Real-time subscriber management in AI SDK

Feed your Kit (ConvertKit) data straight into your UI components without the delay of traditional REST calls. When your user asks to add a person, your agent uses `add_subscriber_to_form` to fire the request, and the result updates your frontend state immediately. This MCP Server provides the raw hooks to keep your interface in sync with your mailing list. You handle the state, the server handles the API heavy lifting.

Dynamic metadata updates via AI SDK

Keep your user profiles current by piping data through `update_subscriber`. Your agent can parse incoming chat messages and map them to custom fields instantly. Stop writing manual parsing logic for every form submission. Use this MCP Server to bridge the gap between natural language input and your backend database records.

Subscriber intelligence in AI SDK

Get the full picture of your audience by querying `get_subscriber_details` or `list_subscribers`. Your agent gains instant context on who it is talking to. Displaying this data in your Vercel-hosted app helps users make informed decisions. It puts the power of your entire subscriber base right inside the chat window.

Setup guide

Set up Kit (ConvertKit) 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 Kit (ConvertKit) 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 Kit (ConvertKit) transactions",
});

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

Common questions about Kit (ConvertKit) MCP in Vercel AI SDK

Install the MCP client via npm and point it to your Vinkius endpoint. You then pass the tools from this MCP Server into your `generateText` or `streamText` functions.

Yes, the tools are fully compatible with streaming responses. Your UI will show the tool call execution in real-time as the agent processes the request.

Vinkius handles authentication via a single endpoint token, ensuring your credentials never touch your frontend code. We treat subscriber emails and IDs as sensitive, ephemeral data that never persists on our servers.

Absolutely. You can use the `update_subscriber` tool to modify any custom field defined in your account directly through your agent's interface.

The MCP Server manages the connection, but you should implement standard debouncing in your frontend. This prevents excessive API calls during rapid-fire chat interactions.
