mcp-server-qdrant: A Qdrant MCP server

The Model Context Protocol (MCP) is an open protocol that enables seamless integration between LLM applications and external data sources and tools. Whether you’re building an AI-powered IDE, enhancing a chat interface, or creating custom AI workflows, MCP provides a standardized way to connect LLMs with the context they need.

This repository is an example of how to create a MCP server for Qdrant, a vector search engine.

Overview

A basic Model Context Protocol server for keeping and retrieving memories in the Qdrant vector search engine. It acts as a semantic memory layer on top of the Qdrant database.

Components

Tools

1. qdrant-store
   • Store some information in the Qdrant database
   • Input:
     • information (string): Information to store
     • metadata (JSON): Optional metadata to store
   • Returns: Confirmation message
2. qdrant-find
   • Retrieve relevant information from the Qdrant database
   • Input:
     • query (string): Query to use for searching
   • Returns: Information stored in the Qdrant database as separate messages

Installation in Claude Desktop

Using mcp (recommended)

When using mcp no specific installation is needed to directly run mcp-server-qdrant.

mcp install src/mcp_server_qdrant/server.py \
  -v QDRANT_URL="http://localhost:6333" \
  -v QDRANT_API_KEY="your_api_key" \
  -v COLLECTION_NAME="my_collection" \
  -v EMBEDDING_MODEL="sentence-transformers/all-MiniLM-L6-v2"

Installing via Smithery

To install Qdrant MCP Server for Claude Desktop automatically via Smithery:

npx @smithery/cli install mcp-server-qdrant --client claude

Manual configuration

To use this server with the Claude Desktop app, add the following configuration to the "mcpServers" section of your claude_desktop_config.json:

{
  "qdrant": {
    "command": "uvx",
    "args": ["mcp-server-qdrant"],
    "env": {
      "QDRANT_URL": "http://localhost:6333",
      "QDRANT_API_KEY": "your_api_key",
      "COLLECTION_NAME": "your_collection_name",
      "EMBEDDING_MODEL": "sentence-transformers/all-MiniLM-L6-v2"
    }
  }
}

For local Qdrant mode:

{
  "qdrant": {
    "command": "uvx",
    "args": ["mcp-server-qdrant"],
    "env": {
      "QDRANT_LOCAL_PATH": "/path/to/qdrant/database",
      "COLLECTION_NAME": "your_collection_name",
      "EMBEDDING_MODEL": "sentence-transformers/all-MiniLM-L6-v2"
    }
  }
}

This MCP server will automatically create a collection with the specified name if it doesn't exist.

By default, the server will use the sentence-transformers/all-MiniLM-L6-v2 embedding model to encode memories. For the time being, only FastEmbed models are supported.

Support for other tools

This MCP server can be used with any MCP-compatible client. For example, you can use it with Cursor, which provides built-in support for the Model Context Protocol.

Environment Variables

The configuration of the server is done using environment variables:

• QDRANT_URL: URL of the Qdrant server, e.g. http://localhost:6333
• QDRANT_API_KEY: API key for the Qdrant server (optional, depends on Qdrant server configuration)
• COLLECTION_NAME: Name of the collection to use (required)
• EMBEDDING_MODEL: Name of the embedding model to use (default: sentence-transformers/all-MiniLM-L6-v2)
• EMBEDDING_PROVIDER: Embedding provider to use (currently only "fastembed" is supported)
• QDRANT_LOCAL_PATH: Path to the local Qdrant database (alternative to QDRANT_URL)

Note: You cannot provide both QDRANT_URL and QDRANT_LOCAL_PATH at the same time.

Important

Command-line arguments are not supported anymore! Please use environment variables for all configuration.

Testing mcp-server-qdrant locally

The MCP inspector is a developer tool for testing and debugging MCP servers. It runs both a client UI (default port 5173) and an MCP proxy server (default port 3000). Open the client UI in your browser to use the inspector.

QDRANT_URL=":memory:" COLLECTION_NAME="test" \
mcp dev src/mcp_server_qdrant/server.py

Once started, open your browser to http://localhost:5173 to access the inspector interface.
