Astra DB MCP Server

A Model Context Protocol (MCP) server for interacting with Astra DB. MCP extends the capabilities of Large Language Models (LLMs) by allowing them to interact with external systems as agents.

Prerequisites

You need to have a running Astra DB database. If you don't have one, you can create a free database here. From there, you can get two things you need:

An Astra DB Application Token
The Astra DB API Endpoint

To learn how to get these, please read the getting started docs.

Adding to an MCP client

Here's how you can add this server to your MCP client.

Claude Desktop

To add this to Claude Desktop, go to Preferences -> Developer -> Edit Config and add this JSON blob to claude_desktop_config.json:

{
  "mcpServers": {
    "astra-db-mcp": {
      "command": "npx",
      "args": ["-y", "@datastax/astra-db-mcp"],
      "env": {
        "ASTRA_DB_APPLICATION_TOKEN": "your_astra_db_token",
        "ASTRA_DB_API_ENDPOINT": "your_astra_db_endpoint"
      }
    }
  }
}

Windows PowerShell Users: npx is a batch command so modify the JSON as follows:

  "command": "cmd",
  "args": ["/k", "npx", "-y", "@datastax/astra-db-mcp"],

Cursor

To add this to Cursor, go to Settings -> Cursor Settings -> MCP

From there, you can add the server by clicking the "+ Add New MCP Server" button, where you should be brought to an mcp.json file.

Tip: there is a ~/.cursor/mcp.json that represents your Global MCP settings, and a project-specific .cursor/mcp.json file that is specific to the project. You probably want to install this MCP server into the project-specific file.

Add the same JSON as indiciated in the Claude Desktop instructions.

Alternatively you may be presented with a wizard, where you can enter the following values (for Unix-based systems):

Name: Whatever you want
Type: Command
Command:

env ASTRA_DB_APPLICATION_TOKEN=your_astra_db_token ASTRA_DB_API_ENDPOINT=your_astra_db_endpoint npx -y @datastax/astra-db-mcp

Once added, your editor will be fully connected to your Astra DB database.
