qdrant-llamaindex-mcp-server 0.1.1

MCP server for reading LlamaIndex documents stored in Qdrant vector database

qdrant-llamaindex-mcp-server: LlamaIndex-Compatible 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 a fork of qdrant/mcp-server-qdrant specifically designed to work with documents stored by LlamaIndex in Qdrant vector databases.

⚠️ Important Differences from Official Server

This fork has breaking changes compared to the official qdrant/mcp-server-qdrant:

• 🔧 Many More Tools: Provides 10+ tools vs. the official server's basic find/store tools
• 🎯 Dynamic Collection Selection: Collection names are specified at runtime by MCP clients, not hardcoded in configuration
• 🤖 Dynamic Embedding Model Detection: Automatically detects and loads the correct embedding model for each collection
• 📚 LlamaIndex Compatibility: Adapts to different content field names and metadata structures used by LlamaIndex
• 🔒 Enhanced Security: Built-in embedding model whitelist to prevent accidental loading of large models

These changes make configurations incompatible with the official server. You cannot simply swap this server for the official one without updating your configuration and workflow.

Overview

A comprehensive Model Context Protocol server for working with documents stored by LlamaIndex in Qdrant vector databases. Unlike the original server which provides basic functionality with a fixed document structure, this version offers extensive tooling and automatically adapts to different payload formats used by LlamaIndex.

Key Features

• LlamaIndex Compatibility: Automatically detects and adapts to different content field names (text, document, _node_content, etc.)
• Dynamic Embedding Model Detection: Automatically detects and uses the correct embedding model for each collection based on its vector configuration
• Embedding Model Whitelist: Built-in safety mechanism to prevent accidentally loading large models
• Flexible Metadata Handling: Works with both flat and nested metadata structures
• Read-Only Access: Designed specifically for querying existing LlamaIndex-indexed data
• Smart Content Detection: Automatically identifies the most likely content field when standard names aren't found

Environment Variables

The configuration of the server is done using environment variables:

Name	Description	Default Value
QDRANT_URL	URL of the Qdrant server	None
QDRANT_API_KEY	API key for the Qdrant server	None
COLLECTION_NAME	Deprecated: Collection names are now specified dynamically by MCP clients at runtime	None
QDRANT_READ_ONLY	Enable read-only mode (disables write tools for safety)	false
QDRANT_LOCAL_PATH	Path to the local Qdrant database (alternative to QDRANT_URL)	None
EMBEDDING_PROVIDER	Embedding provider to use (currently only "fastembed" is supported)	fastembed
EMBEDDING_MODEL	Default embedding model (used as fallback when auto-detection fails or model not in whitelist)	sentence-transformers/all-MiniLM-L6-v2
EMBEDDING_ALLOWED_MODELS	JSON array of allowed embedding models for dynamic loading	["sentence-transformers/all-MiniLM-L6-v2", "BAAI/bge-small-en-v1.5", "snowflake/snowflake-arctic-embed-xs", "jinaai/jina-embeddings-v2-small-en"]
TOOL_FIND_DESCRIPTION	Custom description for the find tool	See default in settings.py

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.

FastMCP Environment Variables

Since mcp-server-qdrant is based on FastMCP, it also supports all the FastMCP environment variables. The most important ones are listed below:

Environment Variable	Description	Default Value
FASTMCP_DEBUG	Enable debug mode	false
FASTMCP_LOG_LEVEL	Set logging level (DEBUG, INFO, WARNING, ERROR, CRITICAL)	INFO

FASTMCP_WARN_ON_DUPLICATE_PROMPTS	Show warnings for duplicate prompts	true
FASTMCP_DEPENDENCIES	List of dependencies to install in the server environment	[]

Dynamic Embedding Model Detection

This server automatically detects which embedding model was used for each collection and uses the appropriate model for queries. This is especially useful when you have multiple collections created with different embedding models.

How It Works

1. Collection Creation: When LlamaIndex creates a collection, the full model name is stored as the vector name (e.g., "BAAI/bge-small-en-v1.5")
2. Query Time: When searching a collection, the server:
   • Inspects the collection's vector configuration
   • Extracts the model name from the vector name
   • Loads the appropriate embedding model (with caching for performance)
   • Uses that model to embed the query

Embedding Model Whitelist

For security and resource management, the server includes a built-in whitelist of allowed embedding models. By default, only small, efficient models are permitted:

• sentence-transformers/all-MiniLM-L6-v2 (384 dims, ~90MB)
• BAAI/bge-small-en-v1.5 (384 dims, ~67MB)
• snowflake/snowflake-arctic-embed-xs (384 dims, ~90MB)
• jinaai/jina-embeddings-v2-small-en (512 dims, ~120MB)

Customizing the Whitelist

Using Environment Variables

# Allow only specific models
export EMBEDDING_ALLOWED_MODELS='["sentence-transformers/all-MiniLM-L6-v2", "BAAI/bge-small-en-v1.5"]'

# Allow all models (removes safety protection)
export EMBEDDING_ALLOWED_MODELS='null'

In Claude Desktop Config

{
  "mcpServers": {
    "qdrant": {
      "command": "uvx",
      "args": ["qdrant-llamaindex-mcp-server"],
      "env": {
        "QDRANT_URL": "http://localhost:6333",
        "COLLECTION_NAME": "your-collection",
        "EMBEDDING_ALLOWED_MODELS": "[\"sentence-transformers/all-MiniLM-L6-v2\", \"BAAI/bge-small-en-v1.5\"]"
      }
    }
  }
}

Behavior with Blocked Models

When the server encounters a collection using a model not in the whitelist:

• ⚠️ Logs a warning message
• 🔄 Falls back to the default configured model (EMBEDDING_MODEL)
• ✅ Continues operating normally

This ensures your system remains stable while preventing accidental downloads of large models.

Installation

Using uvx (Recommended)

From PyPI

QDRANT_URL="http://localhost:6333" \
uvx qdrant-llamaindex-mcp-server

From GitHub Repository (Development)

QDRANT_URL="http://localhost:6333" \
uvx --from git+https://github.com/azhang/qdrant-llamaindex-mcp-server.git qdrant-llamaindex-mcp-server

From Local Directory (Development)

# Clone and run locally
git clone https://github.com/azhang/qdrant-llamaindex-mcp-server.git
cd qdrant-llamaindex-mcp-server

QDRANT_URL="http://localhost:6333" \
uvx --from . qdrant-llamaindex-mcp-server

Transport Protocols

The server supports different transport protocols that can be specified using the --transport flag:

QDRANT_URL="http://localhost:6333" \
uvx qdrant-llamaindex-mcp-server --transport sse

Supported transport protocols:

• stdio (default): Standard input/output transport, might only be used by local MCP clients
• sse: Server-Sent Events transport, perfect for remote clients
• streamable-http: Streamable HTTP transport, perfect for remote clients, more recent than SSE

The default transport is stdio if not specified.

When SSE transport is used, the server will listen on the specified port and wait for incoming connections. The default port is 8000, however it can be changed using the FASTMCP_PORT environment variable.

QDRANT_URL="http://localhost:6333" \
FASTMCP_PORT=1234 \
uvx qdrant-llamaindex-mcp-server --transport sse

Using Docker

A Dockerfile is available for building and running the MCP server:

# Build the container
docker build -t mcp-server-qdrant .

# Run the container
docker run -p 8000:8000 \
  -e FASTMCP_HOST="0.0.0.0" \
  -e QDRANT_URL="http://your-qdrant-server:6333" \
  -e QDRANT_API_KEY="your-api-key" \
  -e COLLECTION_NAME="your-collection" \
  mcp-server-qdrant

[!TIP] Please note that we set FASTMCP_HOST="0.0.0.0" to make the server listen on all network interfaces. This is necessary when running the server in a Docker container.

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 of Claude Desktop

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": ["qdrant-llamaindex-mcp-server"],
    "env": {
      "QDRANT_URL": "https://xyz-example.eu-central.aws.cloud.qdrant.io:6333",
      "QDRANT_API_KEY": "your_api_key",
      "QDRANT_READ_ONLY": "true"
    }
  }
}

For local Qdrant mode:

{
  "qdrant": {
    "command": "uvx",
    "args": ["qdrant-llamaindex-mcp-server"],
    "env": {
      "QDRANT_LOCAL_PATH": "/path/to/qdrant/database",
      "QDRANT_READ_ONLY": "true"
    }
  }
}

[!NOTE] Collection Names: Collection names are now specified dynamically when using the tools (e.g., when calling qdrant-find, you specify which collection to search). This provides more flexibility than the previous approach of hardcoding a single collection name.

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 and VS Code, which provide built-in support for the Model Context Protocol.

Using with Cursor/Windsurf

You can configure this MCP server to work as a code search tool for Cursor or Windsurf by customizing the tool descriptions:

QDRANT_URL="http://localhost:6333" \
TOOL_STORE_DESCRIPTION="Store reusable code snippets for later retrieval. \
The 'information' parameter should contain a natural language description of what the code does, \
while the actual code should be included in the 'metadata' parameter as a 'code' property. \
The value of 'metadata' is a Python dictionary with strings as keys. \
Use this whenever you generate some code snippet." \
TOOL_FIND_DESCRIPTION="Search for relevant code snippets based on natural language descriptions. \
The 'query' parameter should describe what you're looking for, \
and the tool will return the most relevant code snippets. \
Use this when you need to find existing code snippets for reuse or reference." \
uvx qdrant-llamaindex-mcp-server --transport sse # Enable SSE transport

In Cursor/Windsurf, you can then configure the MCP server in your settings by pointing to this running server using SSE transport protocol. The description on how to add an MCP server to Cursor can be found in the Cursor documentation. If you are running Cursor/Windsurf locally, you can use the following URL:

http://localhost:8000/sse

[!TIP] We suggest SSE transport as a preferred way to connect Cursor/Windsurf to the MCP server, as it can support remote connections. That makes it easy to share the server with your team or use it in a cloud environment.

This configuration transforms the Qdrant MCP server into a specialized code search tool that can:

1. Store code snippets, documentation, and implementation details
2. Retrieve relevant code examples based on semantic search
3. Help developers find specific implementations or usage patterns

You can populate the database by storing natural language descriptions of code snippets (in the information parameter) along with the actual code (in the metadata.code property), and then search for them using natural language queries that describe what you're looking for.

[!NOTE] The tool descriptions provided above are examples and may need to be customized for your specific use case. Consider adjusting the descriptions to better match your team's workflow and the specific types of code snippets you want to store and retrieve.

If you have successfully installed the mcp-server-qdrant, but still can't get it to work with Cursor, please consider creating the Cursor rules so the MCP tools are always used when the agent produces a new code snippet. You can restrict the rules to only work for certain file types, to avoid using the MCP server for the documentation or other types of content.

Using with Claude Code

You can enhance Claude Code's capabilities by connecting it to this MCP server, enabling semantic search over your existing codebase.

Setting up qdrant-llamaindex-mcp-server

1. Add the MCP server to Claude Code:

   # Add qdrant-llamaindex-mcp-server configured for code search
   claude mcp add code-search \
   -e QDRANT_URL="http://localhost:6333" \
   -e QDRANT_READ_ONLY="true" \
   -e TOOL_STORE_DESCRIPTION="Store code snippets with descriptions. The 'information' parameter should contain a natural language description of what the code does, while the actual code should be included in the 'metadata' parameter as a 'code' property." \
   -e TOOL_FIND_DESCRIPTION="Search for relevant code snippets using natural language. The 'query' parameter should describe the functionality you're looking for." \
   -- uvx qdrant-llamaindex-mcp-server
   

2. Verify the server was added:

   claude mcp list
   

Using Semantic Code Search in Claude Code

Tool descriptions, specified in TOOL_STORE_DESCRIPTION and TOOL_FIND_DESCRIPTION, guide Claude Code on how to use the MCP server. The ones provided above are examples and may need to be customized for your specific use case. However, Claude Code should be already able to:

1. Use the qdrant-store tool to store code snippets with descriptions.
2. Use the qdrant-find tool to search for relevant code snippets using natural language.

Run MCP server in Development Mode

The MCP server can be run in development mode using the mcp dev command. This will start the server and open the MCP inspector in your browser.

fastmcp dev src/mcp_server_qdrant/server.py

          "COLLECTION_NAME": "${input:collectionName}"
        }
      }
    }
  }
}

Or if you prefer using Docker, add this configuration instead:

{
  "mcp": {
    "inputs": [
      {
        "type": "promptString",
        "id": "qdrantUrl",

          "COLLECTION_NAME": "${input:collectionName}"
        }
      }
    }
  }
}

Alternatively, you can create a .vscode/mcp.json file in your workspace with the following content:

{
  "inputs": [
    {
      "type": "promptString",
      "id": "qdrantUrl",
      "description": "Qdrant URL"
    },
    {
      "type": "promptString",
      "id": "qdrantApiKey",
      "description": "Qdrant API Key",
      "password": true
    },
    {
      "type": "promptString",
      "id": "collectionName",
      "description": "Collection Name"
    }
  ],
  "servers": {
    "qdrant": {
      "command": "uvx",
      "args": ["qdrant-llamaindex-mcp-server"],
      "env": {
        "QDRANT_URL": "${input:qdrantUrl}",
        "QDRANT_API_KEY": "${input:qdrantApiKey}",
        "COLLECTION_NAME": "${input:collectionName}"
      }
    }
  }
}

For workspace configuration with Docker, use this in .vscode/mcp.json:

{
  "inputs": [
    {
      "type": "promptString",
      "id": "qdrantUrl",
