Zenn MCP server

This Model Context Protocol (MCP) server allows you to integrate with the Zenn publishing platform (https://zenn.dev/) through an unofficial implementation. It offers capabilities to fetch article and book data from Zenn's developer API.

Installation

To get started with the MCP server for Zenn, clone the repository from GitHub:

git clone https://github.com/shibuiwilliam/mcp-server-zenn.git

Usage

Running with the MCP Inspector

You can launch and test the server using the MCP inspector tool. First ensure you have npm installed, then run:

npx @modelcontextprotocol/inspector uv --directory=src/mcp_server_zenn run mcp-server-zenn

After launching, the Inspector will provide a URL that you can open in your browser to begin interacting with and debugging the server.

Adding as an MCP Server

Alternatively, you can add this tool as an MCP server in your configuration:

{
  "zenn": {
    "command": "uv",
    "args": [
      "--directory",
      "/path/to/mcp-server-zenn",
      "run",
      "mcp-server-zenn"
    ]
  }
}

Be sure to replace /path/to/mcp-server-zenn with the actual path where you cloned the repository.

Features

With this MCP server, you can:

• Fetch a list of articles from Zenn
• Fetch a list of books from Zenn

These features leverage Zenn's developer API to provide access to content published on the platform.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "zenn" '{"command":"uv","args":["--directory","/path/to/mcp-server-zenn","run","mcp-server-zenn"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "zenn": {
            "command": "uv",
            "args": [
                "--directory",
                "/path/to/mcp-server-zenn",
                "run",
                "mcp-server-zenn"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

                "--directory",
                "/path/to/mcp-server-zenn",
                "run",
                "mcp-server-zenn"
            ]
        }
    }
}
