.json` for automatic MCP server registration. After installation, the GDPR tools appear in GitHub Copilot's tool list.

To configure manually, add to your VS Code settings:

```json
{
  "mcp": {
    "servers": {
      "gdpr-shift-left-mcp": {
        "type": "stdio",
        "command": "python",
        "args": ["-m", "gdpr_shift_left_mcp"]
      }
    }
  }
}
```

### Running the Server

```bash
# Run directly
python -m gdpr_shift_left_mcp

# Or via the installed entry point
gdpr-shift-left-mcp
```

## Online Updates

The server fetches GDPR data from a configurable online source, with local caching:

- **Source URL:** Set via `GDPR_SOURCE_URL` environment variable
- **Cache TTL:** Default 1 hour (configurable via `GDPR_CACHE_TTL`)
- **Cache directory:** `__gdpr_cache__/` (configurable via `GDPR_CACHE_DIR`)
- **Fallback:** Built-in data if online fetch fails
