How to Use the Checkfront MCP in Vercel AI SDK

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

Initialize the Vinkius MCP Server using createMCPClient to bridge Checkfront tools with your Vercel AI SDK app. You then pass checkavailability and other tools directly into streamText before calling close() when the session ends.

Feed real-time booking availability and tour details directly into your Vercel AI SDK stream without loading spinners.

Live availability streams with Vercel AI SDK

The `check_availability` tool queries your Checkfront booking calendar directly within your Vercel AI SDK Edge Functions using this MCP Server to find open slots instantly. Your Vercel AI SDK agent feeds these vacant Checkfront spots into `streamText`, letting users watch open tour dates populate their screen as the model finds them.

Instant customer history injection

The `search_customers` tool pulls Checkfront booking histories and waiver statuses straight into your Vercel AI SDK application's active context window. This means your Vercel AI SDK agent reads past Checkfront reservation behaviors and outstanding waivers to answer support queries instantly.

Zero-latency booking detail rendering

The `get_booking` tool retrieves specific Checkfront reservation data, including assigned items and categories, directly through your active Vercel AI SDK session. Your Vercel AI SDK interface updates the customer's Checkfront receipt layout the millisecond the server returns the payload.

Setup guide

Set up Checkfront 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 Checkfront 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 Checkfront transactions",
});

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

Common questions about Checkfront MCP in Vercel AI SDK

Initialize the Vinkius MCP Server using `createMCPClient` to bridge Checkfront tools with your Vercel AI SDK app. You then pass `check_availability` and other tools directly into `streamText` before calling `close()` when the session ends.

Yes, the Vercel AI SDK runs on Edge runtimes where the Checkfront MCP Server handles inventory lookups without cold starts. Your edge-deployed Vercel AI SDK agent can check tour availability via `check_availability` instantly.

The Vercel AI SDK processes Checkfront tool outputs as they arrive from the Vinkius proxy, which queues requests to prevent hitting API thresholds. This keeps your live `list_items` calls running smoothly during high-traffic booking windows.

No, the Vercel AI SDK relies on the Vinkius MCP Server to manage the Checkfront authentication token on the backend. Your Vercel AI SDK code simply calls the tools, keeping your Checkfront API keys hidden from the client browser.

Your Checkfront customer names, contact info, and waiver signatures never persist on Vinkius servers during Vercel AI SDK runs. All transmission uses ephemeral V8 sandboxes that wipe the memory space immediately after your Vercel AI SDK session terminates.
