A collection of MCP servers for Gemini Spark integration, including hello-world demo and Omi bridge proxy. Implements OAuth 2.1 + Dynamic Client Registration for Spark-compatible MCP servers.
Single tool 'echo' has a clear, concise description (89 chars) and properly typed input schema with parameter description. Naming is verb-based and appropriate. However, the tool is trivial (read-only confirmation only), output schema is not documented, and there is no error handling guidance. The server lacks production-grade tool depth, one echo tool does not constitute a meaningful agent toolkit. Descriptions meet baseline (10-1024 chars), but lack the LLM-optimization detail (50-200 chars) expected of A-grade tools.
Echo a message back to the caller. Confirms the MCP connection and OAuth authentication are working end to end.
Output schema not documented. Tool returns unstructured response; LLM cannot plan downstream calls or extract structured data.
No error handling guidance. Tool description does not explain failure modes, recovery steps, or when to retry.
Trivial tool surface. Single echo tool is a connectivity test, not a functional agent toolkit. No real business logic or domain tools.
Parameter description is minimal (18 chars). Should explain context, constraints, and examples of valid input.
