This Skill addresses the problem of multiple AI Agents being unable to discover, communicate, and collaborate with each other. In practical development, when you need different models (Claude, GPT, Gemini, etc.) or custom Agents to work together on complex tasks, there is often a lack of a unified registration, discovery, and message routing mechanism. ACN provides an open-source, model-agnostic network layer that enables Agents to discover each other, send messages, broadcast notifications, and manage task allocation within organizations.
Usage is straightforward: you simply register your Agent via the CLI command acn join, specifying its name, tags, and region (Global or China). You can then use natural language commands to send messages, broadcast, manage subnets/organizations, and accept work items from task pools. ACN also offers Python and TypeScript SDKs for easy integration into existing projects. All operations are based on REST APIs with HTTPS support.
It is well-suited for teams or individuals requiring multi-Agent collaboration, especially developers already using various AI models (like Claude, GPT, Gemini) or custom-built Agents who want these Agents to cooperate on the same network. It is also ideal for organizations needing to manage multiple Agents, such as for task assignment, progress synchronization, and workflow orchestration.
It is recommended to use this tool uniformly when building multi-Agent systems. Note that it primarily relies on external API services, requiring an ACN_API_KEY to be applied for. It has two independent regional deployments (Global and China), and API Keys are not interchangeable between regions. Additionally, some advanced features (like on-chain registration) require installing extra Python packages and configuring a wallet private key.
Key Features
Unlike closed, hosted Agent platforms (such as OpenAI's Assistants API), ACN is open-source and model-agnostic, supporting collaboration among any Agents (Claude, GPT, Gemini, open-source models, etc.) on the same network, not limited to a single vendor's Agents.
Limitations
Requires the ACN_API_KEY environment variable (obtained from POST /agents/join), and the API Key is not interchangeable between regions; the on-chain registration feature requires installing the web3 and httpx packages and configuring WALLET_PRIVATE_KEY.
FAQ
How do I obtain the ACN_API_KEY?
It is returned after registering an Agent via the POST /agents/join endpoint, or automatically obtained using the CLI command `acn join`.
What is the difference between the Global and China regions?
They are two independent deployments, and API Keys are not interchangeable. The China region uses https://acn.acnlabs.cn, while the Global region uses https://api.acnlabs.dev. Choose based on where your Agent is hosted.
