Chatty MCP exposes only a single tool 'speak' with minimal definition quality. The tool lacks a proper input schema (only a free-form content string), has a description under 20 characters that fails to explain when/why to use it, and provides no output schema documentation. Parameter descriptions are missing type information and constraints. The server appears to be a simple voice synthesis wrapper with no error handling, recovery guidance, or composition support. This is a proof-of-concept rather than a production-grade tool.

• Expand tool description to 50-150 characters: e.g., 'Speak content aloud to the user. Use this to provide audible feedback, confirm actions, or narrate explanations. Returns success status and duration played.'
• Add format and length constraints to 'content' parameter: e.g., 'Plain text or markdown content to speak aloud. Max 5000 characters. Avoid code blocks, URLs, and special symbols.'
• Document output schema explicitly: e.g., '{ "status": "success|failed", "duration_ms": <number>, "characters_spoken": <number> }'
• Add error handling examples: e.g., 'If no audio device is available, returns { "status": "failed", "error": "No audio device detected. Check system sound settings." }'
• Rename tool to 'speak_to_user' or 'narrate_content' for clarity and verb-noun alignment.
• Specify voice customization options (if supported): e.g., 'Accepts optional rate (0.5 - 2.0) and voice_id parameters for speech rate and voice style.'
• Include interaction guidance: e.g., 'Ideal for confirming long operations, explaining errors, or summarizing results. Use sparingly to avoid overwhelming the user with audio.'
