Cursor Bugbot Adds Learned Rules, MCP Support
TL;DR
Bugbot learns custom rules from PR feedback and uses MCP servers for extra context in code reviews.
Cursor has updated its Bugbot feature to include learned rules and Model Context Protocol support. Bugbot now analyzes your past pull request feedback to automatically apply those lessons to future code reviews. This means the AI understands your specific coding standards and preferences without you needing to repeat instructions for every new task. The addition of MCP support allows the tool to connect to external data sources and internal systems to provide more accurate context during the review process. You can now pull in documentation, logs, or database schemas directly into the review workflow to help the AI spot errors that were previously invisible. If you are building software, this update reduces the time spent on manual code review and helps maintain consistency across your codebase. Start by reviewing your recent pull request comments to ensure the AI has a clear baseline for your preferred style. Connect your most frequently used internal tools via MCP to give the assistant the visibility it needs to provide high quality feedback on your specific project architecture.
Harsh’s take
Most developers treat AI code reviews as a novelty, but this update makes them a functional part of the engineering process. By forcing the AI to learn from your actual PR history, Cursor is finally moving away from generic suggestions toward context-aware feedback that actually respects your team's style guide. It is a necessary evolution for anyone tired of correcting the same trivial formatting errors in every single commit.
However, do not mistake this for a replacement for human oversight. You still need to understand the code being written, but you can now offload the tedious task of checking for common anti-patterns. If you are not using these learned rules, you are essentially paying for a tool that ignores your specific operational requirements.
