MCP LaTeX Server

A comprehensive Model Context Protocol (MCP) server that provides advanced LaTeX file creation, editing, and management capabilities for Large Language Models and AI assistants.

Overview

The MCP LaTeX Server enables AI assistants like Claude to seamlessly work with LaTeX documents through a standardized protocol. It provides tools for creating, editing, reading, and validating LaTeX files, making it easy to generate professional academic papers, reports, presentations, and other LaTeX documents.

Features

  • 📝 Create LaTeX Documents: Generate new LaTeX files from templates or custom specifications

  • ✏️ Edit Existing Files: Modify LaTeX documents with various edit operations

  • 📖 Read File Contents: Access and analyze LaTeX file content

  • 📁 File Management: List and organize LaTeX files in directories

  • ✅ Syntax Validation: Basic LaTeX syntax checking and error detection

  • 🎯 Document Types: Support for article, report, book, letter, beamer, and minimal document classes

  • 📦 Package Management: Automatic handling of LaTeX packages and dependencies

  • 🔧 Template System: Built-in templates for common document types

Prerequisites

Before installing the MCP LaTeX Server, ensure you have:

  • Python 3.8+ installed on your system

  • LaTeX Distribution (recommended for full functionality):

    • Windows: MiKTeX or TeX Live

    • macOS: MacTeX

    • Linux: TeX Live

  • VS Code (for VS Code integration)

  • Claude Desktop or Claude in VS Code (for Claude integration)

Installing LaTeX Distribution

Windows (MiKTeX)

  1. Download MiKTeX from https://miktex.org/download

  2. Run the installer and follow the setup wizard

  3. Choose "Install packages on-the-fly" for automatic package management

Windows (TeX Live)

  1. Download TeX Live from https://www.tug.org/texlive/

  2. Run the installer (this may take some time as it's a large distribution)

macOS

# Using Homebrew brew install --cask mactex # Or download directly from https://www.tug.org/mactex/

Linux (Ubuntu/Debian)

sudo apt-get update sudo apt-get install texlive-full

Linux (Fedora/RHEL)

sudo dnf install texlive-scheme-full

Installation

Method 1: Quick Setup (Recommended)

  1. Clone or download the repository:

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

  1. Run the setup script:

python setup.py

This will automatically install all required dependencies.

Method 2: Manual Installation

  1. Create a virtual environment (recommended):

python -m venv .venv # Windows .venv\Scripts\activate # macOS/Linux source .venv/bin/activate

  1. Install dependencies:

pip install -r requirements.txt

  1. Verify installation:

python latex_server.py --help

Method 3: Using uv (Fast Python Package Manager)

  1. Install uv (if not already installed):

pip install uv

  1. Install dependencies with uv:

uv pip install -r requirements.txt

Configuration

Basic Configuration

The server can be configured to work with specific directories for LaTeX files. By default, it allows access to the current working directory and subdirectories.

Environment Variables

You can set the following environment variables:

# Set the base path for LaTeX files export LATEX_BASE_PATH="/path/to/your/latex/files" # Set logging level export LATEX_LOG_LEVEL="INFO" # DEBUG, INFO, WARNING, ERROR

Configuration File

Create a config.json file in the server directory:

{ "base_path": "/path/to/your/latex/files", "allowed_extensions": [".tex", ".sty", ".cls", ".bib"], "max_file_size": "10MB", "enable_validation": true, "default_document_class": "article", "default_packages": [ "amsmath", "amsfonts", "amssymb", "graphicx", "hyperref" ] }

MCP Integration

Claude Desktop Integration

  1. Locate Claude Desktop Configuration:

    • Windows: %APPDATA%\Claude\claude_desktop_config.json

    • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

    • Linux: ~/.config/Claude/claude_desktop_config.json

  2. Add MCP Server Configuration:

{ "mcpServers": { "latex-server": { "command": "python", "args": [ "C:\\path\\to\\mcp-latex-server\\latex_server.py" ], "env": { "LATEX_BASE_PATH": "C:\\path\\to\\your\\latex\\files" }, "cwd": "C:\\path\\to\\mcp-latex-server" } } }

For uv (recommended for better performance):

{ "mcpServers": { "latex-server": { "command": "uv", "args": [ "--directory", "C:\\path\\to\\mcp-latex-server", "run", "latex_server.py" ], "env": { "LATEX_BASE_PATH": "C:\\path\\to\\your\\latex\\files" }, "cwd": "C:\\path\\to\\mcp-latex-server" } } }

  1. Restart Claude Desktop for changes to take effect.

VS Code Integration with Claude

  1. Install the Claude extension in VS Code

  2. Configure MCP Server in VS Code settings:

Open VS Code settings (Ctrl+, or Cmd+,) and add:

{ "claude.mcpServers": { "latex-server": { "command": "python", "args": ["C:\\path\\to\\mcp-latex-server\\latex_server.py"], "cwd": "C:\\path\\to\\mcp-latex-server", "env": { "LATEX_BASE_PATH": "${workspaceFolder}" } } } }

  1. Alternative: Using tasks.json

Create .vscode/tasks.json in your workspace:

{ "version": "2.0.0", "tasks": [ { "label": "Start LaTeX MCP Server", "type": "shell", "command": "python", "args": ["C:\\path\\to\\mcp-latex-server\\latex_server.py", "--base-path", "${workspaceFolder}"], "group": "build", "presentation": { "echo": true, "reveal": "always", "focus": false, "panel": "new" }, "isBackground": true, "problemMatcher": [] } ] }

Testing the Integration

  1. Start Claude Desktop or Claude in VS Code

  2. Test the connection by asking Claude:

    Can you list the available LaTeX tools?

  3. Create a test document:

    Please create a simple LaTeX article with the title "Test Document" and some sample content.

Troubleshooting

Common Issues

1. Server Won't Start

# Check Python version python --version # Should be 3.8+ # Check dependencies pip list | grep mcp # Run with debug logging python latex_server.py --log-level DEBUG

2. Claude Can't Connect to Server

  • Verify the file paths in your configuration are correct

  • Check that Python is in your system PATH

  • Restart Claude Desktop after configuration changes

  • Check Claude Desktop logs for error messages

3. Permission Errors

# Windows: Run as administrator if needed # macOS/Linux: Check file permissions chmod +x latex_server.py

4. LaTeX Compilation Issues

  • Ensure LaTeX distribution is properly installed

  • Check that required packages are available

  • Use the validation tool to check syntax

Debug Mode

Run the server in debug mode for detailed logging:

python latex_server.py --log-level DEBUG --base-path /your/latex/path

Log Files

Check log files for troubleshooting:

  • Server logs: Available in console output

  • Claude Desktop logs: Check Claude's log directory

  • VS Code logs: Check VS Code's output panel

Advanced Configuration

Custom Templates

Create custom templates in the templates/ directory:

% templates/custom_article.tex \documentclass[12pt]{article} \usepackage{your_custom_packages} \title{{{TITLE}}} \author{{{AUTHOR}}} \date{{{DATE}}} \begin{document} \maketitle {{{CONTENT}}} \end{document}

Security Considerations

  • The server only allows access to specified directories

  • File operations are limited to LaTeX-related extensions

  • Input validation prevents malicious LaTeX code execution

Performance Optimization

  • Use SSD storage for LaTeX files

  • Keep LaTeX distribution up to date

  • Use uv instead of pip for faster dependency management
