This server has critical definition quality gaps. Tool descriptions are extremely terse (5-25 chars), far below the 194-char baseline for production tools. No input schemas are visible in the source code, parameters are documented only in docstring comments, not in structured JSON Schema. The tool interface is inferred from command-line argument parsing, not explicit MCP tool registration. No output schemas are documented. Error handling is minimal (generic JSON error responses). Security is weak: credentials passed as CLI arguments rather than server-side injection. The codebase shows no MCP server implementation, it's a standalone Python CLI that would need wrapping to function as an MCP server.

• Implement as a proper MCP server using the Python MCP SDK (mcp.run_server). Register tools with explicit JSON Schema input/output definitions, not CLI argument parsing.
• Expand all tool descriptions to 100-200 characters. Include WHAT the tool does, WHEN to use it, and any prerequisites. Example: 'Retrieve the current Lovelace dashboard configuration. Use this to inspect the dashboard layout before making updates. Requires Home Assistant admin access.'
• Document output schemas for every tool. Specify field names, types, and whether results are paginated. Example: get-config should return {config: object, success: boolean, error?: string}.
• Move HA_URL and HA_TOKEN to server-side configuration (environment variables read at startup, not passed as parameters). Inject credentials into WebSocket calls internally.
• Add parameter descriptions and type constraints. For save-config, document that 'config' must be a valid Lovelace dashboard JSON object; for hacs-download, specify that 'version' must match semantic versioning (e.g., '1.0.0').
