Run ANN similarity queries in Claude Desktop

The `vector_search` tool executes Approximate Nearest Neighbor queries against your database. You give the client a target array. It hits the database and pulls back the closest matching records based on their vector embeddings. This MCP Server replaces manual database querying. You stop writing custom Python scripts to test your vector data. The client formats the vector array, sends the request, and reads the raw JSON response right in the conversation window.

Read and write NoSQL data

Standard CRUD operations run through the `insert_document`, `find_documents`, and `find_one_document` tools. Your agent writes new records, complete with pre-generated `$vector` keys, straight into the active namespace. It handles the JSON formatting entirely. You get immediate confirmation when a record hits the database. The `delete_document` tool removes specific entries when you need to clean up test data. Natural language prompts control the entire document lifecycle.

Map out your Astra DB architecture

Firing the `list_collections` tool returns every available collection within your current namespace. Your client uses this to understand the schema before attempting any data retrieval. It knows exactly where to look. Tracking volume happens through the `count_documents` tool. You ask for the total size of a specific collection. The agent checks the database and returns the exact integer count. You get immediate visibility into your dataset scale.
