Cursor keeps calling mcp server even it's disconnected

I notice it will terminated after several times call, but why not stop calling once detect the server was disconnencted?

I have the same issue. I don’t know if it’s cursor’s bug or my mcp’s bug. Below is my mcp code

# server.py
from mcp.server.fastmcp import FastMCP

mcp = FastMCP(name="GreetingServer", port = 8090, host = "127.0.0.1")

@mcp.tool()
def greet(name: str) -> str:
    """Greet a user by name."""
    return f"Hello, {name}!"

if __name__ == "__main__":
    mcp.run(transport="streamable-http")

Hey, actually Cursor doesn’t initially know that the server is unavailable. It just sees that it’s enabled and tries to call it. When it fails after several attempts, it stops executing.
