Security Notes
The `FastMCPWithCORS` class hardcodes `allow_origins=["*"]` for CORS middleware in its `streamable_http_app` and `sse_app` methods. This creates a security vulnerability by allowing cross-origin requests from any domain, even if a more restrictive `cors_allow_origins` is set in the application's `Settings`. While this might be acceptable for a locally run MCP server, it is a significant network security risk if the server is deployed to a publicly accessible IP address without additional security measures.
