Requirements

• Internet connection to access RSS feeds

Installation

Installing Manually

1. Clone or download this repository:

git clone https://github.com/imprvhub/mcp-rss-aggregator
cd mcp-rss-aggregator

2. Install dependencies:

npm install

3. Build the project:

npm run build

Feed Configuration

The RSS Aggregator supports both OPML and JSON formats for feed configuration.

Using OPML (Recommended)

OPML (Outline Processor Markup Language) is a standard format used by most RSS readers to export and import feed subscriptions.

A sample OPML file with popular feeds is included in the public/sample-feeds.opml file. You can:

1. Use this file as-is
2. Edit it to add your own feeds
3. Replace it with an export from your existing RSS reader

Most RSS readers allow you to export your subscriptions as an OPML file.

Using JSON

Alternatively, you can define your feeds in a JSON file with the following format:

[
  {
    "title": "Hacker News",
    "url": "https://news.ycombinator.com/rss",
    "htmlUrl": "https://news.ycombinator.com/",
    "category": "Tech News"
  },
  {
    "title": "TechCrunch",
    "url": "https://techcrunch.com/feed/",
    "htmlUrl": "https://techcrunch.com/",
    "category": "Tech News"
  }
]

Running the MCP Server

There are two ways to run the MCP server:

Option 1: Running manually

1. Open a terminal or command prompt
2. Navigate to the project directory
3. Run the server directly:

node build/index.js

Keep this terminal window open while using Claude Desktop. The server will run until you close the terminal.

Option 2: Auto-starting with Claude Desktop (recommended for regular use)

The Claude Desktop can automatically start the MCP server when needed. To set this up:

Configuration

The Claude Desktop configuration file is located at:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

Edit this file to add the RSS Aggregator MCP configuration. If the file doesn't exist, create it:

{
  "mcpServers": {
    "rssAggregator": {
      "command": "node",
      "args": ["ABSOLUTE_PATH_TO_DIRECTORY/mcp-rss-aggregator/build/index.js"],
      "feedsPath": "ABSOLUTE_PATH_TO_YOUR_FEEDS_FILE.opml"
    }
  }
}

Important Notes:

• Replace ABSOLUTE_PATH_TO_DIRECTORY with the complete absolute path where you installed the MCP
  • macOS/Linux example: /Users/username/mcp-rss-aggregator
  • Windows example: C:\\Users\\username\\mcp-rss-aggregator
• Replace ABSOLUTE_PATH_TO_YOUR_FEEDS_FILE.opml with the path to your OPML or JSON file
  • If omitted, the sample feeds file will be used

If you already have other MCPs configured, simply add the "rssAggregator" section inside the "mcpServers" object:

{
  "mcpServers": {
    "otherMcp1": {
      "command": "...",
      "args": ["..."]
    },
    "rssAggregator": {
      "command": "node",
      "args": [
        "ABSOLUTE_PATH_TO_DIRECTORY/mcp-rss-aggregator/build/index.js"
      ],
      "feedsPath": "ABSOLUTE_PATH_TO_YOUR_FEEDS_FILE.opml"
    }
  }
}

The MCP server will automatically start when Claude Desktop needs it, based on the configuration in your claude_desktop_config.json file.

Usage

1. Restart Claude Desktop after modifying the configuration
2. In Claude, use the rss command to interact with the RSS Aggregator MCP Server
3. The MCP server runs as a subprocess managed by Claude Desktop

Troubleshooting

"Server disconnected" error

If you see the error "MCP RSS Aggregator: Server disconnected" in Claude Desktop:

1. Verify the server is running:

   • Open a terminal and manually run node build/index.js from the project directory
   • If the server starts successfully, use Claude while keeping this terminal open

2. Check your configuration:

   • Ensure the absolute path in claude_desktop_config.json is correct for your system
   • Double-check that you've used double backslashes (\\) for Windows paths
   • Verify you're using the complete path from the root of your filesystem

Tools not appearing in Claude

If the RSS Aggregator tools don't appear in Claude:

• Make sure you've restarted Claude Desktop after configuration
• Check the Claude Desktop logs for any MCP communication errors
• Ensure the MCP server process is running (run it manually to confirm)

Feeds not loading

If your feeds aren't loading properly:

• Make sure your OPML/JSON file is correctly formatted
• Check if the feedsPath in your configuration is correct
• Try running the server manually with a known good feeds file
