uAgents is a fast, lightweight framework developed by Fetch.ai for creating decentralized autonomous AI agents in Python. Through simple and expressive decorators, it enables developers to define agents that perform tasks on a schedule or react to various events.
Key capabilities:
- Easy creation and management: You can create and implement any type of agent in code.
- Automatic network connection: When an agent starts, it automatically registers with Almanac (a smart contract deployed on the Fetch.ai blockchain) and joins the growing uAgents network.
- Secure: uAgent messages and wallets are cryptographically protected, ensuring identities and assets are safeguarded.
- Observable: Agents registered with Agentverse automatically report start/stop, message (send/receive), and error telemetry events to the Agentverse dashboard, controllable via the report_events switch.
Usage: Installation supports Python 3.10 to 3.13. When creating an agent, you can pass a seed parameter (for example, obtained from an environment variable) to set a fixed address; otherwise, the agent's private key is stored locally in the private_keys.json file under its name. If no name is specified (such as alice = Agent()), each run of the agent generates a new address. Afterward, you can give the agent a simple task, such as a greeting, and view the result in the terminal.
Use cases: Suitable for developers who need to build decentralized AI agents that can run autonomously and communicate with each other. The official documentation provides complete setup instructions and advanced features, and tutorials include creating agents, agent communication, and ASI:One-compatible agents. Key concepts cover addresses, storage, synchronous communication, and agent broadcasting. The uAgent-Examples repository contains various agent examples and more complex integrations, and is the official place for internal and community open-source applications. The python folder contains detailed information about the Python uAgents library, and the uagents-core folder contains the core definitions and functionality for building integrations that can interact with the Fetch.ai ecosystem and agent marketplace.
