What is the Calibre-Web MCP Server?
Connect your Calibre-Web instance to any AI agent and interact with your digital book collection using natural language. This server provides tools to navigate your library structure and prepare books for e-reader synchronization.
What you can do
- OPDS Catalog Access — Retrieve the main OPDS XML feed to browse your entire library structure, categories, and recent additions.
- Shelf Browsing — Query specific shelf IDs to list books within curated collections or user-defined categories.
- Kobo Synchronization — Fetch structured metadata and secure download links optimized for Kobo devices using your dedicated sync token.
- Library Inspection — Use the AI to find specific book entries and metadata within your self-hosted instance.
How it works
- Subscribe to this server
- Enter your Calibre-Web instance URL and optional credentials
- Start exploring your library from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Avid Readers — quickly find books in large collections without manual searching
- Digital Librarians — verify shelf contents and catalog structures via chat
- Kobo Users — automate the retrieval of sync metadata for your e-reader devices

Frequently asked questions
Can I browse my entire library structure through the AI?
Yes. By using the get_opds_catalog tool, the agent retrieves the root XML feed of your Calibre-Web instance, allowing it to see categories, authors, and series as defined in your OPDS settings.
How do I list books from a specific custom shelf?
You can use the get_opds_shelf tool by providing the specific shelf_id. The AI will then return the list of books and metadata associated with that particular shelf.
Does this support syncing my Kobo e-reader?
Yes. If you provide your CALIBRE_WEB_KOBO_TOKEN, you can use the sync_kobo_library tool to get structured metadata and download links specifically formatted for Kobo device synchronization.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
