Crate adk_acp 

adk-acp — Agent Client Protocol integration for ADK-Rust

Connect ADK agents to external ACP agents (Claude Code, Codex, etc.) and optionally expose ADK agents as ACP-compatible agents for IDE connections.

Quick Start

use adk_acp::AcpAgentTool;
use adk_agent::LlmAgentBuilder;
use std::sync::Arc;

// Wrap Claude Code as a tool your agent can delegate to
let claude = AcpAgentTool::new("claude-code")
    .description("Delegate complex coding tasks to Claude Code");

let agent = LlmAgentBuilder::new("orchestrator")
    .instruction("Use claude-code for complex refactoring tasks.")
    .model(model)
    .tool(Arc::new(claude))
    .build()?;

What is ACP?

The Agent Client Protocol standardizes communication between code editors (IDEs, CLIs) and coding agents. It enables:

• Tool use: Agents can request permission to use tools
• Streaming responses: Real-time content delivery
• Session management: Multi-turn conversations with context
• Proxy chains: Middleware that intercepts/transforms messages

Features

• default: Client-side only (connect to ACP agents)
• server: Expose ADK agents as ACP-compatible agents
