Agent Client Protocol integration for Deep Agents

Deep Agents ACP integration

This directory contains an Agent Client Protocol (ACP) connector that allows you to run a Python Deep Agent within a text editor that supports ACP such as Zed.

It includes an example coding agent that uses Anthropic's Claude models to write code with its built-in filesystem tools and shell, but you can also connect any Deep Agent with additional tools or different agent architectures!

Getting started

First, make sure you have Zed and uv installed.

Next, clone this repo:

git clone [e-mail]:langchain-ai/deepagents.git

Then, navigate into the newly created folder and run uv sync:

cd deepagents/libs/acp
uv sync --group examples

Rename the .env.example file to .env and add your Anthropic API key. You may also optionally set up tracing for your Deep Agent using LangSmith by populating the other env vars in the example file:

ANTHROPIC_API_KEY=""

# Set up LangSmith tracing for your Deep Agent (optional)

# LANGSMITH_TRACING=true
# LANGSMITH_API_KEY=""
# LANGSMITH_PROJECT="deepagents-acp"

Finally, add this to your Zed settings.json:

{
  "agent_servers": {
    "DeepAgents": {
      "type": "custom",
      "command": "/your/absolute/path/to/deepagents-acp/run_demo_agent.sh"
    }
  }
}

You must also make sure that the run_demo_agent.sh entrypoint file is executable - this should be the case by default, but if you see permissions issues, run:

chmod +x run_demo_agent.sh

Now, open Zed's Agents Panel (e.g. with CMD + Shift + ?). You should see an option to create a new Deep Agent thread:

And that's it! You can now use the Deep Agent in Zed to interact with your project.

If you need to upgrade your version of Deep Agents, pull the latest changes and re-sync:

git pull && uv sync --group examples

Or for specific packages:

uv lock --upgrade-package langchain_anthropic # for example

Launch a custom Deep Agent with ACP

uv add deepagents-acp

import asyncio

from acp import run_agent
from deepagents import create_deep_agent
from langgraph.checkpoint.memory import MemorySaver

from deepagents_acp.server import AgentServerACP


async def get_weather(city: str) -> str:
    """Get weather for a given city."""
    return f"It's always sunny in {city}!"


async def main() -> None:
    agent = create_deep_agent(
        tools=[get_weather],
        system_prompt="You are a helpful assistant",
        checkpointer=MemorySaver(),
    )
    server = AgentServerACP(agent)
    await run_agent(server)


if __name__ == "__main__":
    asyncio.run(main())

Launch with Toad

uv tool install -U batrachian-toad --python 3.14

toad acp "python path/to/your_server.py" .
# or
toad acp "uv run python path/to/your_server.py" .

Model Switching

The ACP adapter supports dynamic model switching using Session Config Options. This allows users to switch between different LLM models mid-session without losing conversation history.

Quick Example

from deepagents_acp.server import AgentServerACP, AgentSessionContext

# Define available models
models = [
    {"value": "anthropic:claude-opus-4-6", "name": "Claude Opus 4"},
    {"value": "anthropic:claude-sonnet-4", "name": "Claude Sonnet 4"},
    {"value": "openai:gpt-4-turbo", "name": "GPT-4 Turbo"},
]

# Create an agent factory that uses the model from context
def build_agent(context: AgentSessionContext):
    model = context.model

    # Pass model string directly - it handles provider:model-name format
    return create_deep_agent(
        model=model,
        checkpointer=checkpointer,
        backend=create_backend,
    )

# Pass models to the server
server = AgentServerACP(agent=build_agent, models=models)
