+Cursor now published their own acp client (finally :D): https://cursor.com/docs/cli/acp#ide-integrations

 Disclaimer: I am not affiliated with Cursor or Zed. This project is a personal experiment and should not be considered an official product of either company. I am a big fan of both products and wanted to combine what I like with both of them: An amazing editor and a great AI coding agent (and composer-1, holy this model flies xD).
 
 An [Agent Client Protocol (ACP)](https://github.com/agentclientprotocol/agent-client-protocol) adapter for [Cursor](https://cursor.com) Agent CLI, enabling Cursor's powerful AI coding assistant to be used within the [Zed](https://zed.dev) editor.
