What is the DataStax Astra DB Vector MCP Server?
Connect your Astra DB instance to any AI agent and seamlessly execute complex NoSQL and vector searches through natural conversation. Built on DataStax's powerful engine, this integration gives your AI agents full contextual access to your unstructured data layer.
What you can do
- Vector Search — Perform Approximate Nearest Neighbor (ANN) similarity searches directly within your chat to find semantically related documents
- Document Management — Insert, discover, read, count, or delete exact NoSQL JSON documents across your active collections
- Collections — List and browse available tables and collections currently active in your configured Astra DB namespace
How it works
- Subscribe to this secure MCP Server
- Enter your Astra DB API Endpoint, Namespace, and Application Token
- Start querying your contextual vector database naturally from Claude, Cursor, or any compatible AI client
Your AI agent becomes a brilliant database administrator capable of exploring embeddings instantly.
Who is this for?
- AI Developers — retrieve precise contextual embeddings during advanced RAG workflows without leaving the IDE
- Data Engineers — explore and debug JSON document anomalies quickly through conversational commands
- Product Teams — inspect unstructured vector data dynamically to understand AI search results behavior
- DBAs — manage and count records across collections effortlessly

Frequently asked questions
Can my AI agent do similarity searches across vector embeddings?
Yes. Ask the agent to find documents related to a specific vector array in your target collection. The agent natively passes the numerical array directly into Astra DB's ANN engine, instantly returning the top semantically matched documents.
Does this work like standard Cassandra or is it strictly vector-only?
Both. While it excels at vector searches, the integration fully supports standard NoSQL JSON documents. You can insert, find, count, and delete standard text documents using strict JSON filters just like regular database operations.
Can I switch seamlessly between different collections?
Absolutely. Just mention the target collection by name in your prompts, and the agent adapts flawlessly. If you forget which ones exist, you can instruct it to list all available collections within your default namespace anytime.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
