MCP Servers

mcp-latex

An MCP server for LaTeX that enables AI assistants to check documents for errors, parse compiler logs, and compile LaTeX files, helping them fix documents instead of guessing.

README

mcp-latex

A Model Context Protocol (MCP) server for LaTeX. Give an AI assistant (Claude Desktop, Claude Code, Cursor…) the ability to check your LaTeX document, parse compiler logs, and compile — so it can actually fix your thesis or paper instead of guessing. Static analysis works with no TeX install required.

Tools

Tool	Description
`check_document`	Static analysis: undefined refs, duplicate/unused labels, unbalanced environments; lists labels/refs/citations. No TeX needed.
`parse_log`	Turns a `.log` into structured errors, warnings, undefined refs/citations, over/underfull boxes.
`compile`	Compiles a `.tex` with `latexmk`/`pdflatex` if installed; returns parsed errors (graceful if no engine).

Use with Claude Desktop / Claude Code

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

Then ask: "Check my thesis for undefined references and unbalanced environments," or "Compile main.tex and fix the first error."

Why

Writing a thesis in LaTeX means fighting cryptic compiler errors, dangling \refs and \begin/\end mismatches. An AI assistant is great at fixing these — if it can see the actual errors. This server gives it structured eyes on your document. Built from the pain of writing a real master's thesis.
