Overview
Provides an enterprise-grade Model Context Protocol (MCP) server that integrates with an R2R (Retrieval & RAG) backend, offering tools for hybrid search, RAG queries, multi-turn agent conversations, collection management, document upload, and automated workflows, optimized for client applications like Cursor or Claude Desktop.

Security Notes
The server employs good security practices, including loading API keys from environment variables, implementing rate limiting, and using an ErrorHandlingMiddleware to prevent exposure of raw internal exceptions. Input validation is also demonstrated as a best practice. The overall security relies on proper configuration and the underlying R2R instance's security.
