Getting started & client setup

mcp-latex is a Model Context Protocol server. You register it with an MCP client (an AI assistant), which then calls its tools.

Requirements

• Node.js 20 or newer
• A TeX engine (latexmk/pdflatex) is only needed for the compile tool; check_document and parse_log work without it.

Claude Desktop

claude_desktop_config.json:

{
  "mcpServers": {
    "latex": { "command": "npx", "args": ["-y", "mcp-latex"] }
  }
}

Claude Code

.mcp.json at your project root (or claude mcp add):

{ "mcpServers": { "latex": { "command": "npx", "args": ["-y", "mcp-latex"] } } }

Try it without a client

npx @modelcontextprotocol/inspector npx -y mcp-latex

Call check_document with { "source": "See \\ref{missing}." }.

Run from source

git clone https://github.com/marcelogdomingues/mcp-latex
cd mcp-latex
npm install
npm start
npm test

Example prompts

• "Check my thesis for undefined references and unbalanced environments."
• "Parse this build log and tell me the first real error and its line."
• "Compile main.tex, then fix whatever failed."
