MCP-Gemini-Server provides a robust interface to Google's Gemini AI models through a collection of specialized tools. Built with TypeScript and the Model Context Protocol SDK, it enables AI assistants to leverage Gemini's capabilities including content generation, chat functionality, function calling, and file/cache management. The server implements both streaming and non-streaming content generation, supports stateful chat sessions with function execution, and offers comprehensive file and cache operations for optimizing performance. This implementation stands out by providing fine-grained control over generation parameters, safety settings, and tool configurations while handling error cases gracefully. It's particularly valuable for developers building AI applications that need direct access to Gemini's advanced features through a standardized protocol.
