You can run an MCP server that exposes Open Library data to AI assistants. It lets you search for books by title, find authors, fetch author details and photos, and retrieve book covers and editions through dedicated tools. This enables your AI workflows to discover and present library information quickly and consistently.

How to use

Connect your MCP client to the server using either a remote HTTP endpoint or a local stdio client workflow. Once connected, you can call the available tools to search for books, find authors, fetch author details and photos, and retrieve book covers and editions. Use the tools to assemble structured results that your AI can display or reference in chats, apps, or assistants.

How to install

Prerequisites you need before starting are Node.js v22.x (or newer) and a working environment for running npm commands.

Manual installation steps you can follow to set up the MCP server locally:

Manual installation steps

# Clone the MCP Open Library repository
git clone https://github.com/8enSmith/mcp-open-library.git
cd mcp-open-library

# Install dependencies
npm install

# Build the project
npm run build

Run and test locally with the MCP Inspector

Build the project, then start the inspector to connect your client to the local server. The process uses the MCP Inspector to establish a STDIO transport and run tools like get_book_by_title.

Basic flow you can follow once the build is complete:

npm run inspector

Docker testing

If you prefer running in a container for isolation, you can test with Docker. Build the image and run the container, then connect via the inspector to test tools.

docker build -t mcp-open-library .
docker run -p 8080:8080 mcp-open-library
```
"""
You can then test the server using the inspector, for example:
```
npm run inspector http://localhost:8080
