Perplexity

Automated object flattening in workflows

The `transform_dot_object` tool allows your Mastra AI agents to flatten nested JSON during a multi-step workflow. This is vital when moving data between disparate APIs that require different schema shapes. By including this tool in your agent's toolkit, you ensure that every step of your workflow receives data in the exact format it needs. It removes the risk of manual parsing errors in your logic chains.

Reliable reconstruction for API payloads

When your workflow needs to send data to an external service, use `transform_dot_object` to unflatten your state into the required nested JSON. This ensures your outgoing API calls always match the expected schema. It handles complex nesting automatically, so your workflow stays lean. If the transformation fails, the tool provides a clear error, allowing your agent to trigger a retry or fallback process immediately.

Conditional data processing

Chain this tool with Mastra AI's conditional logic to decide when to flatten or unflatten data. You can inspect the structure of your incoming data and route it through the transformer only when necessary. This keeps your agent operations efficient. You avoid unnecessary compute time and ensure that only correctly structured data moves to the next stage of your automated pipeline.

Setup guide

Set up Dot Object Transformer 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 Dot Object Transformer 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: "dot-object-transformer-mcp-client",
  servers: {
    "dot-object-transformer-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent Dot Object Transformer transactions"
);
console.log(result.text);

Common questions about Dot Object Transformer MCP in Mastra AI

Import the MCP client and add the Dot Object Transformer as a tool provider in your agent configuration. Your agents will gain the ability to call it within their workflow steps.

Yes, because it is an MCP tool, it integrates with the Mastra AI retry engine. If a transformation fails, the agent can automatically attempt the call again.

The server focuses on structural transformation. Use it to normalize your data shapes, but handle specific field validation or cleaning tasks separately in your agent logic.

It runs as a separate MCP server, so it doesn't impact your main agent execution loop. It processes transformations efficiently, keeping your workflow latency low.

Your JSON payloads are processed in an ephemeral memory space that clears after every call. The server never logs or persists the data it transforms, keeping your workflow information private.
