Perplexity

Vercel AI SDK DOM Parser

The `convert_html_to_markdown` tool takes raw HTML strings and forces them into strict Markdown. You pass the heavy, nested markup your scraper pulled, and it strips the junk while keeping headings, links, lists, and code blocks intact. LLMs choke on raw HTML. They start hallucinating or skipping chunks of text when the token count gets too high. By running this MCP Server before you call your streaming functions, your AI actually reads the whole page.

Deterministic Tag Mapping

We built `convert_html_to_markdown` to map HTML tags predictably. It does not guess what a div means. It looks at the actual semantic structure and outputs the exact Markdown equivalent every single time. You get zero data loss. When you pipe the output into a Next.js UI component, the formatting holds up. Your users see real-time, readable text instead of broken HTML tags bleeding into the chat window.

Massive File Handling

This tool processes massive HTML files that would normally break your edge functions. It parses the DOM locally on the MCP server and returns only the Markdown text. Your Vercel AI SDK client stays lightweight. You stop wasting expensive LLM tokens on inline CSS and tracking scripts. The AI gets the actual content, and you get faster response times.

Setup guide

Set up HTML to Markdown Converter 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 HTML to Markdown Converter 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 HTML to Markdown Converter transactions",
});

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

Common questions about HTML to Markdown Converter MCP in Vercel AI SDK

Install @ai-sdk/mcp. Use createMCPClient with your endpoint URL, call mcpClient.tools(), and pass the array to your generateText call. Close the client when the stream finishes.

Because LLMs skip data when reading raw HTML. Converting it to Markdown first cuts your token usage and stops the AI from hallucinating over broken div tags.

Yes. You configure the HTTP transport in your MCP setup. The actual parsing happens on our infrastructure, so your edge function does not run out of memory processing massive DOM trees.

The tool preserves them. It maps standard HTML formatting into valid Markdown syntax so your frontend renders it correctly.

The server receives your raw HTML payload, converts it, and immediately discards it. We do not log the text you send or the Markdown we return. The instance runs in a stateless V8 isolate.
