     - Add a Settings tab to the app UI that allows the user to configure a list of filter words.
     - When streaming output from MCP tool calls, any line containing one or more of these filter words
     - should be excluded from text-to-speech (TTS) synthesis.
     - This allows users to suppress noisy or irrelevant lines from being read aloud.
