CodeRabbit

AI-powered code review tool

CodeRabbit is an AI-powered code review tool that automatically reviews pull requests. By connecting Context7 as an MCP server, CodeRabbit can access up-to-date library documentation during reviews, helping it verify implementations against the latest API references and best practices.

Setup

1. Navigate to MCP Servers

   Go to your CodeRabbit dashboard and navigate to Integrations → MCP Servers.

   
2. Add Context7

   Click the Add button next to Context7 MCP server.

   Add the following header for higher rate limits:

   Header	Value
   CONTEXT7_API_KEY	Your API key from the Context7 dashboard

   {
     "CONTEXT7_API_KEY": "YOUR_API_KEY"
   }
   

   
3. Connect

   Click the Connect button to connect the server.

   
4. Enable for Public Repos

   To use Context7 with public repositories, go to Organization Settings → Configuration → Knowledge Base. In the MCP section, select Enabled instead of Auto and click Apply Changes.

   

Usage Guidance

In the Usage Guidance field, you can instruct CodeRabbit on how to use Context7 during reviews. For example:

Use Context7 to look up documentation for any libraries used in the code being reviewed.
Verify that API usage matches the latest documentation and flag any deprecated patterns.

How It Works

Once connected, CodeRabbit will query Context7 for relevant library documentation when reviewing pull requests. This helps CodeRabbit:

• Verify correct API usage against the latest documentation
• Identify deprecated methods or patterns
• Suggest improvements based on library best practices
• Provide more accurate and informed review comments
