Markdown to HTML MCP server

This MCP server converts Markdown to HTML, allowing Claude Desktop to transform markdown content into properly formatted HTML. The server implements the Model Context Protocol specification to provide this functionality.

Installation

Prerequisites

Make sure you have Node.js installed on your system.

Setting Up with Claude Desktop

To use this server with Claude Desktop, you need to add the server configuration to the Claude Desktop config file:

On MacOS:

~/Library/Application Support/Claude/claude_desktop_config.json

On Windows:

%APPDATA%/Claude/claude_desktop_config.json

Add the following configuration to the JSON file:

{
  "mcpServers": {
    "markdown-to-html": {
      "command": "node",
      "args": [
        "/path/to/markdown-to-html/build/index.js"
      ]
    }
  }
}

Make sure to replace /path/to/markdown-to-html with the actual path where you have the server installed.

Usage

Using the Markdown to HTML Conversion

The server provides a tool called markdown_to_html that converts Markdown content to HTML.

To use it, you need to provide the Markdown content as a required parameter called mdContent.

Example Usage in Claude

When using Claude Desktop with this MCP server configured, you can invoke the markdown-to-html conversion functionality by asking Claude to convert your markdown content to HTML.

For example:

1. Ask Claude to convert some markdown to HTML
2. Claude will use the MCP server to process the markdown
3. Claude will return the HTML output

Troubleshooting

If you encounter issues with the server, you can use the MCP Inspector for debugging. This tool helps visualize the communication between Claude and the MCP server.

To access the inspector, you can run it from a terminal if you have the server source code:

npm run inspector

The Inspector will provide a URL that you can open in your browser to access debugging tools.

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 "markdown-to-html" '{"command":"node","args":["/path/to/markdown-to-html/build/index.js"]}'

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": {
        "markdown-to-html": {
            "command": "node",
            "args": [
                "/path/to/markdown-to-html/build/index.js"
            ]
        }
    }
}

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.
