How to Use the 4D MCP in Mastra AI

Q: How do I query specific 4D records in Mastra AI?

Use the listentities tool with your $filter parameters. This allows your agent to find specific rows before performing updates.

Build resilient 4D database workflows in Mastra AI with automatic retry logic and conditional branching.

Automate 4D records with Mastra AI

Chain `create_entity` calls into your workflows. If a network blip occurs, the framework handles the retry until the record lands in 4D. Define your logic branches based on the output of `get_entity`. You decide what happens next when a record update succeeds or fails.

Complex data manipulation in Mastra AI

Run `update_entity` within a multi-step process. You can validate data before committing the final JSON payload to the database. Keep your workflows clean by using `list_entities` to fetch context for your agents. It pulls the necessary state into your agent memory.

Inspect 4D structures using Mastra AI

Call `get_catalog` at the start of your workflow. Your agent reads the schema to understand which fields exist before it tries to write data. Clean up old records with `delete_entity` once your archival step finishes. It automates your database hygiene without manual intervention.

Setup guide

Set up 4D 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 4D 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: "4d-mcp-client",
  servers: {
    "4d-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent 4D transactions"
);
console.log(result.text);

Common questions about 4D MCP in Mastra AI

You add the server URL to your MCPClient configuration. The agent then dynamically maps the tools into its available action set.

Mastra handles exponential backoff automatically if a call to the server fails. You define the policy to keep your 4D operations stable.

Every interaction is encrypted through the Vinkius managed endpoint. Your raw database records are never exposed to third-party logs.

You can enable requireToolApproval for any 4D tool. The agent pauses until a human signs off on the specific database change.

Use the list_entities tool with your $filter parameters. This allows your agent to find specific rows before performing updates.
