MCP Ebook Server

An MCP (Model Context Protocol) server that provides AI assistants with direct access to your ebook library. Works with Claude, Cursor, and other MCP-compatible clients.

Features

  • List books in your library with metadata (title, author, language)

  • Read chapters individually or in ranges

  • Search within books or across your entire library

  • EPUB support with automatic text extraction

Why Use This Instead of LLM Training Data?

LLMs like Claude have read millions of books during training, but they don't actually have those books—they have a compressed neural representation of patterns and themes. This creates real limitations:

Question Type

LLM Training Data

MCP Ebook Server

"What's the 10th word of chapter 2?"

❌ Cannot answer

✅ Exact answer

"Quote the opening paragraph"

⚠️ Often paraphrased or hallucinated

✅ Verbatim text

"How many times is 'magic' mentioned?"

❌ Guesses

✅ Precise count

"What happens in chapter 5?"

⚠️ May confuse with similar books

✅ Actual content

"Does this book mention X?"

⚠️ Uncertain, may hallucinate

✅ Searchable proof

The core problem: LLMs retain the gist of books—major plot points, famous quotes, general themes—but lose precise details. When asked about specifics they don't know, they often hallucinate plausible-sounding answers rather than admitting uncertainty.

The solution: This MCP server gives AI direct access to the actual source text. Instead of guessing, the AI can read the exact chapter, search for specific terms, and cite real passages. No hallucinations, just the book.
