LaTeX MathML MCP server

This MCP server converts LaTeX mathematical expressions to MathML format, enabling seamless integration with applications that require mathematical notation rendering. It supports both tool-based conversion and resource-based access following the Model Context Protocol standard.

Installation

To install the LaTeX to MathML MCP server:

1. Clone the repository:

   git clone https://github.com/HappyAny/latex-mathml-mcp-server.git
   cd latex-mathml-mcp-server
   

2. Install the required dependencies:

   npm install mathjax-node
   npm install @modelcontextprotocol/sdk
   

Usage

Starting the Server

Launch the server using Node.js:

node index.js

The server will start and listen for MCP client connections via stdio transport.

Conversion Services

The server provides two ways to convert LaTeX to MathML:

Tool-based Conversion

Use the latex2mathml tool to convert LaTeX expressions:

Request Format:

{
    "latex": "your_LaTeX_expression"
}

Example Request:

{
    "latex": "E = mc^2"
}

Response Format:

{
    "content": [
        {
            "type": "text",
            "text": "<math xmlns=\"http://www.w3.org/1998/Math/MathML\">...</math>"
        }
    ]
}

Resource-based Access

Access mathematical expressions as resources using the URI pattern:

mathml://E%20%3D%20mc%5E2

Note: LaTeX expressions must be URL-encoded in the resource URI.

Client Integration

To connect to this server from an MCP client, add the following configuration to your client's settings:

{
    "mcpServers": {
        "latex-mathml-server": {
            "isActive": true,
            "command": "node",
            "args": [
                "path_to_your_server/index.js"
            ]
        }
    }
}

Make sure to replace path_to_your_server/index.js with the actual path to the server script on your system.

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 "latex-mathml-server" '{"isActive":true,"command":"node","args":["path_to_your_server/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": {
        "latex-mathml-server": {
            "isActive": true,
            "command": "node",
            "args": [
                "path_to_your_server/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.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "latex-mathml-server": {
            "isActive": true,
            "command": "node",
            "args": [
                "path_to_your_server/index.js"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
