Apple Books MCP is a Model Context Protocol server, published on PyPI as apple-books-mcp under the Apache 2.0 licence, that gives an assistant structured access to a local Apple Books library. Read tools cover four areas. Collection tools list collections, return the books inside one, describe a collection and search collections by title. Book tools list all books, describe a single book with metadata, progress, annotation count and description, list its annotations in chapter order, search by title and filter by genre. Reading-status tools return books in progress, finished books, unstarted books and the most recently opened ones. Annotation tools browse every highlight and note grouped by book or as a flat recent list, describe a single annotation, search notes or search across highlights, notes and surrounding text, filter highlights by colour and select annotations within a date range. A library statistics tool returns a summary of reading activity. Two features make highlights useful in conversation: one returns the paragraph around a highlight with the marked text delimited and a configurable number of characters before and after, and another reads Apple Books' automatic bookmark to report the chapter the user last left off. Book content tools list a table of contents and return plain-text chapter content with offset and length slicing, but only for non-DRM EPUBs such as imported files, Project Gutenberg or Standard Ebooks; FairPlay-protected store purchases return a clear error and iCloud-only books report that they are not downloaded. Collection editing is off by default and enabled with a command-line flag. Because Apple offers no automation API for collections, those writes go straight to the library database behind guard rails: they refuse while Books is running, take a WAL-safe backup first, validate the schema and abort on drift, and touch only user-created collections. Deleting a collection leaves its books alone.
