Interfaces

Expose Kern agents through various communication protocols and platforms

Interfaces enable exposing Kern agents, teams, and workflows through various communication protocols and platforms. Each interface provides a standardized way to connect Kern agents to external systems, messaging platforms, and frontend applications.

Available Interfaces

desktop

AG-UI

Connect agents to frontend applications using the Agent-User Interaction Protocol

slack

Slack

Deploy agents as Slack applications for team collaboration

Serve agents via WhatsApp for direct messaging interactions

Deploy agents as Telegram bots for direct and group chat conversations

code

A2A

Expose agents via the Agent-to-Agent Protocol for inter-agent communication

How Interfaces Work

Interfaces are FastAPI routers that mount protocol-specific endpoints on an AgentOS instance. Each interface:

Wraps Kern agents, teams, or workflows into protocol-compatible endpoints
Handles authentication and request validation for the target platform
Manages session tracking and context preservation
Streams responses back to clients in the appropriate format

Using Interfaces

Interfaces are added to an AgentOS instance through the interfaces parameter:

1from kern.os import AgentOS
2from kern.os.interfaces.slack import Slack
3
4agent_os = AgentOS(
5    agents=[my_agent],
6    interfaces=[Slack(agent=my_agent)],
7)
8app = agent_os.get_app()

Multiple interfaces can be added to a single AgentOS instance, allowing the same agents to be exposed through different protocols simultaneously.
