MCP servers are used to integrate AI agents into software applications for system-related tasks, and platforms like Slack, Sentry, Notion, and GitHub Copilot have adopted this approach to enhance their features. CodeRabbit acts as an MCP client, enabling users to perform enhanced code reviews by incorporating context from multiple sources, including Slack, Confluence, and CI/CD pipelines. This tutorial guides users through setting up a Slack MCP server and connecting it to CodeRabbit, allowing the AI code review platform to access and utilize Slack channel data for more precise and context-aware reviews. The integration process involves configuring a Slack MCP server locally using Claude Desktop, hosting it via Docker, and generating a public URL with ngrok for CodeRabbit access. By doing so, CodeRabbit can enrich code reviews with additional context, ensuring alignment with project goals and making reviews more insightful and actionable.
