Run your existing OpenAI Agents SDK code through Motus with automatic tracing and cloud deployment. Import from motus.openai_agents instead of agents. Your agent definitions, tool functions, and run logic stay exactly the same.

​
Installation

uv sync --extra openai-agents

​
Basic usage

Replace your agents import with motus.openai_agents: 
from motus.openai_agents import Agent, Runner

agent = Agent(name="assistant", instructions="You are helpful.")
result = await Runner.run(agent, "Hello!")
print(result.final_output)
The Runner wraps every call with tracing and model interception. You do not need to change your agent definitions, tool functions, or run logic.

​
What Motus adds

​
Tracing

Every agent turn, tool call, and model generation is captured by TraceManager. The MotusTracingProcessor replaces the SDK’s default BackendSpanExporter (which posts traces to api.openai.com) on import. Traces flow into the Motus trace viewer, Jaeger export, and analytics pipeline. Tracing is auto-registered when you import motus.openai_agents. You can also register it explicitly: 
from motus.openai_agents import register_tracing

register_tracing()
To export traces manually before process exit: 
from motus.openai_agents import get_tracer

tracer = get_tracer()
if tracer:
    tracer.export_trace()
Traces are auto-exported on process exit when TraceManager.config.export_enabled is True. Manual export is only needed when you want to flush mid-run.

​
Model proxy

When deployed to Motus cloud, the platform automatically routes OpenAI Responses API calls through the model proxy. No OPENAI_API_KEY is needed in the deployed environment - the proxy handles authentication, rate limiting, and cost tracking transparently.

​
Model wrapping

MotusOpenAIProvider and MotusMultiProvider sit in the model call path as transparent pass-throughs. Future releases will add hooks for caching, routing, and cost control at this layer.

​
Tool wrapping

Tool invocations are intercepted before execution. Each function_tool call produces a traced span with input arguments and output. Future releases will add tool-level optimization and caching.

​
Runner methods

Runner exposes the same three methods as the SDK’s original Runner: 
result = await Runner.run(agent, "Hello!")
Each method registers tracing, wraps tools, and injects a MotusOpenAIProvider into the RunConfig before delegating to the original SDK runner.

​
Run configuration

You can pass a custom RunConfig. Motus upgrades the default OpenAIProvider or MultiProvider to their Motus counterparts. If you supply your own custom provider, Motus preserves it: 
from motus.openai_agents import Runner, RunConfig, MotusOpenAIProvider

config = RunConfig(model_provider=MotusOpenAIProvider())
result = await Runner.run(agent, "Hello!", run_config=config)

​
Deployment

​
Local serving

motus serve start myapp:agent --port 8000
Where agent is an OpenAI Agent instance. No adapter import is needed.

​
Cloud deployment

cd my_project
motus deploy --name my-agent tools:agent
When deploying to Motus cloud, include requirements.txt with openai-agents>=0.13.4 (the SDK is not in the base image). No API key secrets are needed. The platform routes Responses API calls through the model proxy. Session state (conversation history) is persisted in DynamoDB and survives backend restarts, failovers, and scaling events.
Guardrail tripwire exceptions are caught and returned as refusal messages. Structured output (Pydantic models, dataclasses) is serialized to JSON automatically.

​
What works

All OpenAI Agents SDK features are supported:
  • function_tool definitions
  • Agent with instructions, tools, and handoffs
  • Runner.run(), Runner.run_sync(), Runner.run_streamed()
  • Handoffs between agents
  • Guardrails (input and output)
  • Custom tools and MCP tools
  • Multi-provider routing (OpenAI, LiteLLM)

​
Motus-specific exports

In addition to re-exporting the full agents package, motus.openai_agents provides these additional names:
ExportDescription
MotusModelBase model wrapper
MotusResponsesModelResponses API model wrapper
MotusChatCompletionsModelChat Completions API model wrapper
MotusLitellmModelLiteLLM model wrapper
MotusOpenAIProviderProvider that returns Motus model wrappers
MotusMultiProviderMulti-provider with Motus interception
MotusLitellmProviderLiteLLM provider with Motus interception
MotusTracingProcessorBridges OpenAI Agents SDK spans into TraceManager
register_tracing()Registers the tracing processor (called automatically on import)
get_tracer()Returns the TraceManager instance
from motus.openai_agents import X re-exports everything from the agents package. Motus overrides Runner, OpenAIProvider, MultiProvider, and model classes with its own wrappers at import time.

​
Traced span types

The integration produces span types in TraceManager via the MotusTracingProcessor, which bridges OpenAI Agents SDK span events:
Span typeDescription
agentAgent invocation spans. Contains agent name, instructions, and handoff information.
model_callLLM generation spans. Contains model name, token usage, and request/response data.
tool_callTool execution spans. Contains tool name, input arguments, output, and error status.
guardrailGuardrail evaluation spans. Contains guardrail name and pass/fail result.
