Live booking management

Your AI client handles scheduling logic while the user watches the calendar state update in real-time. Use `create_booking` or `reschedule_booking` to push changes directly to your UI. This MCP Server provides the raw data needed to render availability. By piping `get_slots` into your stream, you show users exactly when they can book without leaving your app.

Instant event visibility

Stop guessing if a slot is open. Your interface can query `list_bookings` to show upcoming meetings immediately as the AI processes the user request. Everything happens inside your Edge Functions. Because the tools are exposed as typed functions, your UI reacts instantly to changes in `list_event_types`.

Automated availability logic

Manage complex scheduling rules programmatically. Use `create_event_type` to define new meeting parameters that your agent can offer to users. Check your credits balance with `get_credits` to ensure your account remains active. This keeps your agent running without manual intervention.

Setup guide

Set up Cal.com 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 Cal.com 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 Cal.com transactions",
});

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

Common questions about Cal.com MCP in Vercel AI SDK

Install the MCP client package via npm and initialize it with your server URL. Pass the tools retrieved from the server into your generateText or streamText calls to give your agent access to booking data.

Yes. Since the tools return standard responses, you can wrap them in your own error handling logic. If `create_booking` fails, your agent can catch the error and explain the issue to the user.

Absolutely. The tool outputs are designed to be consumed by the stream. Your UI will update as soon as the tool execution finishes.

Your API key is handled via a secure transport layer. We never store your credentials on our servers; they stay within your environment.

You control the tool list before passing it to your agent. Simply filter the array returned by the MCP client to restrict access to specific functions like `cancel_booking`.
