Blocks Control SDK

A unified Python interface to interact with popular coding agents.

Think of it like litellm, but for coding agents

Supported Agents

• Claude Code - Anthropic's Claude
• Gemini CLI - Google's Gemini
• Codex CLI - OpenAI's Codex
• Cursor CLI - Cursor's AI agent
• OpenCode - OpenCode CLI agent
• Kimi CLI - Kimi's AI agent

Installation

pip install blocks-control-sdk

You must also have the dependent agent packages installed to use a specific agent.

npm i -g @anthropic-ai/claude-code   # For Claude Code
npm i -g @google/gemini-cli           # For Gemini CLI
npm i -g @openai/codex-cli            # For Codex CLI
npm i -g @anthropic-ai/cursor-cli     # For Cursor CLI (if applicable)

Usage

Async Streaming

import asyncio
from blocks_control_sdk import ClaudeCode


async def main():
    agent = ClaudeCode()
    async for message in agent.stream("Write a python script to print 'Hello, World!'"):
        if isinstance(message, tuple):
            tool_name, args = message
            print(f"Tool call: {tool_name} with args {args}")
        else:
            print(message.content)

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

Sync with Callbacks

from blocks_control_sdk import Codex

agent = Codex()

def on_message(notification):
    print(notification.message.content)

agent.register_notification(agent.notifications.NOTIFY_MESSAGE_V2, on_message)

agent.query("Write a python script to print 'Hello, World!'")
