GDPR Shift-Left MCP Server

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

Install from the MCP Registry (recommended)

The server is published to the MCP Registry. You can install it directly in VS Code:

1. Open the Extensions view (Ctrl+Shift+X)
2. Type @mcp GDPR in the search field
3. Click Install on "GDPR Shift-Left Compliance"

Note: The VS Code MCP gallery shows a curated subset of servers by default. If the server doesn't appear, add this to your VS Code User Settings (Ctrl+, → Open Settings JSON):

"chat.mcp.gallery.serviceUrl": "https://registry.modelcontextprotocol.io"

This points VS Code at the full MCP Registry (5,000+ servers) instead of GitHub's curated list.

Install via uvx (no clone needed)

uvx gdpr-shift-left-mcp

Install from source

# 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:

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

Running the Server

# 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

Contributing

See CONTRIBUTING.md for guidelines. This project follows Git Flow branching:

• feature/<name> for new features
• bugfix/<name> for fixes
• release/<version> for releases
• hotfix/<name> for production fixes

All PRs must pass automated tests and judges before merging.
