Fault-Tolerant Workflows with Mastra AI

Network drops happen when running AI21 text operations on massive datasets. Mastra AI wraps the `summarize` tool in an automatic retry layer with exponential backoff. If an API call fails, the workflow catches it and tries again gracefully. You stop writing custom error handling for third-party endpoints. Just initialize the MCP client and spread the tools into your agent. The framework manages the connection stability for you.

Conditional Routing for Text Tasks

Sometimes an AI21 document processing pipeline needs to fix text before summarizing it. You can build a branch that runs `grammar_corrections` first, checks the output quality, and then decides whether to call `paraphrase`. Mastra lets you chain these operations logically. Use `segmentation` to break paragraphs into sentences, then loop through them. The workflow engine tracks the state across every step.

Jamba Models in Production MCP Servers

Hooking up the `chat_completion` tool gives your Mastra agents access to the Jamba 1.5 large and mini models. They can digest context and generate responses within your automated pipelines. When you need to build RAG systems, the `embed_texts` tool is ready. You pass an array of strings, specify if they are queries or documents, and the agent stores the resulting vectors.

Setup guide

Set up AI21 Studio 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 AI21 Studio 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: "ai21-studio-mcp-client",
  servers: {
    "ai21-studio-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "AI21 Studio Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to AI21 Studio tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent AI21 Studio transactions"
);
console.log(result.text);

Common questions about AI21 Studio MCP in Mastra AI

Run npm install @mastra/mcp@latest. Create a new instance pointing to your Vinkius endpoint, then call mcpClient.listTools() to load the capabilities.

The framework catches 429 errors automatically. It pauses the workflow and retries the text_completion or summarize calls using exponential backoff.

You can configure requireToolApproval on the MCP client. This pauses the workflow so a human can review the paraphrase results before the agent continues.

Mastra auto-detects the best connection method. It typically defaults to Streamable HTTP or SSE for Vinkius-hosted endpoints.

Vinkius routes your private document strings and chat logs through a zero-trust V8 isolate. The sandbox spins up, executes the tool, and vanishes without logging the payload.
