## About

Agent Client Protocol standardizes communication between coding agents and client applications such as code editors.

## Key Features

- Connect an agent implementation to compatible client interfaces.
- Exchange requests and notifications for interactive coding workflows.

## Setup or Requirements

Use the protocol documentation and a maintained SDK to implement or integrate a compatible agent or client.

## Compatibility

ACP standardizes agent-to-client communication through JSON-RPC. Choose an SDK and transport supported by both the agent and its editor client.

## Limitations

ACP addresses agent-to-client integration. It is distinct from A2A agent-to-agent communication and from an MCP server exposing tools.
