Set up this RSS MCP server for my Claude Desktop.

Repo: https://github.com/lionkiii/rss-mcp-marketing

Do all of the following:
1. Clone the repo into a sensible folder (e.g. ~/mcp-servers/rss-mcp-marketing) if it isn't already cloned, then cd into it.
2. Run `npm install` and `npm run build`. Confirm `dist/index.js` exists.
3. Find the absolute path to my node binary (`which node`; if it is under nvm use that full path, because Claude Desktop does not load my shell PATH).
4. Locate my Claude Desktop config:
   - macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   - Windows: %APPDATA%\Claude\claude_desktop_config.json
   Create the file with `{}` if it does not exist. Back it up first.
5. IMPORTANT: fully quit Claude Desktop before editing the config, because a running Claude Desktop rewrites the file on write and will discard my changes. On macOS quit it with `osascript -e 'tell application "Claude" to quit'`.
6. Merge (do not overwrite) an "mcpServers" entry named "rss-feeds" whose "command" is my absolute node path and whose "args" is the absolute path to dist/index.js. Keep the JSON valid and preserve any existing config keys and other mcpServers.
7. Relaunch Claude Desktop and verify the config still contains the rss-feeds entry after launch, and that a node process running dist/index.js was spawned.
8. Tell me to try: "fetch the latest marketing blogs".

npm install
npm run build

{
  "mcpServers": {
    "rss-feeds": {
      "command": "node",
      "args": ["/absolute/path/to/RSS/dist/index.js"]
    }
  }
}
