Specifying capabilities w/ FastMCP Server

Question

I noticed that the FastMCP server does not have the options to manually specify the capabilities of the server, however it is possible to do so with the low-level server.

My current workaround to advertise the capabilities is like so:

mcp = FastMCP("test-server")

# Manually set notification options
lowlevel_server: Server = mcp._mcp_server
lowlevel_server.notification_options.resources_changed = True
lowlevel_server.notification_options.tools_changed = True

# Now, we override the mcp.run()
async def main():
    async with stdio_server() as (r, w):
        init_opts = lowlevel_server.create_initialization_options(
            lowlevel_server.notification_options,
            {}
        )
        await lowlevel_server.run(r, w, init_opts)

if __name__ == "__main__":
    anyio.run(main)

Is there any other way to specify the capabilities of the FastMCP server? Is there a reason not to?

Thanks!

Empieza leyendo el punto de entrada de FastMCP y los métodos de bajo nivel de Server mostrados en el informe: notification_options, create_initialization_options y run. Determina cómo la inicialización de FastMCP expone actualmente las capabilities y define «done» como permitir especificar esas capabilities sin sobrescribir mcp.run().
