mcp-server-motherduck MCP Server: Connecting AI Applications to Data Sources Efficiently

Overview: What is mcp-server-motherduck MCP Server?

The mcp-server-motherduck MCP server is an essential component for integrating AI applications, particularly those compatible with the Model Context Protocol (MCP), with data sources hosted on MotherDuck and local DuckDB. This server acts as a bridge between various AI clients and these structured data environments, enabling seamless interaction through standardized protocols.

🔧 Core Features & MCP Capabilities

Resources, Prompts, and Tools

The mcp-server-motherduck includes essential resources, prompts, and tools to facilitate effective data access and manipulation. It supports a single prompt designed for initializing connections:

• Duckdb-motherduck-initial-prompt: This prompt initiates the necessary connection by setting up a link between MotherDuck or local DuckDB and the AI application.

Additionally, it provides three core tools that enable interaction with the data environment:

1. initialize-connection: This tool creates a connection to either a local DuckDB instance or MotherDuck.
2. read-schemas: Retrieves table schemas from a specific DuckDB/MotherDuck database, essential for understanding the database structure before executing queries.
3. execute-query: Executes SQL queries on the MotherDuck (or DuckDB) database.

AI Application Compatibility

The MCP client compatibility matrix highlights that mcp-server-motherduck is fully compatible with key AI applications:

• Claude Desktop: Full support for resources, tools, and prompts.
• Continue: Full support as well.
• Cursor: Limited compatibility; tool-specific integration only.

This diagram illustrates the flow of interaction between an AI application, utilizing MCP client libraries to communicate via the Model Context Protocol, through the mcp-server-motherduck, and finally reaching MotherDuck or local DuckDB for data operations.

⚙️ MCP Architecture & Protocol Implementation

The architecture of mcp-server-motherduck is designed to harmonize with the Model Context Protocol. The server receives commands from MCP clients, which trigger specific actions like connection initialization, schema reading, and query execution. This ensures that all interactions follow standardized methods, making integration straightforward yet flexible.

🚀 Getting Started with Installation

To install mcp-server-motherduck, you will need to configure it within your environment as follows:

Setup Configuration

1. Create a .claude_desktop_config.json file:

   • On MacOS: ~/Library/Application\ Support/Claude/claude_desktop_config.json
   • On Windows: %APPDATA%/Claude/claude_desktop_config.json

2. Edit the server configuration section:

"mcpServers": {
  "mcp-server-motherduck": {
    "command": "uvx",
    "args": [
      "mcp-server-motherduck"
    ],
    "env": {
      "motherduck_token": "",
      "HOME": ""
    }
  }
}

3. Ensure necessary environment variables:
   • motherduck_token: Set a MotherDuck token to authenticate.
   • HOME: Specify the home path directory for DuckDB.

💡 Key Use Cases in AI Workflows

Real-World Scenario: Data Exploration and Analysis

Imagine utilizing an AI application like Claude Desktop to explore a MotherDuck database. By configuring the MCP server with mcp-server-motherduck, you can effortlessly connect, retrieve schema information, and execute queries directly from your AI client.

1. Connection Initialization:
   • Use initialize-connection to establish a link between your AI application and MotherDuck.
2. Schema Retrieval:
   • Employ read-schemas to understand available tables and columns in the database.
3. Query Execution:
   • Run custom SQL queries through execute-query.

Step-by-Step Implementation

1. Connect to Database:

   initialize-connection "MotherDuck"
   

2. Retrieve Schema:

   read-schemas "databases/sales"
   

3. Execute Query:

   execute-query "SELECT * FROM sales LIMIT 10;"
   

🔌 Integration with MCP Clients

The following is a compatibility matrix for key MCP clients:

MCP Client	Resources	Tools	Prompts	Status
Claude Desktop	✅	✅	✅	Full Support
Continue	✅	✅	✅	Full Support
Cursor	❌	✅	❌	Tools Only

This matrix indicates that all MCP clients can leverage the resources such as duckdb-motherduck-initial-prompt, access tools for connection management and schema retrieval, but note limited direct prompts support from Cursor.

📊 Performance & Compatibility Matrix

The performance and compatibility are robust across supported platforms:

• MCP Clients: Claude Desktop and Continue offer full support.
• Platforms: macOS and Windows environments are fully compatible with the required configurations.

These details ensure that AI application developers can trust this MCP server for diverse uses.

🛠️ Advanced Configuration & Security

Environment Variables

Setting up appropriate environment variables ensures secure and functional connections:

export motherduck_token="your_motherduck_token"
export HOME="/path/to/home/directory"

Enhancing Security

• Token Management: Store the MotherDuck token securely, using OS-specific secure storage methods.
• Network Privacy: Ensure that communication between the AI application and server adheres to privacy protocols.
