Show HN: Booklife-MCP – MCP server unifying Libby, Hardcover, and your TBR(github.com)

  The problem: I use three separate platforms to manage my reading life. Libby for borrowing, Hardcover for tracking, and I had no single view
  of what I want to read next. Switching between apps to check availability, update status, or decide what to read was friction I wanted to
  eliminate.

  booklife-mcp exposes 27 tools over MCP stdio that let you:

  - Search your library catalog and place holds from a conversation
  - Sync returned Libby loans as "read" in Hardcover automatically
  - Maintain a unified TBR list across Hardcover want-to-read, Libby holds, Libby tags, and physical books
  - Get content-based recommendations using enriched theme/mood metadata
  - Check "what's the best way to read this?" (library availability vs. buy)

  Technical notes:
  - Go, single binary, SQLite for local cache
  - Hardcover via GraphQL, Libby via reverse-engineered OverDrive API, Open Library REST
  - Progressive disclosure pattern — tools return summaries first, drill down on request
  - Also ships as a Claude Code plugin with skills/slash commands
