Cursor and Claude: How ACP Is Changing AI in the IDE
OpenIDE is adding basic support for ACP, an open protocol for connecting AI agents to IDEs. The idea is the same one that once worked for LSP: the agent and the editor talk over a shared standard, so developers choose their preferred environment and the tool they need independently. OpenIDE is preparing the feature for a beta. It will be part of the Pro version, but will also be available in the base build at launch.

Cursor, Claude Code and other AI coding agents each arrived with their own way of connecting to the editor, but ACP is becoming a new compatibility protocol: instead of a separate integration for every tool, the editor and the agent agree on a shared standard.
Which AI agents support the ACP protocol?
Claude Code, Codex, Cursor, Windsurf, Kilo Code, Qwen Code and other agents can write, fix and refactor code, and are gradually adding ACP support.
Why does the ACP protocol matter for IDEs?
Previously, each AI agent arrived with its own way of connecting to the editor. ACP lets them agree on a shared standard instead of requiring a separate integration for every tool.
What is the ACP protocol?
ACP is a new compatibility layer between IDEs and AI agents. Instead of a separate integration for each tool, the editor and the agent communicate over a common protocol.
Which IDEs are adding ACP support?
At the moment, JetBrains and Zed are adding ACP support and preparing it for beta testing.
