Mastra

Mastra is a Typescript framework to build AI applications and features quickly. It gives you the set of primitives you need: workflows, agents, RAG, integrations, syncs and evals. You can run Mastra on your local machine, or deploy to a serverless cloud.

Qdrant is available as a vector store in Mastra node to augment application with retrieval capabilities.

Setup

npm install @mastra/core

Usage

import { QdrantVector } from "@mastra/rag";

const qdrant = new QdrantVector({
  url: "https://xyz-example.eu-central.aws.cloud.qdrant.io:6333"
  apiKey: "<YOUR_API_KEY>",
  https: true
});
