Get started with Code Reviews (original) (raw)

Fast-moving development introduces risk. Code may contain logic errors, security flaws, or performance issues that slip through and reach production.

The kluster.ai Code Reviews service integrates directly into your development workflow, scanning code in real-time. It catches potential issues instantly within your IDE, allowing you to ship code confidently.

Prerequisites＃

Before getting started, ensure you have:

A kluster.ai account: Sign up on the kluster.ai platform if you don't have one.

As kluster.ai services work via MCP, the API key is created and configured for you when setting up the relevant extensions.
