Real-Time Blog Post Search for Vercel AI SDK

When you call `list_tagged_posts` or `list_blog_posts`, the data streams directly to the user interface. You don't wait for a loading spinner; the results appear instantly, making your app feel fast. This real-time stream capability is perfect for search features where users expect immediate feedback. It lets you build robust UIs that show content as it comes in from the MCP Server.

Retrieving Blog Context via Vercel AI SDK

You can quickly grab necessary background data using `get_blog_info` and `get_blog_avatar`. The UI streams the blog name, handle, and profile image URL in a single flow. This rapid display improves user experience right from the start. Because this is an Edge Function compatible MCP Server setup, you can initialize your components with key data points without hitting API limits or causing delays.

Displaying Individual Content Pieces on Vercel AI SDK

Need details for a single piece of content? Call `get_post` and watch the post body, media count, and metadata stream into your component. This granular control allows you to build custom viewers. Streaming works great here because it makes fetching detailed records feel snappy. The user sees the data appearing chunk by chunk as the AI client processes the request from the MCP Server.

Setup guide

Set up Tumblr 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 Tumblr 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 Tumblr transactions",
});

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