Data4Library

You will run and connect to the data4library MCP Server to access nationwide library data, book search, borrowing status, and reading analytics from the Library Information Naroo API. This MCP Server wraps the API endpoints so your AI tooling can call them in a cohesive, programmable way.

How to use

Use an MCP client to talk to the data4library MCP Server. You can run the server locally or connect to it through an HTTP endpoint if you have one configured. The MCP exposes 25 endpoints for library discovery, book search, availability checks, trends, statistics, and personalized recommendations. You combine tool calls to form complex queries, such as finding nearby libraries, then checking the newest arrivals at those libraries, or querying popular books by region.

How to install

Prerequisites you need before installation are Node.js 18+ and an API key for the Library Information Naroo service.

Option A: Install via NPX (recommended for quick setup)

npx -y @smithery/cli install @isnow890/data4library-mcp

Configure your MCP client or Claude Desktop to load the server using this NPX command. Ensure you set the LIBRARY_API_KEY environment variable to your issued API key.

Option B: Local installation for development or customization

Step 1: Obtain the source and build the project.

git clone https://github.com/isnow890/data4library-mcp.git
cd data4library-mcp
npm install
npm run build

Step 2: Claude Desktop integration (stdio configuration) to run the built server directly with Node.

If you are on Windows, add this to Claude Desktop configuration (adjust paths to your setup):

{
  "mcpServers": {
    "data4library_mcp_stdio": {
      "type": "stdio",
      "command": "node",
      "args": ["/path/to/data4library-mcp/dist/src/index.js"],
      "cwd": "/path/to/data4library-mcp",
      "env": {
        "LIBRARY_API_KEY": "your-api-key"
      }
    }
  }
}

If you are on macOS or Linux, add this to Claude Desktop configuration (adjust paths to your setup):

{
  "mcpServers": {
    "data4library_mcp_stdio": {
      "type": "stdio",
      "command": "node",
      "args": ["/path/to/data4library-mcp/dist/src/index.js"],
      "cwd": "/path/to/data4library-mcp",
      "env": {
        "LIBRARY_API_KEY": "your-api-key"
      }
    }
  }
}

Step 3: Restart Claude Desktop to activate the local server configuration. Ensure your API key is set in the environment and the dist index.js path points to the built file.
