Bring Rag
to Mastra AI
Create your Vinkius account to connect Ragas to Mastra AI and start using all 7 AI tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code. No hosting, no server setup — just connect and start using.
Compatible with every major AI agent and IDE
What is the Ragas MCP Server?
Integrate Ragas with your AI agent to bring professional grade RAG (Retrieval-Augmented Generation) evaluation and tracking into your chat interface. By subscribing to this server, the AI can seamlessly manage datasets and measure LLM performance on demand.
What you can do
- Dataset Management — Upload, list, and organize evaluation datasets directly inside your environment.
- Run Evaluations — Automatically trigger Ragas evaluations on your RAG pipelines and fetch detailed scoring.
- Track Experiments — Monitor and compare iterative improvements by viewing tracked metrics across different agent versions.
- Project Organization — Associate evaluations with specific projects within your Ragas dashboard.
How it works
- Enable the server integration.
- Provide your Ragas Application URL and your generated Application Token.
- Instruct your AI to initiate evaluations or query historical metrics natively from your IDE or chat.
Who is this for?
- AI & ML Engineers — Run pipeline evaluations without context switching to a separate dashboard or writing Python evaluation scripts each time.
- QA Specialists for LLMs — Rapidly examine datasets and benchmark results to ensure hallucination rates remain low.
- Data Scientists — Compare multiple RAG configuration experiments side-by-side using unified metrics.

Frequently asked questions
How do I secure an App Token for Ragas?
Log into your provided Ragas dashboard. In your project's settings or dedicated security section, you will find the ability to generate a new Application Token. Copy it immediately, as it may only appear once.
What format is required to upload a dataset?
The tool uses common array formats through the MCP wrapper. When passing data, the AI maps arrays containing question, ground_truth and contexts natively matching Ragas base requirements.
Does the server evaluate prompts automatically during testing?
Yes. When triggering evaluations, Ragas uses its own sophisticated metrics (like Faithfulness, Answer Relevance) running internally. The MCP server simply pipes these generated reports back to your chat.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
