How to Use the Cognito Forms MCP in Vercel AI SDK

Q: How do I connect Cognito Forms to my Vercel AI SDK project?

Install the @ai-sdk/mcp package and initialize the client with your Vinkius endpoint. Pass mcpClient.tools() into generateText or streamText to let your model call Cognito Forms MCP tools.

Q: Can Vercel AI SDK stream Cognito Forms entry updates live?

Yes. When your model calls updateentry, the Vercel AI SDK streams the tool execution status directly to the frontend so your users see the update happen in real time.

Q: Do I need to close the connection after querying Cognito Forms?

Yes, you must always call mcpClient.close() once your text generation completes. This prevents hanging HTTP connections in your serverless environment.

Feed live Cognito Forms data directly into your React components using Vercel AI SDK.

Stream Cognito Forms data live with Vercel AI SDK

The `list_entries` tool feeds raw submission data directly into your streaming UI components without loading spinners. Your user sees form records populate line-by-line as your app fetches them. You configure this by passing the MCP Server tools array into `streamText`. When a user asks for recent submissions, the SDK resolves the tool call and renders the UI state immediately.

Look up form fields on the fly

The `get_form_fields` tool pulls the exact field structure of any online form so your AI client knows what fields to populate. It maps out text boxes, dropdowns, and calculations dynamically before generating a new record. You don't hardcode schemas anymore. This MCP client gets the live form architecture, lets the LLM construct a valid payload, and runs `create_entry` to post it.

Real-time search and entry updates

The `search_entries` tool scans your Cognito Forms database for specific submissions based on user queries. Your agent runs this search, processes the results, and can immediately run `update_entry` to fix typos or change statuses. The MCP connection stays light while processing heavy form updates. The SDK handles the connection, meaning your serverless backend stays light while processing heavy form updates.

Setup guide

Set up Cognito Forms 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 Cognito Forms 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 Cognito Forms transactions",
});

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