AI Agent
Protocol for AgentOS implementations.
AgentOS is a production platform for deploying agents as web services.
It wraps agents, teams, and flows into a unified API server.
Implementations should:
* Provide FastAPI-based HTTP endpoints
* Support WebSocket connections for real-time communication
* Handle agent lifecycle management
* Provide health checks and monitoring endpoints
Example implementation (in praisonai wrapper):
class AgentOS:
def **init**(
self,
name: str = "PraisonAI App",
agents: List\[Agent] = None,
teams: List\[AgentTeam] = None,
flows: List\[AgentFlow] = None,
):
...
def serve(self, host: str = "0.0.0.0", port: int = 8000):
'''Start the FastAPI server.'''
...
def get\_app(self):
'''Get the FastAPI app instance for custom mounting.'''
...
```mermaid theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
%%{init: {'theme': 'base', 'themeVariables': { 'primaryColor': '#8B0000', 'primaryTextColor': '#fff', 'primaryBorderColor': '#710101', 'lineColor': '#189AB4', 'secondaryColor': '#189AB4', 'tertiaryColor': '#fff' }}}%%

## Methods
Start the AgentApp server.
Get the underlying web application instance.
## Notes
The protocol was renamed from `AgentAppProtocol` to `AgentOSProtocol` in v1.0.
`AgentAppProtocol` remains as a silent alias for backward compatibility.
