Perplexity

Mastra AI Content Extraction

The `convert_html_to_markdown` tool pulls the actual text out of bloated HTML payloads. You drop a raw website string into the tool, and it hands back properly formatted Markdown with the links and code blocks preserved. Workflows fail when agents get confused by DOM noise. Running this MCP Server early in your Mastra pipeline gives downstream agents a clean, deterministic text format to read. They stop skipping important paragraphs.

Predictable Node Parsing

We designed `convert_html_to_markdown` to map tags without guessing. It executes a strict conversion path for every semantic element it finds. If a scraping step fails and hands you weird markup, your Mastra AI workflow can catch the error. You set up a conditional branch to retry the extraction. The conversion itself never drops the data.

Token Optimization

Raw HTML eats your token limits and causes exponential backoff loops when APIs reject the payload. This tool strips the layout code and leaves only the content. You spread the MCP tool into your Mastra agent's toolbelt. The agent calls it automatically when it encounters a webpage, shrinking the context window footprint before it runs the next step in the sequence.

Setup guide

Set up HTML to Markdown Converter MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All HTML to Markdown Converter tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "html-to-markdown-converter-mcp-client",
  servers: {
    "html-to-markdown-converter-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "HTML to Markdown Converter Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to HTML to Markdown Converter tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent HTML to Markdown Converter transactions"
);
console.log(result.text);

Common questions about HTML to Markdown Converter MCP in Mastra AI

Install @mastra/mcp@latest. Initialize a new MCPClient with your server URL, call listTools(), and assign them to your agent. Mastra handles the transport layer automatically.

The tool itself is deterministic and rarely fails. If the source HTML is completely empty, your Mastra workflow engine will catch the empty Markdown return and trigger your configured fallback logic.

No, but you can enable it. You can set requireToolApproval if you want to inspect the converted Markdown before the agent proceeds to the next workflow step.

Headings, lists, bold text, italic text, links, and code blocks map directly to Markdown. We strip out script tags, styles, and empty layout containers.

No. The server reads the HTML strings you pipe in, runs the translation logic, and returns the Markdown. The sandbox terminates the memory state immediately after the response.
