Context managers in MCP servers

MCP allows you to control the lifecycle management of your resources. Let’s have a look at some code:

async def load_settings() -> dict: """Load settings from a configuration file.""" # Simulate loading settings return {"setting1": "value1", "setting2": "value2"} @asynccontextmanager async def server_lifespan(server: Server) -> AsyncIterator[dict]: """Manage server startup and shutdown lifecycle.""" # Initialize resources on startup db = await Database.connect() settings = await load_settings() try: yield {"db": db, "settings": settings} finally: # Clean up on shutdown await db.disconnect() 

Here, we’ve done several things:

• Defined an asynchronous context manager, server_lifespan, that manages the lifecycle of the server
• Initialized...
