Agent Client Protocol (ACP)

Agent Client Protocol is an open protocol for standardizing communication between code editors and AI coding agents. It defines how an interactive editor can connect to an agent that reads, edits, and reasons about source code. The project is meant to reduce fragmentation between IDEs, terminal tools, and autonomous coding systems by creating a shared communication layer. Its goal is to let any compatible editor work with any compatible coding agent without every integration being custom-built. The repository includes protocol materials and SDK-related ecosystem work for clients and agents. It is useful for editor makers, agent builders, and tool developers who want cleaner interoperability in AI-assisted software development.
