CodeArkt is a battery-included implementation of the CodeAct framework with support for the multi-agent architecture. Ship autonomous agents that can reason, write, execute & iterate over code. All from a single Python package.
- Multi-agent orchestration – coordinate hierarchies of specialist agents.
 - Secure Python sandbox – secure, ephemeral Docker execution environment for code actions.
 - First-class tool ecosystem – auto-discover & register MCP tools.
 - Drop-dead simple UI – launch an elegant Gradio chat or run the terminal client.
 - Production ready – typed codebase (
mypy --strict), CI, tests, Docker & Apache-2.0 license. 
Install the package:
pip install codearkt  # requires Python ≥ 3.12Run your MCP servers:
python -m academia_mcp --port 5056 # just an example MCP serverRun a server with a simple agent and connect it to your MCP servers:
import os
from codearkt.codeact import CodeActAgent
from codearkt.llm import LLM
from codearkt.server import run_server
# Use your own or remote MCP servers
mcp_config = {
    "mcpServers": {"academia": {"url": "http://0.0.0.0:5056/mcp", "transport": "streamable-http"}}
}
# Create an agent definition
api_key = os.getenv("OPENROUTER_API_KEY", "")
assert api_key, "Please provide OpenRouter API key!"
agent = CodeActAgent(
    name="manager",
    description="A simple agent",
    llm=LLM(model_name="deepseek/deepseek-chat-v3-0324", api_key=api_key),
    tool_names=["arxiv_download", "arxiv_search"],
)
# Run the server with MCP proxy and agentic endpoints
run_server(agent, mcp_config, port=5055)Now run a Python client:
from codearkt.client import query_agent
from codearkt.llm import ChatMessage
history = [ChatMessage(role="user", content="Find an abstract of the 2402.01030 paper")]
for event in query_agent(history, port=5055):
    if event.content:
        print(event.content, end="", flush=True)Within seconds, you will see agents collaborating, executing Python snippets, and streaming the results back to your console.
You can also use existing clients, Gradio and terminal:
uv run -m codearkt.terminal --port 5055
uv run -m codearkt.gradio --port 5055
| Area | Highlights | 
|---|---|
| Agents | Hierarchical manager / worker pattern, pluggable prompts, configurable iteration limits | 
| Tools | Automatic discovery via MCP registry, Python execution (python_interpreter) | 
| Execution | Sandboxed temp directory, timeout, streamed chunks, cleanup hooks | 
| Observability | AgentEventBus publishes JSON events – integrate with logs, websockets, or GUI. Opentelemetry is also supported. | 
| UI | Responsive Gradio Blocks chat with stop button, syntax-highlighted code & output panels | 
| Extensibility | Compose multiple CodeActAgent instances, add your own LLM backend, override prompts |
