About qdrant-mcp-server

mhalder/qdrant-mcp-server

MCP server for semantic search using local Qdrant vector database and OpenAI embeddings

Supports multiple embedding providers (Ollama, OpenAI, Cohere, Voyage AI) with privacy-first local processing, plus specialized tools for code vectorization with AST-aware chunking and git history semantic search. Implements hybrid search combining semantic and keyword matching, contextual correlation across code+git repositories, and incremental indexing for efficient updates. Operates as both stdio and HTTP transport for Claude integration, with configurable custom prompts and support for secured Qdrant instances via API keys.
