MCP Open Library

Overview

This project implements an MCP server that provides tools for AI assistants to interact with the Open Library. It allows searching for book information by title, searching for authors by name, retrieving detailed author information using their Open Library key, and getting URLs for author photos using their Open Library ID (OLID). The server returns structured data for book and author information.

Features

• Book Search by Title: Search for books using their title (get_book_by_title).
• Author Search by Name: Search for authors using their name (get_authors_by_name).
• Get Author Details: Retrieve detailed information for a specific author using their Open Library key (get_author_info).
• Get Author Photo: Get the URL for an author's photo using their Open Library ID (OLID) (get_author_photo).
• Get Book Cover: Get the URL for a book's cover image using various identifiers (ISBN, OCLC, LCCN, OLID, ID) (get_book_cover).
• Get Book by ID: Retrieve detailed book information using various identifiers (ISBN, LCCN, OCLC, OLID) (get_book_by_id).

Installation# Installing via Smithery

To install MCP Open Library for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @8enSmith/mcp-open-library --client claude
```\n\n### Manual Installation
```bash\n\n# Clone the repository
git clone https://github.com/your-username/mcp-open-library.git
cd mcp-open-library\n\n# Install dependencies
npm install\n\n# Build the project
npm run build
```\n\n## Usage# Running the Server
You can use the MCP Inspector to test the server:
```bash
npm run inspector

Access the MCP Inspector and then test the tool.\n\n### Using with an MCP Client This server implements the Model Context Protocol, which means it can be used by any MCP-compatible AI assistant or client e.g. Claude Desktop. The server exposes the following tools:

• get_book_by_title: Search for book information by title
• get_authors_by_name: Search for author information by name
• get_author_info: Get detailed information for a specific author using their Open Library Author Key
• get_author_photo: Get the URL for an author's photo using their Open Library Author ID (OLID)
• get_book_cover: Get the URL for a book's cover image using a specific identifier (ISBN, OCLC, LCCN, OLID, or ID)
• get_book_by_id: Get detailed book information using a specific identifier (ISBN, LCCN, OCLC, or OLID)

Development# Project Structure
