Figuring out how to use streamable http mcp server

[benjaminbascary97]

Since the docs does not have any clear examples on how to use streameable mcp servers I want to see if anyone can give me any hints on using a mcp server:

My code:

fred_mcp = MCPServerStreamableHttp(params={"url": " https://22403a9df906.ngrok-free.app/mcp"}, name="fred-mcp-server")

with fred_mcp as fred_mcp_server:
    try:
        agent = Agent(
            name="Numeric Data Agent",
            instructions=PROMPT,
            tools=[pandas_tool],
            mcp_servers=[
                fred_mcp_server
            ],
            model=OpenAIResponsesModel(
                model=self.valves.openai_model,
                openai_client=client,
            ),
        )
    except Exception as e:
        print(f"Error connecting to fred_mcp: {e}")
        return f"Error connecting to fred_mcp: {e}"

result = Runner.run_streamed(
    starting_agent=agent,
    input=formatted_messages,
    max_turns=self.valves.max_turns,
)

This gives me the error:

TypeError: 'MCPServerStreamableHttp' object does not support the context manager protocol

But when using out of the context manager protocol, I get:

raise UserError("Server not initialized. Make sure you call `connect()` first.")
agents.exceptions.UserError: Server not initialized. Make sure you call `connect()` first.

With the code:

fred_mcp = MCPServerStreamableHttp(params={"url": " https://22403a9df906.ngrok-free.app/mcp"}, name="fred-mcp-server")

try:
    agent = Agent(
        name="Numeric Data Agent",
        instructions=PROMPT,
        tools=[pandas_tool],
        mcp_servers=[
            fred_mcp
        ],
        model=OpenAIResponsesModel(
            model=self.valves.openai_model,
            openai_client=client,
        ),
    )
except Exception as e:
    print(f"Error connecting to fred_mcp: {e}")
    return f"Error connecting to fred_mcp: {e}"

result = Runner.run_streamed(
    starting_agent=agent,
    input=formatted_messages,
    max_turns=self.valves.max_turns,
)

Can someone help me out?

Can you look at this example? https://github.com/openai/openai-agents-python/tree/main/examples/mcp/streamablehttp_example

TLDR you need async with fred_mcp , not with fred_mcp
