BEYOND MCP has clear naming conventions (verb_noun pattern) and comprehensive parameter schemas with type definitions. However, descriptions are inconsistent in depth and quality. Most tool descriptions are adequate (50-150 chars) but lack actionable context for LLM selection. Parameter descriptions are present but often minimal. Error handling is structured via _handle_errors decorator, but recovery guidance is limited. Output schemas are implicit (JSON responses) rather than explicitly documented. The server demonstrates solid foundational quality but falls short of production-grade polish in description depth and error messaging.

• Add explicit output schema documentation to each tool. Example: 'Returns {ok: true, address: string, values: array, packet_hex: string}' for preview_osc. This enables LLMs to plan downstream operations.
• Enhance descriptions with WHEN/WHY context. E.g., 'Use send_osc_raw for OSC addresses not yet wrapped by named tools (e.g., custom vendor extensions). For common operations like brightness or blackout, prefer named tools for safety checks.'
• Improve error messages with recovery guidance. Replace 'Invalid JSON input: ...' with 'Invalid JSON in values_json. Ensure it is a valid JSON array. Example: [120, "text", 0.5]'.
• Document the confirm_destructive safety model in tool descriptions. Add: 'When BEYOND_CONFIRM_DESTRUCTIVE is enabled, set confirm=true to acknowledge this operation disables laser output.'
• Add parameter format examples to JSON input descriptions. E.g., 'messages_json: JSON array of [address, values] pairs. Example: [[\'/beyond/general/SetBpm\', [120]], [\'/beyond/general/BlackOut\', []]]'.
