calibre-mcp

A minimal, read-only Model Context Protocol server for a local Calibre e-book library. It wraps the calibredb CLI (--for-machine JSON output), so it needs no content server and cannot modify your library — no write tools exist.

Defaults target Windows, but it runs anywhere calibredb does (macOS/Linux) — just set the two environment variables below.

Requirements

• Calibre installed (provides calibredb).

• uv to manage the environment.

Install

git clone https://github.com/mmccarthy404/calibre-mcp.git
cd calibre-mcp
uv sync

Configuration

Set via environment variables (Windows defaults shown; change to your paths):

Run

uv run calibre-mcp        # or: uv run python calibre_mcp.py

Register with Claude Code

claude mcp add calibre --scope user -- \
  uv run --directory "/path/to/calibre-mcp" python calibre_mcp.py

Then, in a new Claude session, ask things like "search my Calibre library for Erikson" or "what are my 5 most recently added books?".
