mcp-qdrant-embedding-search

MCP server that searches documents in Qdrant using embeddings from LMStudio.

Takes a text query, converts it to a vector via LMStudio's OpenAI-compatible API, and performs semantic search in Qdrant.

Prerequisites

• Node.js 18+
• LMStudio running with an embedding model loaded (default: text-embedding-qwen3-embedding-4b)
• Qdrant running with a collection containing your documents

Usage

With npx

  "mcpServers": {
    "qdrant-docs": {
      "command": "npx",
      "args": ["-y", "mcp-qdrant-embedding-search"],
      "env": {
        "QDRANT_URL": "http://localhost:6333",
        "QDRANT_COLLECTION": "my_docs",
        "LMSTUDIO_URL": "http://localhost:1234"
      }
    }
  }
