# Hacker News MCP Server

A Model Context Protocol (MCP) server that provides tools for fetching stories from Hacker News. This server parses the HTML content from news.ycombinator.com and provides structured data for different types of stories (top, new, ask, show, jobs).

## Features

- Fetch different types of stories (top, new, ask, show, jobs)
- Get structured data including titles, URLs, points, authors, timestamps, and comment counts
- Configurable limit on number of stories returned
- Clean error handling and validation

## Installation

1. Clone the repository:
```bash
git clone https://github.com/pskill9/hn-server
cd hn-server
```

2. Install dependencies:
```bash
npm install
```

3. Build the server:
```bash
npm run build
```

4. Add to your MCP settings configuration file (location depends on your system):

For VSCode Claude extension:
```json
{
  "mcpServers": {
    "hacker-news": {
      "command": "node",
      "args": ["/path/to/hn-server/build/index.js"]
    }
  }
}
```

## Usage

The server provides a tool called `get_stories` that can be used to fetch stories from Hacker News.

### Tool: get_stories

Parameters:
- `type` (string): Type of stories to fetch
  - Options: 'top', 'new', 'ask', 'show', 'jobs'
  - Default: 'top'
- `limit` (number): Number of stories to return
  - Range: 1-30
  - Default: 10

Example usage:
```typescript
use_mcp_tool with:
server_name: "hacker-news"
tool_name: "get_stories"
arguments: {
  "type": "top",
  "limit": 5
}
```

Sample output:
```json
[
  {
    "title": "Example Story Title",
    "url": "https://example.com/story",
    "points": 100,
    "author": "username",
    "time": "2024-12-28T00:03:05",
    "commentCount": 50,
    "rank": 1
  },
  // ... more stories
]
```

## Integrating with Claude

To use this MCP server with Claude, you'll need to:

1. Have the Claude desktop app or VSCode Claude extension installed
2. Configure the MCP server in your settings
3. Use Claude's natural language interface to interact with Hacker News

### Configuration

For the Claude desktop app, add the server configuration to:
```json
// ~/Library/Application Support/Claude/claude_desktop_config.json (macOS)
// %APPDATA%\Claude\claude_desktop_config.json (Windows)
{
  "mcpServers": {
    "hacker-news": {
      "command": "node",
      "args": ["/path/to/hn-server/build/index.js"]
    }
  }
}
```

For the VSCode Claude extension, add to:
```json
// VSCode Settings JSON
{
  "mcpServers": {
    "hacker-news": {
      "command": "node",
      "args": ["/path/to/hn-server/build/index.js"]
    }
  }
}
```

### Example Interactions

Once configured, you can interact with Claude using natural language to fetch Hacker News stories. Examples:

- "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"

Claude will automatically use the appropriate parameters to fetch the stories you want.

- `author` (string): Username of the poster
- `time` (string): Timestamp of when the story was posted
- `commentCount` (number): Number of comments
- `rank` (number): Position in the list

## Development

The server is built using:
- TypeScript
- Model Context Protocol SDK
- Axios for HTTP requests
- Cheerio for HTML parsing

To modify the server:

1. Make changes to `src/index.ts`
2. Rebuild:
```bash
npm run build
```

## Error Handling

The server includes robust error handling for:
- Invalid story types
