RagDocs MCP Server

A Model Context Protocol (MCP) server that provides RAG (Retrieval-Augmented Generation) capabilities using Qdrant vector database and Ollama/OpenAI embeddings. This server enables semantic search and management of documentation through vector similarity.

Features

• Add documentation with metadata

• Semantic search through documents

• List and organize documentation

• Delete documents

• Support for both Ollama (free) and OpenAI (paid) embeddings

• Automatic text chunking and embedding generation

• Vector storage with Qdrant
