Catalo.ai

io.github.catalo-ai/catalo

This connects Claude to Catalo.ai's book recommendation engine, giving you a way to search for books without the usual AI hallucination problem where models make up titles or authors. Instead of Claude inventing plausible-sounding books that don't exist, queries route to Catalo's curated catalog that emphasizes real but lesser-known titles. You'd reach for this when you need reliable book recommendations, want to explore beyond bestsellers, or are building reading list features where accuracy matters more than breadth. The streamable HTTP transport means it works through their API at catalo.ai/mcp rather than requiring local installation.
