What's New in CodeRabbit: Late August to Mid-September 2025 Edition

The past few weeks have been huge for CodeRabbit! We've launched our most requested feature, CodeRabbit CLI, and rolled out powerful configuration management tools that give you more control over your review workflows.

We're also proud to announce a $1 million USD commitment to open source software sponsorships! This commitment reflects both our gratitude for what open source makes possible and our belief in the importance of investing in its future!

Here's everything we shipped from late August to mid-September 2025:

MCP Server Integration (Sep 17)

You can now connect CodeRabbit with MCP servers to bring in extra context from your development tools. This means reviews can take into account more than just the code, things like docs, tickets, and internal wikis.

What this lets you do:

Link CodeRabbit to docs, project management tools, and wikis
Give reviewers (and AI) the bigger picture behind your code
Get feedback that considers business logic and requirements, not just syntax

How it works:

When CodeRabbit runs a review, it can pull in relevant context from these sources, similar to how a teammate would check docs or specs before giving feedback.

CodeRabbit CLI - Beta (Sep 16)

AI code reviews are now available in your terminal. CodeRabbit CLI delivers the same intelligent analysis that catches production bugs in our VS Code extension, optimized for command-line workflows and AI agent integration.

What's new:

Get code reviews on uncommitted changes without leaving your terminal
Catches race conditions, memory leaks, and security vulnerabilities that traditional linters miss
Optimized for AI agent integration
Free to use with rate limits
Perfect for developers who live in the terminal

Username-based PR Review Control (Aug 27)

Introducing username-based PR review control. Automatically skip reviews for pull requests created by specific users. Whether you want to exclude automated bots, service accounts, or specific team members, you can now easily configure CodeRabbit to skip these reviews silently.

What you can do:

Add Git provider usernames to your configuration file under the ignore_usernames array
CodeRabbit automatically skips reviews for those users without posting any comments
Works alongside existing label-based controls for maximum flexibility
Configure once and let the system handle automated exclusions

This gives you precise control over your automated review workflow, ensuring reviews happen exactly when and where you need them most.

Central Configuration Repository (Aug 22)

Keeping CodeRabbit settings in sync across multiple repos just got easier. You can now manage all your configurations from one central repository instead of updating each project separately.

What this means:
