Automated evaluation steps in Mastra AI

Incorporate the `calculate_rouge_bleu` tool into your agent workflows to automate quality checks. If an agent's output fails to meet your similarity thresholds, you can branch the workflow to a correction step. This keeps your agents focused on target accuracy. You can build complex loops that retry generations until the ROUGE or BLEU score hits your desired mark.

Fail-safe quality control for Mastra AI

Mastra AI agents use the `calculate_rouge_bleu` tool to validate their own work before passing it to the next step. It acts as an automated editor, flagging low-quality text for manual review or immediate revision. This setup minimizes the risk of bad data moving through your pipeline. You get predictable, measurable results at every stage of the agent's task.

Mathematical validation for Mastra AI

Use the `calculate_rouge_bleu` tool to get deterministic metrics on agent performance. It provides a clear, quantitative basis for your conditional branching logic. It removes ambiguity from your agent's success criteria. By defining success through n-gram overlap, you ensure your workflows are consistently producing the right kind of content.

Setup guide

Set up LLM ROUGE & BLEU Evaluator MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All LLM ROUGE & BLEU Evaluator tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "llm-rouge-bleu-evaluator-mcp-client",
  servers: {
    "llm-rouge-bleu-evaluator-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "LLM ROUGE & BLEU Evaluator Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to LLM ROUGE & BLEU Evaluator tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent LLM ROUGE & BLEU Evaluator transactions"
);
console.log(result.text);

Common questions about LLM ROUGE & BLEU Evaluator MCP in Mastra AI

You register the server in your Mastra client configuration. Once added, you can call `calculate_rouge_bleu` as a standard tool within any of your agent's defined workflows.

Absolutely. You can write conditional logic that checks the tool's output score and instructs the agent to halt or retry if the text doesn't match the reference document.

Yes, you can use the score from the tool to decide whether to trigger a tool approval request. This lets you route suspicious or poor-quality generations to a human for final sign-off.

The client uses an endpoint token to connect to your instance. This secures the link between your agent framework and the evaluation server.

This server is ephemeral. It processes your text strings for the evaluation and then discards them immediately, ensuring your sensitive reference data isn't kept on the server.
