Ragas

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

  1. Enable the server integration.
  2. Provide your Ragas Application URL and your generated Application Token.
  3. 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.

Why Pydantic AI?

Pydantic AI validates every Ragas tool response against typed schemas, catching data inconsistencies at build time. Connect 7 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.

  • Full type safety: every MCP tool response is validated against Pydantic models, catching data inconsistencies before they reach your application

  • Model-agnostic architecture. switch between OpenAI, Anthropic, or Gemini without changing your Ragas integration code

  • Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors

  • Dependency injection system cleanly separates your Ragas connection logic from agent behavior for testable, maintainable code

FAQ

Frequently asked questions

01

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.

02

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.

03

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.

04

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

05

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

06

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your Ragas MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
