Hacker News MCP Server: Integrating with Model Context Protocol

Overview: What is Hacker News MCP Server?

The Hacker News MCP Server is a specialized tool that adheres to the Model Context Protocol (MCP) standard, designed to facilitate seamless integration between AI applications like Claude Desktop and specific data sources. This server provides a structured API for fetching information from Hacker News, one of the most popular technology discussion forums on the web. By leveraging MCP, it enables developers and end-users to leverage the vast array of features and data provided by hacker news in their AI workflows.

🔧 Core Features & MCP Capabilities

The Hacker News MCP Server offers a range of core features that make it an indispensable tool for developers and users who wish to interact with Hacker News data through controlled API calls. These features include:

Story Fetching Capabilities: The server can fetch different types of stories such as 'top', 'new', 'ask', 'show', and 'jobs'. Developers can specify the type of story they want to retrieve, along with a configurable limit on the number of stories returned.
Structured Data Output: Each fetched story is represented in a structured JSON format that includes key attributes like title, URL (optional), points, author, timestamp, comment count, and rank. This ensures consistent and machine-readable data for seamless integration into various systems.
Error Handling & Validation: The server implements comprehensive error handling mechanisms to ensure robustness against invalid story types, network failures, HTML parsing issues, and incorrect parameter values.

⚙️ MCP Architecture & Protocol Implementation

Model Context Protocol (MCP) Overview

Model Context Protocol (MCP) is a standardized framework that allows AI applications to interact with various data sources and tools through a unified interface. MCP servers like the Hacker News server provide APIs that conform to this protocol, enabling seamless integration and consistent behavior across different platforms.

Compatibility with MCP Clients

The Hacker News MCP Server is designed to be compatible with various MCP clients, including:

Claude Desktop: Full support for all MCP server functionalities.
Continue: Seamless integration capabilities available.
Cursor: Currently limited to data tool usage only.

🚀 Getting Started with Installation

Step 1: Clone the Repository

To start using the Hacker News MCP Server, you first need to clone its repository and install the necessary dependencies. Execute the following commands in your terminal:

git clone https://github.com/pskill9/hn-server
cd hn-server

Step 2: Install Dependencies

With the project cloned, proceed to install all required npm packages by running:

npm install

Step 3: Build the Server

The next step is to build your local server. This allows you to run a locally hosted instance of the MCP server that can be used as a data source within AI applications.

npm run build

Step 4: Configure in MCP Settings

For VSCode Claude extension:

{
  "mcpServers": {
    "hacker-news": {
      "command": "node",
      "args": ["/path/to/hn-server/build/index.js"]
    }
  }
}

💡 Key Use Cases in AI Workflows

Use Case 1: News Aggregation for Knowledge Graphs

One common use case involves integrating the Hacker News MCP Server into a knowledge graph generation system. This allows AI applications to query Hacker News content regularly and add relevant stories to the graph based on their popularity, relevance, or specific tags.

Example Workflow:

AI Application: A knowledge management platform.
MCP Client: VSCode Claude extension.
MCP Server: Hacker News MCP Server.
Data Source: Hacker News API.

Use Case 2: Custom Story Summarizers

Another use case is to develop custom summarization models that can process and provide summaries of important stories from Hacker News for users. This can be particularly useful in environments where real-time or near-real-time analysis is required.

Example Workflow:

AI Application: A real-time news summarization tool.
MCP Client: Claude Desktop app.
MCP Server: Hacker News MCP Server.
Data Source: Hacker News stories.

🔌 Integration with MCP Clients

Example Interactions

Once the server is configured, users can interact with it using natural language or API calls. Here are some example interactions:

"Show me the top 5 stories from Hacker News."
"What are the latest Ask HN posts?"
"Get me the top Show HN submissions from today."

These commands will fetch the appropriate data and return it in a structured JSON format.
