How to Use the 4D MCP in Vercel AI SDK

Q: Can I delete 4D records via Vercel AI SDK?

The deleteentity tool allows you to remove entries based on their primary key. Ensure your agent has explicit permission before running this call.

Stream your 4D database records directly into your Vercel AI SDK frontends for live, zero-latency UI updates.

Live database queries in Vercel AI SDK

Feed `list_entities` results into your streaming components. You get record sets pushing to the browser without waiting for a full page refresh. Your users watch their data populate in real-time. The `get_entity` tool pulls specific records while the UI handles the state transitions.

Write 4D records from your Edge Functions

Trigger `create_entity` inside your serverless paths. It takes your JSON payload and commits it to the database immediately. Keep your data fresh as users interact with the interface. This MCP Server handles the connection while your code manages the logic.

Manage your 4D catalog schema

Hit `get_catalog` to inspect your table definitions programmatically. You define how the front end renders fields based on the raw structure. Update existing rows with `update_entity` when user input changes. It keeps your database state consistent with your application state.

Setup guide

Set up 4D MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all 4D tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent 4D transactions",
});

console.log(text);
await mcpClient.close();

Common questions about 4D MCP in Vercel AI SDK

You pass the server tools into the generateText function. Use the list_entities tool with your filter strings to pull the exact data your UI needs.

Yes, you can apply ORDA-style parameters like $orderby directly in your calls. This keeps the memory footprint small during streaming operations.

Vinkius isolates your traffic in a V8 sandbox. Your database credentials never touch the client-side code, keeping your entity records locked down.

The delete_entity tool allows you to remove entries based on their primary key. Ensure your agent has explicit permission before running this call.

You provide a single endpoint token through the Vinkius gateway. It signs every request, ensuring only authorized agents modify your database.
