Specifying capabilities w/ FastMCP Server #1126
Description
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!
