• 1

  Perform vector similarity search and retrieval from a Milvus database to support RAG (retrieval-augmented generation) workflows.

• 2

  Manage Milvus collections and schema (create, list, load, release) programmatically as part of application orchestration.

• 3

  Insert, query, and delete structured and unstructured data (including hybrid text + vector searches) in Milvus from within LLM-driven workflows.

Description

This open-source MCP server provides a bridge between LLM clients (like Claude Desktop and Cursor) and a Milvus vector database, enabling vector, text, and hybrid search as well as collection and data management. It supports both stdio (default) and HTTP Server-Sent Events (SSE) modes for flexible integration with desktop and web clients. The server exposes tools for listing/creating/loading collections, inserting and deleting data, full-text and vector similarity searches, and querying with filter expressions. Environment variables and CLI args let you configure connection, authentication, and runtime behavior.
