Automate Hacker News discovery in Mastra AI

Use `top_stories` to trigger your agent workflows based on current trends. You can set up conditional logic to only act when a story hits a specific comment threshold. Your agents handle the heavy lifting, checking the front page and deciding whether to fetch more details based on your defined business rules.

Parse thread depth with Mastra AI tools

Call `get_item` within a Mastra workflow to extract specific data points from a post. It turns raw ID lookups into structured information for your agents. This is how you build an automated researcher. The agent pulls the item, reads the context, and moves to the next step in your pipeline without needing your input.

Track latest submissions via MCP Server

Keep your agents informed by polling `new_stories` through your Mastra engine. It provides a constant stream of fresh identifiers for immediate processing. This tool is useful for building alert systems. If a new submission matches your topic filter, the agent can notify your team instantly.

Setup guide

Set up Hacker News 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 Hacker News 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: "hacker-news-mcp-client",
  servers: {
    "hacker-news-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent Hacker News transactions"
);
console.log(result.text);

Common questions about Hacker News MCP in Mastra AI

Add the server to your agent definition and spread the tools into the agent's toolset. Mastra treats these as native functions within your workflow steps.

Yes, use the requireToolApproval setting. This lets you review what the agent intends to fetch before it executes the tool call.

Mastra handles retries automatically if a tool call fails. This keeps your news gathering persistent even if the connection blips.

The server only touches public story and comment data. Your local Mastra agent remains the sole owner of the logic and context.

Wrap your tool calls in standard error handling blocks. Mastra provides clear feedback if an ID lookup fails or the API rate limit is reached.
