Cursor Brings AI-Powered Coding to JetBrains IDEs Through Agent Client Protocol

Summary

Cursor has expanded its AI-powered coding capabilities to JetBrains IDEs, including IntelliJ IDEA, PyCharm, and WebStorm, through the Agent Client Protocol (ACP). This integration allows developers who prefer JetBrains' development environments to access Cursor's agent-driven coding features without leaving their preferred IDE. The move represents a significant expansion of Cursor's reach into the developer tools market, particularly among Java and enterprise developers who traditionally rely on JetBrains products.

The integration leverages the Agent Client Protocol to combine Cursor's AI capabilities with JetBrains' deep code intelligence and tooling. Developers can now access frontier models from OpenAI, Anthropic, Google, and Cursor directly within their JetBrains IDE, with each model optimized through Cursor's custom-built agent harness. The system includes secure codebase indexing and semantic search capabilities designed to understand large enterprise codebases.

The Cursor ACP is available free for all users on paid Cursor plans and can be installed directly from the ACP Registry within JetBrains IDEs. According to Aleksey Stukalov, Head of IDEs Division at JetBrains, the collaboration allows developers to maintain control of their environment while gaining access to Cursor's AI assistance. Both companies indicate this is just the beginning, with plans for deeper integrations in the future.
