Configuration

Claude Desktop Configuration

Add the server to your Claude Desktop configuration file:

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

{
  "mcpServers": {
    "latexpdf-mcp": {
      "command": "latexpdf-mcp",
      "env": {
        "LATEXPDF_OUTPUT_DIR": "/path/to/your/pdf/directory"
      }
    }
  }
}

Output Directory

By default, PDFs are generated in: C:\Users\Admin\Documents\GeneratedPDF

You can customize the output directory by setting the LATEXPDF_OUTPUT_DIR environment variable in your MCP configuration.

Example configurations:

Windows:

{
  "mcpServers": {
    "latexpdf-mcp": {
      "command": "latexpdf-mcp",
      "env": {
        "LATEXPDF_OUTPUT_DIR": "C:\\Users\\YourName\\Documents\\MyPDFs"
      }
    }
  }
}

macOS/Linux:

{
  "mcpServers": {
    "latexpdf-mcp": {
      "command": "latexpdf-mcp",
      "env": {
        "LATEXPDF_OUTPUT_DIR": "/home/yourname/Documents/PDFs"
      }
    }
  }
}

Usage

Once configured, you can use the server through your MCP-compatible client:

Available Tools

Parameters:

• file_name (string, required): Name of the output PDF file (must end with .pdf)
• latex_source (string, required): LaTeX source code to convert

Example:

\documentclass{article}
\usepackage[utf8]{inputenc}
\title{Sample Document}
\author{Your Name}
\date{\today}

\begin{document}
\maketitle

\section{Introduction}
This is a sample LaTeX document generated via MCP.

\subsection{Features}
\begin{itemize}
    \item Professional formatting
    \item Mathematical expressions: $E = mc^2$
    \item Cross-references and citations
\end{itemize}

\end{document}

PDF Access

After generating a PDF, you can access it via HTTP server:

1. Navigate to the output directory (default: C:\Users\Admin\Documents\GeneratedPDF, or your custom LATEXPDF_OUTPUT_DIR):

cd [YOUR_OUTPUT_DIRECTORY]

2. Start a local HTTP server:

python -m http.server

3. Access your PDFs at http://localhost:8000/[filename].pdf

The server automatically provides download links in this format when PDFs are generated.
