How to Use the LibreTranslate API MCP in Mastra AI

Q: Can I restrict tools using LibreTranslate API and Mastra AI?

You can use tool approval features to gate the translatetext tool. This ensures a human reviews or approves translations before they hit your final output.

Automated translation workflows in Mastra AI

Build multi-step agents that use `translate_text` as part of a larger chain. If a translation fails, you can set up retries within your workflow. Your agents handle translation as a discrete task. It keeps the core logic clean and modular.

Dynamic language detection for Mastra AI

Route incoming messages through `detect_language` to decide which agent branch to follow. It automates your multi-lingual support pipeline. Your workflow engine triggers the right logic based on the detected language. No hard-coding required.

Service health checks for Mastra AI

Verify the LibreTranslate API is online using `check_api_status` before starting a critical task. It prevents your agents from wasting resources on unreachable endpoints. You can build a conditional check that halts the workflow if the translation service is unavailable.

Setup guide

Set up LibreTranslate API 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 LibreTranslate API 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: "libretranslate-api-mcp-client",
  servers: {
    "libretranslate-api-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent LibreTranslate API transactions"
);
console.log(result.text);

Common questions about LibreTranslate API MCP in Mastra AI

Import the MCP client and register the server URL in your agent configuration. You then spread the available tools into the agent's tool list.

Yes. Because Mastra AI handles retries natively, you can wrap your translation calls in an error handler to manage transient network issues.

You can use tool approval features to gate the `translate_text` tool. This ensures a human reviews or approves translations before they hit your final output.

The server uses standard MCP, so you just need to point the client to the correct endpoint. Mastra AI detects the transport automatically.

The server handles text content in memory for the duration of the translation request. It does not persist your text records in any database.
