RSS Crawler acts as an MCP (Message Chain Protocol) server, bridging the gap between RSS feeds and Large Language Models. It retrieves and caches RSS feeds, making them accessible to LLMs through a seamless MCP integration. The server supports feed filtering by category, source, or keywords, and offers comprehensive API endpoints for feed management, including adding, updating, and deleting feeds. It also integrates with Firecrawl for fetching articles, providing a robust solution for delivering up-to-date information to LLMs.
