Protocol
Agent Client Protocol
ACP DraftStewarded by Zed Industries
01 / What it is
A JSON-RPC protocol between a code editor and a coding agent so any compliant agent can run inside any compliant editor, with the editor owning the UI and file access.
Editor-side: how an IDE drives an agent. AG-UI is the web front-end equivalent.
