Connect Astra Db MCP to Claude, Cursor or any other MCP client and it stops being a tab you switch to. 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. The astra db mcp mcp server is what makes that connection.
@datastax/astra-db-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Cursor — To add this to Cursor, go to Settings -> Cursor Settings -> MCPUtility — The Utility tool exposed by this serverVectorSearch — The VectorSearch tool exposed by this serverHybridSearch — Combine vector similarity search with text search for more accurate results:Configuration is passed through the environment: ASTRA_DB_APPLICATION_TOKEN, ASTRA_DB_API_ENDPOINT, ASTRA_DB_KEYSPACE, OPENAI_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
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: 1. An Astra DB Application Token 2. The Astra DB API Endpoint To learn how to get these, please [read the getting started
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Astra Db MCP's toolset — Cursor, Utility, VectorSearch and 1 more — is a fair guide to whether it matches your workflow. It is maintained by datastax; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
