mcp-hacker-news

A Model Context Protocol (MCP) server for Hacker News built with TypeScript.

This MCP server acts as a bridge between the official Hacker News API and AI-powered tools that support the Model Context Protocol, such as Claude and Cursor.

It enables these tools to fetch and interact with live Hacker News data (posts, comments, users) via standardized MCP endpoints.

Usage with Claude Desktop

Add to your Claude Desktop configuration (claude_desktop_config.json):

{
  "mcpServers": {
    "mcp-hacker-news": {
      "command": "npx",
      "args": ["-y", "mcp-hacker-news"]
    }
  }
}

Features

• Integrates with the official Hacker News API to fetch posts, comments, and user information.
• Exposes standard Model Context Protocol endpoints for seamless integration with Claude, Cursor, and other LLM-based tools.
• Fetches the latest Hacker News data for AI and automation workflows.

Requirements

• Node.js version 18 or higher is required.
• npm or pnpm as a package manager.

⚠️ If you are unsure about your Node.js version, run node --version in your terminal. Make sure it shows v18.x.x or higher.

Resources

This MCP server exposes the following fixed resources, each corresponding to a core Hacker News endpoint:

| Resource URI | Description | Hacker News API Endpoint | | ------------------- | -------------------------- | ------------------------ | | hackernews://top | Top stories | /v0/topstories | | hackernews://new | Newest stories | /v0/newstories | | hackernews://best | Best (algorithmic) stories | /v0/beststories |

These three collections match the main list endpoints officially provided by the Hacker News API.
Other types of stories (Ask HN, Show HN, Jobs, etc.) and item-specific lookups are available as tools (see below), allowing for flexible querying with custom parameters.

Tools

The following tools are available for advanced or parameterized queries. These allow you to fetch other Hacker News content beyond the fixed resources above:

| Tool Name | Description | | ------------------ | ----------------------------------------------- | | getTopStories | Fetch top stories (customizable limit) | | getBestStories | Fetch best stories (customizable limit) | | getNewStories | Fetch newest stories (customizable limit) | | getAskHNStories | Fetch "Ask HN" posts | | getShowHNStories | Fetch "Show HN" posts | | getJobStories | Fetch job postings | | getItem | Retrieve a specific item (story, comment, etc.) | | getUser | Retrieve a user profile by username | | getComments | Fetch comments for a specific item | | getMaxItemId | Get the current maximum item ID | | getUpdates | Fetch recently updated items and profiles |

Check the code or inline documentation for supported arguments and usage examples for each tool.

Tip:
Make sure you have pnpm installed for development setup.
You can substitute npm or yarn if you prefer, but pnpm is recommended for consistency.
