README

Welcome to the Universal MCP Klaviyo API. This project provides a starting point for your API application, generated automatically by MCP CLI to help you kickstart your development quickly.

📋 Prerequisites

Before you begin, ensure you have met the following requirements:

  • Python 3.11+ (Recommended)
  • uv installed globally (pip install uv)

🛠️ Setup Instructions

Follow these steps to get the development environment up and running:

1. Sync Project Dependencies

Navigate to the project root directory (where pyproject.toml is located).

uv sync

This command uses uv to install all dependencies listed in pyproject.toml into a virtual environment (.venv) located in the project root.

2. Activate the Virtual Environment

Activating the virtual environment ensures that you are using the project's specific dependencies and Python interpreter.

  • On Linux/macOS:
source .venv/bin/activate
  • On Windows:
.venv\\Scripts\\activate

3. Start the MCP Inspector

Use the MCP CLI to start the application in development mode.

mcp dev src/universal_mcp_klaviyo/mcp.py

The MCP inspector should now be running. Check the console output for the exact address and port.

🚀 Usage

Once the server is running, you can test the tools and interact with them.
