An MCP server that bridges frontend applications to LLM APIs with WebSocket-based communication and session management
FrontendMCP is an extremely minimal MCP server with only 1 tool (get_current_date). The tool has a trivial implementation with no meaningful functionality or integration. The description is generic ('Returns the current date and time.'), and the input schema correctly declares no parameters but lacks any output schema documentation. The server appears to be a scaffolding/example implementation rather than a production tool. Definition quality is severely limited by the single, underdeveloped tool and complete absence of output schema documentation.
Returns the current date and time.
No output schema documented. Tool returns 'current date and time' but no field names, types, or format are specified. LLM cannot plan downstream operations or extract data reliably.
Generic, uninformative description (22 chars). Does not explain WHEN to use this tool, WHAT it returns (field names?), or any constraints. Fails baseline of 50-200 chars for LLM-optimized descriptions.
Input schema is correct (no params) but lacks accompanying context. No indication of purpose, constraints, or error conditions.
Only 1 tool total. Server does not address any substantial domain (e.g., frontend development, UI testing, code generation). Appears to be scaffolding or demo code.
