How to better manage MCP resources in a FastAPI project?

[About-Gleaning]

Every time an agent is created, the MCP client has to be redefined. Is there a way to manage this centrally?

async def init_agent():
    client = MultiServerMCPClient({
        "mcp-server": {
            "url": "http://127.0.0.1:8080/sse",
            "transport": "sse"
        }
    })
    mcp_tools = await client.get_tools()

    llm = init_chat_model(
        model="deepseek-chat",
        temperature=0.0,
        max_retries=1,
    )

    graph_builder = StateGraph(SupplierState)
    ...
    agent = graph_builder.compile(name="channel_agent", checkpointer=checkpointer)
    return agent
