MCP LaTeX Server

A Model Context Protocol (MCP) server for LaTeX file creation, editing, validation, and compilation. Built with FastMCP and Pydantic for type-safe, structured output.

Features

• Create LaTeX documents from parameters or bundled templates (article, beamer, report)
• Edit files with replace, insert, append, and prepend operations
• Read and list .tex files within a secure base directory
• Validate syntax — braces, environments, references, required declarations
• Compile to PDF with pdflatex, xelatex, or lualatex
• Resources — browse and retrieve bundled templates via latex:// URIs

Prerequisites

• Python 3.11.9+
• LaTeX distribution (for compilation):
  • Windows: MiKTeX or TeX Live
  • macOS: MacTeX (brew install --cask mactex)
  • Linux: sudo apt install texlive-full (Debian/Ubuntu) or sudo dnf install texlive-scheme-full (Fedora)

Installation

Using uv (recommended)

git clone https://github.com/RobertoDure/mcp-latex-server
cd mcp-latex-server
uv pip install -e .

Using pip

git clone <repository-url>
cd mcp-latex-server
python -m venv .venv
# Windows
.venv\Scripts\activate
# macOS/Linux
source .venv/bin/activate
pip install -e .

Quick setup (Windows)

python quick_setup.py

This checks Python version, installs dependencies, verifies the server imports correctly, and optionally configures Claude Desktop.

Configuration

The server uses a single environment variable:

Variable	Description	Default
LATEX_SERVER_BASE_PATH	Root directory for all file operations	. (current directory)

All file paths passed to tools are resolved relative to this base directory. Access outside it is denied.
