The SDK to build event-driven, distributed AI agents

The SDK to build event-driven, distributed AI agents.

Calfkit lets you compose agents with independent services—chat, tools, routing—that communicate asynchronously. Add agent capabilities without coordination. Scale each component independently. Stream agent outputs to any downstream system. Build employees that integrate.

Building agents like traditional web applications, with tight coupling and synchronous API calls, creates the same scalability problems that plagued early microservices. Agents and workflows connected through APIs and RPC are plagued by:

Event-driven architectures provide the solution. Instead of direct API calls between components, agents and tools interact through asynchronous streams. Each component runs independently, scales horizontally, and outputs can flow anywhere: CRMs, data warehouses, analytics platforms, other agents, or even more tools.

Calfkit is a Python SDK that builds event-driven agents out-the-box. You get all the benefits of a asynchronous, distributed system (loose coupling, horizontal scalability, durability) without the complexity of managing event-driven infrastructure and orchestration yourself.

Calfkit uses Kafka as the event broker. Run the following command to clone the calfkit-broker repo and start a local Kafka broker container:

Once the broker is ready, open a new terminal tab to continue with the quickstart.

Define and deploy a tool as an independent service.

Deploy the agent router that orchestrates chat, tools, and conversation-level memory.
