altdata MCP server

MCP server for the altdata API. Gives AI agents (Claude, Cursor, Cline, ...) access to data that LLMs can't fetch natively:

• Reddit subreddits, posts, comments, search
• App Store reviews + app metadata (48 countries)
• Craigslist real-estate listings (FSBO + rentals)
• iTunes podcast directory + RSS feed parsing
